I have used the 100 gr btsp Hornady and it works just like ms squared said a better choice is the regular 100 gr Hornady SP interlock. More than a few years back before the manual writers got their tits in a wringer the IMR manual showed 100 gr bullets being loaded with up to 47.0 grs of IMR 7828 at well over 3000fps. latest Hornady manual shows a 45.0 gr max around 2900fps. I need to replace my stock of 100 gr HornSP handloads I will work up to what I reguard as a safe load not what some litigation lawyer tells a manual writer.My 700 has a 22" barrel as well, their isn't much bc difference between the 2 and at under 350 yds it simply isn't an issue. I'll probably get hate mail for this but I think on deer and antelope it is the best 6mm bullet out there in c&c format. Actually works on those animals better than the 95& 100 gr NPT's. good luck MM
