Allright....all you experienced roll-your-own specialist....has anyone found distict advantages/disadvantages of utilizing moly-coated projectiles? I am currently loading standard Sierra 165 grain BTHP.308 projectiles, and utilizing 52 grains of IMR4350 to charge each case. My chrony gives me a ten shot average of 2,755 fps, and I am currently shooting benchrest groups of 1/2" MOA at 100 yds. Sierra makes the identical 165 gr BTHP with the moly coating, and I was just curious if utilizing this variant would be even better? I would assume that one would experience less barrel wear, but what about CUP Pressures? What about velocity? Help me out!
