Berger seating depth test results - what do you think?

[Mikecr]

It may just be me, but my nemesis is 200yds, so that's where I shoot most.
Weird as hell, I can always shoot 100 & 300 tighter than 200.
And when my 200 is right, I'm good everywhere else.

I could not say this is approriate for anyone else. But I can say that preferred development at 300 isn't best for me.

Ok I wanted to share some results of the berger sorting technique video I posted: Let me give you the finer details first.

Rifle; Custom built .284 Win, Defiance Action, Schneider 28" 3 taper fluted 1:9 twist, reamed for neck turned necked up Lapua brass, Jewell Trigger 1.5 lb, Grey Bull bedded stock., Near base and Rings, GreyBull/ Leupold scope, PTG bottom metal.

Load: necked turned Lapua brass. .001 neck tension, Wolf Large primers, 51.4 gr R17, Berger 180 VLD hunting bullets sorted by seating depth. I am getting 2848 fps. In the video I mention that my rifle like them seated .010 in the lands. I subsequently discovered that it actually much prefers then .010 off the lands:

Here is the results: Target is a 50 yard target 1/2" rings. The 6 round group was taken at 302 yards. This makes my rifle approx. 1/4 MOA accuracy



Again the method of sorting the bullets based upon consistent seating depth is as such:

yes but that same load at 100 could be a horrible shooter at even 300 yrds.. thats the reason for shooting longer at first.. I have had a load shoot awesome at 100 yrds... at 300.. 5 inch group.. yes good loads can be produced at 100.. but 200 and 300 will work better .. but like I said just my 2 cents

I have heard this many times, for some reason I just can't get my mind wrapped around why or physically how that can happen. Can you give an explanation??
