[QUOTE="Mikecr, post: 422603, member: 1521"] A few statisticians hear might get all flip about it... But I agree with 10shts Sbruce suggested if you're capturing cold barrel(1st shot) MVs -with your final load. 1st shots are usually lower in velocity. Way lower. So don't cheat, let the barrel completely cool between shots, as you'd only be cheating yourself. It is important to establish 1st shot standard conditions as far as barrel fouling too. Not to mention everything Sbruce pointed out. I pre-foul totally clean barrels with WS2, and have higher confidence in my 1st shot, than any other. Not that the others are bad,, I just don't really care about them. Oh yeah, another thing. Make sure you level your screens everytime. Believe it or not, any screen angle messes with readings. This stuff is that sensitive.. I put my crosshair on intended target, insert a laser boresighter, and verify the dot is centered the same in each screen. Use the diffusers also(even though screens will work without them). These reduce light variance from day to day. But shooting in the morning one session, to evening in another might cause velocity reading shifts because of sunlight angles. Well that's all I can think of for now. [/QUOTE]
