my experiment will be with Missouri bullet co 158 grain no lube groove match hi tek coated bullets vs Acme 148 gr button nose wad cutters no lube groove Hi tex coated as well. both these will be in front of #3.5 grains of bullseye
I had a 3" M60 that shot 148 gr wadcutters well, even when driven to velocities a bit stouter than typical "midrange" target loads... FWIW, here is some 148 grain lead, .38 Special data I have used with the following results. Worked well for me, please use and consider at your own discretion... Probably my favorite round to reload.
