Hello all, this weekend I took my .223 to test some loads that had increments of .3 grains from minimum to maximum, and was really anticipating great results. It's a 1x12 twist rate and not knowing any better I previously loaded 62 grain bullets and got 1 inch groups. Everyone said that better groups would come from using a bullets weight more in line with the twist rate. This weekend I used a 50 grain V Max with powder, primer, cartridge prep the same and my groups went heck in a hand basket. Where do you start in finding what your gun likes best? Do you settle on a bullet weight then tinker with powders or vise versa? Thanks as always. C
