For big game and other things requiring heavier bullets 8-9 twist is what you need. For varmint a 10 works well.
What absolute horse shyt ! There are tons of good deer weight bullets that'll shoot just fine out of the standard factory 10 twist .243. My 10 twist Tikka shoots sub MOA with 100 gr. Hornady interlock, 95 gr SST's, 100 gr Sierra pro hunter, 100 gr core lokt's, 100 gr Federal power shoks {factory} and 85 gr Sierra BTHP Gamekings. Geezus most of us don't give a rats azz about shooting high BC target bullets at flies in outer space and are fine with doing a little bit of hunting before we pull the trigger.
