the only guys keep your flying solo

2
00:00:06.360 --> 00:00:08.190
today and gun a brunch because caleb

3
00:00:08.190 --> 00:00:09.690
is currently lost on the other side

4
00:00:09.690 --> 00:00:12.210
of the stargate where he is allegedly

5
00:00:12.360 --> 00:00:17.039
small confused frightened cold afraid but is

6
00:00:17.039 --> 00:00:19.320
learning to love the fn five seven

7
00:00:19.320 --> 00:00:19.740
round

8
00:00:20.160 --> 00:00:21.390
as well as the p ninety that

9
00:00:21.390 --> 00:00:24.090
fires it and a greater appreciation for

10
00:00:24.090 --> 00:00:25.830
bull pups will be had by all

11
00:00:26.220 --> 00:00:27.690
this episode is still brought to you

12
00:00:27.690 --> 00:00:29.730
by guns dot com and tourists usa

13
00:00:30.090 --> 00:00:32.760
maker of fine firearms and a location

14
00:00:32.790 --> 00:00:35.280
where you can go get them so

15
00:00:35.520 --> 00:00:38.280
check out this website like share subscribe

16
00:00:38.490 --> 00:00:40.290
force people to watch this by

17
00:00:40.320 --> 00:00:44.220
a bribing the necessary bribery always works

18
00:00:44.640 --> 00:00:46.830
and today i want to discuss the

19
00:00:46.830 --> 00:00:49.320
topic of zeros one last time so

20
00:00:49.320 --> 00:00:51.120
we've covered twenty five meters euros twenty

21
00:00:51.120 --> 00:00:52.710
five years zeros and why those are

22
00:00:52.710 --> 00:00:55.290
bad for rifles but great for handguns

23
00:00:55.290 --> 00:00:57.630
and pcc his leg got that guy

24
00:00:57.630 --> 00:00:59.940
behind me there i want to talk

25
00:00:59.940 --> 00:01:00.480
about enough

26
00:01:00.480 --> 00:01:02.880
other topic i've seen float around online

27
00:01:02.880 --> 00:01:04.260
a little bit though and that is

28
00:01:04.260 --> 00:01:07.560
the concept of the perfect zero what

29
00:01:07.560 --> 00:01:09.420
is the perfect zero for a given

30
00:01:09.480 --> 00:01:13.500
rifle and ammunition cock combination so if

31
00:01:13.500 --> 00:01:15.960
you have seventy seven green five point

32
00:01:15.960 --> 00:01:17.550
five six or seventy seven grain to

33
00:01:17.550 --> 00:01:19.620
twenty three remington out of a fourteen

34
00:01:19.620 --> 00:01:20.640
and a half inch barrel and your

35
00:01:20.970 --> 00:01:22.830
running a one nine three arctic is

36
00:01:22.830 --> 00:01:24.900
there an optimal distance you can zero

37
00:01:24.900 --> 00:01:27.540
at that gives you the greatest effect

38
00:01:27.570 --> 00:01:29.880
and the answer to that is yes

39
00:01:29.940 --> 00:01:32.250
technically there is in precision shooting they

40
00:01:32.250 --> 00:01:34.590
call it the maximum point blank range

41
00:01:34.710 --> 00:01:38.520
and m p b r dyslexia kicking

42
00:01:38.520 --> 00:01:40.620
my ass there so your maximum point

43
00:01:40.620 --> 00:01:40.800
blank

44
00:01:40.860 --> 00:01:44.670
branch m pbr there is a specific

45
00:01:44.670 --> 00:01:46.109
range that as long as you are

46
00:01:46.109 --> 00:01:47.736
shooting at a target of certain size

47
00:01:47.736 --> 00:01:48.960
so like twelve inches if you have

48
00:01:48.960 --> 00:01:50.400
a twelve inch target as long as

49
00:01:50.400 --> 00:01:51.690
you have that target of a certain

50
00:01:51.690 --> 00:01:54.390
