I'm curious as to what type of bullet I should buy next, at the moment I'm using lead to practice with. But I was looking at full metal profile bullets from Sierra and liked the thought of the full metal profile having higher sectional density than some of the other bullets. I know if I really want to put a hole in something to use a good hard 357 mag or 44 mag but I kind of want to squeeze out what I can out of my 1911 and Glock 30's penetrating power. I figured if I can I'd like to go with the 230 grain bullet but I'm ok with anything 200 grains or over. Any suggestions?
