Everything I can get my hands on!
For self defense I look at Lehigh defense or cutting edge bullets.The 27gn green tip ammo will penetrate level lll body armor. It's very difficult to try and duplicate that performance with hand loads at safe pressure. I'm playing with solid copper bullets from Ft.Scott and a couple others but the known powders are not pushing them fast enough with safe pressure to do the job. The TUI ( tumble on impact) design is interesting.