size and you are within your mtb

51
00:01:54.390 --> 00:01:56.640
are you have a zero that you

52
00:01:56.640 --> 00:01:58.530
can put into your scope that will

53
00:01:58.530 --> 00:02:00.840
guarantee you a hit either low or

54
00:02:00.840 --> 00:02:00.960
high

55
00:02:00.960 --> 00:02:02.790
high on a target as long as

56
00:02:02.790 --> 00:02:04.830
you hold center of that target you

57
00:02:04.830 --> 00:02:07.950
will hit the the example i have

58
00:02:07.950 --> 00:02:09.704
is my m sixteen a for my

59
00:02:09.720 --> 00:02:11.490
m sixteen a four and currently running

60
00:02:11.520 --> 00:02:14.430
a leopold mark five three point six

61
00:02:14.430 --> 00:02:16.830
eighteen scout the tremor radical in him

62
00:02:17.580 --> 00:02:19.830
and you if you have a kestrel

63
00:02:19.830 --> 00:02:21.120
fifty seven hundred with a pliable

64
00:02:21.120 --> 00:02:22.860
mystics you can find this really easily

65
00:02:22.860 --> 00:02:24.150
the software will do the math for

66
00:02:24.150 --> 00:02:26.070
you but if you don't have that

67
00:02:26.070 --> 00:02:27.660
you can do this math by hand

68
00:02:27.660 --> 00:02:29.280
and you can use other ballistic software

69
00:02:29.280 --> 00:02:30.930
to help get to that range

70
00:02:32.610 --> 00:02:34.380
but the applied ballistics software gives you

71
00:02:34.380 --> 00:02:36.000
your npr art does all that math

72
00:02:36.000 --> 00:02:37.650
for you real quick which is really

73
00:02:37.650 --> 00:02:39.420
nice so i have a maximum point

74
00:02:39.420 --> 00:02:40.920
blank range on that m sixteen of

75
00:02:40.920 --> 00:02:43.080
three hundred and sixty six yards and

76
00:02:43.080 --> 00:02:44.160
to get that i have to take

77
00:02:44.160 --> 00:02:45.660
my one hundred yards zero which is

78
00:02:45.660 --> 00:02:46.920
the native one that i use on

79
00:02:46.923 --> 00:02:48.420
the gun because it's got a precision

80
00:02:48.420 --> 00:02:50.430
rifle scope on it most of those

81
00:02:50.430 --> 00:02:52.260
written for one hundred and then

82
00:02:52.350 --> 00:02:52.920
i

83
00:02:54.180 --> 00:02:55.890
i slipped that scale one point one

84
00:02:55.890 --> 00:02:58.710
mills up so i've i've adjusted to

85
00:02:58.710 --> 00:03:00.480
one point one on the top tour

86
00:03:00.480 --> 00:03:02.610
it and then on any twelve inch

87
00:03:02.610 --> 00:03:05.311
target with my seventy seven grain a

88
00:03:05.340 --> 00:03:07.890
cease your match king i will anything

89
00:03:07.920 --> 00:03:09.540
from zero to three hundred and sixty

90
00:03:09.540 --> 00:03:11.880
six yards i will hit as long

91
00:03:11.880 --> 00:03:13.260
as it is a twelve inch target

92
00:03:13.980 --> 00:03:14.160
and

93
00:03:14.160 --> 00:03:17.160
then he gives me and it gives

94
00:03:17.160 --> 00:03:18.540
me my my holdovers and a little

95
00:03:18.540 --> 00:03:20.700
bit more data in the casserole that

96
00:03:20.700 --> 00:03:22.170
allows me to know all right well

97
00:03:22.800 --> 00:03:24.210
how it also gives me range and

98
00:03:24.215 --> 00:03:26.220
data so if i look at my

99
00:03:26.280 --> 00:03:27.750
my scale if i look at my

100
00:03:27.780 --> 00:03:30.060
mill scale if i see a target

101
00:03:30.060 --> 00:03:32.940
