Bayou 180 oal 1.190 6 in Cameron Unless your SD is huge and you are unlucky, sure. I've run 165.5 at numerous matches and never went minor. Had to shoot a few extra rounds here and there, but then I like a challenge. Link to comment Share on other sites More sharing options...
Corey Posted February 12, 2012 Share Posted February 12, 2012 170 is my goal for Major. Id take 169 if the SD was pretty good. Link to comment Share on other sites More sharing options...

MarkCO Posted February 12, 2012 Share Posted February 12, 2012 Low was 924 fps hi 949 fps. Based on the numbers, you should be fine. Link to comment Share on other sites More sharing options...
al503 Posted February 12, 2012 Share Posted February 12, 2012 Based on the numbers, you should be fine. Yup. I'm perfectly comfortable with 169 if none of the rounds through the chrono dip below 165. Link to comment Share on other sites More sharing options...
gng4life Posted February 12, 2012 Share Posted February 12, 2012 Yeah, I hit 165.1 at Area 6 one year, that was scary. If you are chrono'ing now as cold as it's been the last few days, you may want to check them again a few weeks before those matches. I think you will be okay with Solo but you never know. Now I shoot for 170-172 at home in hotter weather. I chrono'ed last year at three major matches between 169-171. Also, I know you did a 10 round average but I don't do that anymore. Yeah, I've read on here about 10, 15, 20, and 30 rounds averages but do they do that at a Major? No, they take 3 rounds and average them. So I do about 10 - 20 groups of three round shots and look at those averages. If anyone goes below about 167, something gets changed to move up the PF. Good luck...

Bayou 180 oal 1.190 6 in Cameron Not enough information. How many rounds tested? What's your SD? What's the average of the slowest 6 rounds? Are all rounds 165 or higher? Have you replicated testing in different weather conditions? Have you checked bullets for consistency? Link to comment Share on other sites More sharing options...

Larger samples give you a better predictor for what any given round will do. If you want to replicate what happens at a match, test samples of 20 rounds and measure the average of the slowest 6 rounds. If they pass, your overall average is where you'd like it to be, and your SD is manageable, you're good to go. BB Link to comment Share on other sites More sharing options...

BB +1 At the end of a chrono session I average my absolute slowest rounds as a sort of worst case scenario. Link to comment Share on other sites More sharing options...

I replicate what happens at a match and I do not plan on deviating from it any time soon. It is just logical, they test three random rounds, I test three random rounds, etc. After the session, I do take a look at the slowest rounds and get the worst possible scenario but I feel the three round average groups are closer to what happens in the real world...to each his own.
