I prefer the 158 grain bullets for the simple reason that they hit to point of aim in all of the guns I have, and several others that I have shot as well. I place a higher value on being able to place the round exactly where the sights are aligned than having more velocity.
Besides the mold I have is a 158 grain LSWC mold. Mine cost me less than one cent each to make.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