that is point nine one i believe

102
00:03:32.940 --> 00:03:33.990
it was if it was point nine

103
00:03:33.990 --> 00:03:34.320
one

104
00:03:34.410 --> 00:03:37.410
mills were smaller than my my risk

105
00:03:37.410 --> 00:03:39.480
of of missing at that distance if

106
00:03:39.480 --> 00:03:40.440
i knew it was a twelve inch

107
00:03:40.440 --> 00:03:42.660
target and am below point nine one

108
00:03:42.690 --> 00:03:44.760
and the mill scale that it's too

109
00:03:44.760 --> 00:03:46.410
far away i'm going to miss i

110
00:03:46.410 --> 00:03:48.390
have to i have to start now

111
00:03:48.570 --> 00:03:51.720
hauling over i'm outside max point blank

112
00:03:52.350 --> 00:03:54.300
so that range does exist a quote

113
00:03:54.300 --> 00:03:54.480
unquote

114
00:03:54.480 --> 00:03:57.600
a perfect zero does exist and you

115
00:03:57.600 --> 00:03:58.800
can work that out you can work

116
00:03:58.800 --> 00:04:00.870
out the math on that formula so

117
00:04:00.870 --> 00:04:02.580
that you can take your site so

118
00:04:02.580 --> 00:04:04.470
if you have a precision rival site

119
00:04:04.530 --> 00:04:06.480
or a semi precision rifle sight like

120
00:04:06.480 --> 00:04:07.770
an l p b o like that

121
00:04:07.800 --> 00:04:09.930
eotech vudu ten x over there that's

122
00:04:09.930 --> 00:04:12.990
got a adjustable top topped her that

123
00:04:12.990 --> 00:04:14.280
you can use it's not cac

124
00:04:14.820 --> 00:04:16.230
you can throw that adjustment in and

125
00:04:16.230 --> 00:04:18.330
then you have a point of aim

126
00:04:18.450 --> 00:04:21.420
relative point of impact in the rifle

127
00:04:21.780 --> 00:04:24.870
so very cool you'll see you'll see

128
00:04:24.870 --> 00:04:27.000
it floating around people people doing the

129
00:04:27.000 --> 00:04:28.560
equation and saying like oh well the

130
00:04:28.830 --> 00:04:31.170
the divorce perfect zero distance is seventy

131
00:04:31.170 --> 00:04:32.950
six yards are the og's perfect this

132
00:04:32.950 --> 00:04:34.680
is your distance eighty three yards or

133
00:04:34.680 --> 00:04:34.800
so

134
00:04:34.800 --> 00:04:37.980
nothing like that that remember guys is

135
00:04:37.980 --> 00:04:41.550
for a specific ammunition and optical height

136
00:04:41.550 --> 00:04:44.220
combination you need your ammo because you

137
00:04:44.220 --> 00:04:46.140
need your ballistic data for the ama

138
00:04:46.140 --> 00:04:47.880
you need it's drag coefficient it's ballistic

139
00:04:47.880 --> 00:04:50.280
coefficient and you need its muzzle velocity

140
00:04:50.700 --> 00:04:52.410
if you don't have that data then

141
00:04:52.410 --> 00:04:53.580
whatever you read on the internet or

142
00:04:53.580 --> 00:04:54.960
whatever you saw does

143
00:04:54.960 --> 00:04:56.580
isn't match up to your rifle it

144
00:04:56.580 --> 00:04:59.280
can be close because most fifty five

145
00:04:59.280 --> 00:05:01.800
green loans are within arrange most sixty

146
00:05:01.800 --> 00:05:03.270
two reign five five six loads are

147
00:05:03.270 --> 00:05:05.250
within range same thing with three o

148
00:05:05.250 --> 00:05:07.560
eight loads because sammy specs of ng

149
00:05:07.567 --> 00:05:08.970
so your three weight loads can be

150
