I load .45 acp, .44 magnum, 9mm, .357 mag, and .38 spl in handgun, as well as .32 acp, and .380. The only factory ammo I have is expensive self defense ammo, and my handloads for practice duplicate it. I havent shot any .45 acp factory ammo groups in about 15 years. Not sure where I would get 185 grain match JSWC remington bullet loaded factory ammo for a comparison???? Or 200 grain LSWC match ammo either, but both my hand loads are tailored to the guns I shoot them in via experimentation with powder charge weight, bullet type, brand, weight, and OAL. When I used to buy speer lawman .45 ammo 1990?? I really wasn't capable of shooting groups with it..
