So been shooting the 105 berger hybrids in a 20" Howa CF 6 arc - 1/7.5 twist. About 125 rounds down it and the load seems to sped up a bit and has settled about 2775 FPS average - at least thats what the last 25 rounds shot got me to. At the 6-7k elevation I normally hunt, that gets me 2k FPS to around 600 yards and 1800 fps to around 750. (Which is farther than I normally shoot at game)

But with these new 116/120 class bullets, the experimenter in me wants to play around with them a bit. If I can safely acheive around 2625 FPS for either of these bullets, the ballistic calculators add around 100 yards of range even with them starting 150fps slower.

Think it worth it play with the bigger bullets or should I leave good enough alone? Right or Wrong, there has always been a part of me that believes that accurate speed kills - something comforting about having that extra 150 fps with the 105?

Maybe a compromise and try the 109's and see if they can move along at say 2725-30ish????