00:05:08.970 --> 00:05:11.220
within the defined range so you can

151
00:05:11.220 --> 00:05:13.830
get close which is why bd c's

152
00:05:14.340 --> 00:05:15.120
generalized media

153
00:05:15.150 --> 00:05:17.370
see radicals exist and you're able to

154
00:05:17.430 --> 00:05:19.590
you're you're able to make these generalized

155
00:05:20.280 --> 00:05:23.580
presumptions with your zeros but you can

156
00:05:23.580 --> 00:05:25.740
math out that perfect zero for an

157
00:05:25.740 --> 00:05:27.420
impact size you just have to also

158
00:05:27.420 --> 00:05:29.550
keep in mind how you want to

159
00:05:29.550 --> 00:05:31.410
address and engage the targets is a

160
00:05:31.410 --> 00:05:33.420
center hold with a high hit acceptable

161
00:05:33.840 --> 00:05:35.280
if it is then matched

162
00:05:35.280 --> 00:05:36.930
on the blank range working that out

163
00:05:37.230 --> 00:05:38.280
is going to work well for you

164
00:05:38.580 --> 00:05:40.320
if it is not acceptable if you

165
00:05:40.320 --> 00:05:42.150
cannot have a lot of over the

166
00:05:42.150 --> 00:05:45.240
radical type shots which might be more

167
00:05:45.660 --> 00:05:47.160
more in tune with either a red

168
00:05:47.160 --> 00:05:48.930
dot equipped opic or an lp b

169
00:05:48.930 --> 00:05:51.330
o equipped optic where you want the

170
00:05:51.330 --> 00:05:53.040
optic to pretty much be the top

171
00:05:53.040 --> 00:05:55.230
of the ballistic arc you don't want

172
00:05:55.230 --> 00:05:55.440
a lie

173
00:05:55.442 --> 00:05:57.210
lot of play above it then you're

174
00:05:57.210 --> 00:05:58.560
not to want to use and and

175
00:05:58.560 --> 00:06:01.080
pbr a type zero or mtb r

176
00:06:01.080 --> 00:06:02.760
type setup because then you're going to

177
00:06:02.760 --> 00:06:05.430
have variance on both above and below

178
00:06:05.430 --> 00:06:07.620
your point of impact to a pretty

179
00:06:07.620 --> 00:06:10.410
significant degree or you can set that

180
00:06:10.440 --> 00:06:12.270
impact zone you can if you've got

181
00:06:12.270 --> 00:06:13.830
this offer you can set that impact

182
00:06:13.830 --> 00:06:15.330
zone to be rather tight

183
00:06:15.600 --> 00:06:17.190
you can set it so that your

184
00:06:17.220 --> 00:06:19.830
your npr size impact area is only

185
00:06:19.830 --> 00:06:22.380
four inches or six inches and it

186
00:06:22.380 --> 00:06:24.060
will adjust the math accordingly and it

187
00:06:24.060 --> 00:06:27.060
will give you both be adjustment from

188
00:06:27.060 --> 00:06:28.440
your zero so you don't have to

189
00:06:28.500 --> 00:06:30.780
zero at a specific distance you can

190
00:06:30.780 --> 00:06:34.020
zero at a a normalized distance like

191
00:06:34.020 --> 00:06:35.760
fifty or one hundred

192
00:06:36.030 --> 00:06:37.500
and then you can just adjust from

193
00:06:37.500 --> 00:06:39.090
there to the mtb rs era which

194
00:06:39.090 --> 00:06:41.370
will be up and down depending on

195
00:06:41.370 --> 00:06:43.080
whether you used fifty or one hundred

196
00:06:43.080 --> 00:06:45.150
as your baseline so don't go chasing

197
00:06:45.150 --> 00:06:48.000
this the crazy zero instead use a

198
00:06:48.030 --> 00:06:50.580
defined zero because those distances are usually

