Re: Best 243 bullet for deer?
veeman---I'm using IMR4064. min is 29.4 grains and max is 34.2 grains, which will get you about 2800 fps. IMR 4831 at min of 35.0 grains will get you about 2500 fps and max of 42.5 will get you way up to about 3000 fps. The same goes for H4831 with min of 36.7 grains to max of 45.5 grains. The B.C. is 0.405 and C.O.L. is 2.630 for the 100 grain BTSP. The straight SP has a B. C. of 0.381 and the same C.O.L. and can be loaded under those same spec for those different powders. The S.D. on both is o.242.
You may even want to try their 105 grain A-MAX. Hornady touts it as a great long range bullet for the .243. It has a S.D. of 0.254, a B.C. of 0.500 and same C.O.L. as the others. A couple of max loads are 39.5grains of IMR 4831 to get about 2700 fps, H4350 with max of 41.0 grains to get about 2800 fps. My book also shows a max of 47.7 grains of WIN WMR will take it up to 3000 fps. Hope that helps a little!
