I DO NOT like slugs .001 over unless they are 38 hbwcs 750 fps & under. I like flat base wad cutters-- swcs-- all pistol calibers-- but u have to make them yourself if u wont to go faster--Its like hot rodding--If you push it faster one thing aint gona work. Stick with your original thinking. I shoot any speed I like up the max with wheel weights & 15% lino. Casting aint that hard & no lead problems. SKIP has the prettiest boolits.