199
00:06:50.580 --> 00:06:53.280
easier to find on ranges so you

200
00:06:53.280 --> 00:06:55.440
find fifty yard bays you find one

201
00:06:55.440 --> 00:06:55.920
hundred jar

202
00:06:55.980 --> 00:06:57.840
bass it's very rare that you're able

203
00:06:57.840 --> 00:06:59.880
to find a perfect like seventy six

204
00:06:59.880 --> 00:07:03.180
or eighty seven or whatnot yard and

205
00:07:03.270 --> 00:07:05.966
and make that and then properly make

206
00:07:05.966 --> 00:07:08.010
sure that's calibrated from your firing point

207
00:07:08.010 --> 00:07:09.240
your bench and everything like that if

208
00:07:09.240 --> 00:07:11.820
you can cool i guess but if

209
00:07:11.820 --> 00:07:14.550
you can't start with a conventional zero

210
00:07:15.360 --> 00:07:16.080
at your fifty

211
00:07:16.080 --> 00:07:18.270
or one hundred and then slip the

212
00:07:18.270 --> 00:07:20.790
adjustment but make sure all the settings

213
00:07:20.790 --> 00:07:22.800
are properly accounted for so if you

214
00:07:22.800 --> 00:07:24.690
can only have two inches of variance

215
00:07:24.720 --> 00:07:26.040
up or down you have to set

216
00:07:26.040 --> 00:07:28.260
your mp pr target size to a

217
00:07:28.260 --> 00:07:29.640
four inch target so you have two

218
00:07:29.640 --> 00:07:31.380
inches of variance up and two inches

219
00:07:31.380 --> 00:07:33.120
of variance down and it will give

220
00:07:33.120 --> 00:07:36.240
you that adjustment or as ira

221
00:07:36.240 --> 00:07:38.820
i commend most people do live with

222
00:07:38.820 --> 00:07:41.880
your conventional zeros and learn your offsets

223
00:07:41.940 --> 00:07:44.760
your offsets for fifty aren't aren't too

224
00:07:44.790 --> 00:07:47.220
dramatic they're a couple inches up and

225
00:07:47.220 --> 00:07:49.260
then accomplishes down holding over at greater

226
00:07:49.260 --> 00:07:51.690
distance for one hundred for most rifles

227
00:07:51.690 --> 00:07:53.760
that's a very very flat trajectory so

228
00:07:53.760 --> 00:07:56.220
there is no offset above

229
00:07:56.550 --> 00:07:59.580
it all just starts dropping as you

230
00:07:59.580 --> 00:08:00.780
get beyond a hotter one hundred and

231
00:08:00.780 --> 00:08:02.670
fifty yards depending on around your shooting

232
00:08:03.180 --> 00:08:06.390
so learn your offsets learn the holdovers

233
00:08:06.540 --> 00:08:08.340
use those marks that are inside the

234
00:08:08.340 --> 00:08:10.526
site or use yours or learn those

235
00:08:10.526 --> 00:08:11.970
site pictures when it comes to dot

236
00:08:11.970 --> 00:08:15.150
optics cause seeing seeing range and then

237
00:08:15.150 --> 00:08:16.560
using the dot optic to

238
00:08:16.590 --> 00:08:19.260
pick a hold for center center high

239
00:08:19.320 --> 00:08:21.600
you know dot between the shoulders wort

240
00:08:21.660 --> 00:08:24.330
hold above the head is not too

241
00:08:24.330 --> 00:08:26.040
difficult and it's easier

242
00:08:27.420 --> 00:08:29.880
it's easier in the learning process it's

243
00:08:29.940 --> 00:08:32.490
easier to build those patterns as visual

244
00:08:32.490 --> 00:08:34.590
patterns if you do that for your

245
00:08:34.590 --> 00:08:37.500
zero process than trying to over mathew

246
00:08:37.500 --> 00:08:40.950
or zeros so don't chase the perfect

247
00:08:40.950 --> 00:08:45.390
zero chase the recognisable shot patterns is

248
00:08:45.390 --> 00:08:47.280
my recommendation that's all

249
00:08:47.280 --> 00:08:49.110
all i got for today guys i'll

250
00:08:49.110 --> 00:08:50.820
see if caleb's back next week if

251
00:08:50.820 --> 00:08:52.588
he's not i'll come up with something

252
00:08:52.588 --> 00:08:53.940
else to chat about later
