Can the 6.5 be loaded to make IPSC Major power factor ? For those unfamiliar, this means that BULLET_WEIGHT (in grains) X MUZZLE_VELOCITY (in FPS) must be 320,000 or more. I think the 6.8 is really marginal with a 20" barrel, but would seriously consider the 6.5 if it could make it. Also, any comments on accuracy if it does get there ?

Doesnt the 140 grain bullet get like 2300 fps from a 16" barrel? That would make it.

Hmmm. Yes it would, but I bet the bullet drop would be pretty dramatic. I wonder how light the bullet could and still make major.

All are short, except the 144 FMJBT.


It'd be close, but a 24 inch overwatch might have enough with the 123 scenar.....
