Just got a henry Big Boy Steel carbine in 357. I added a Williams peep and am loading Lee 358 158 rf with a healthy dose of old Hercules 2400, no gas check. This gun is an awesome weapon! super smooth action and at 75 yards I shot a 7 shot group of three inches dead center. Boolits are not sized, just 50-50 wwpb water dropped from the mold and loaded. I would highly suggest this setup to anyone considering a 357 carbine. Mine is the 16" barrel version with the large lever loop. Perfect Vermont mountains and swamps whitetail woods gun. Anyone else have one?
