Thread: Reloading brass hulls for an English Black powder s/b/s 12 gauge.

and MANY modern .12ga arent really .12ga anymore as they are overbored so closer to what was traditionally a .10ga

but correct they still fire same shells just have little if any forcing cone so pattern nicely and have lower pressure.......you can do same thing if making .410 insert for your larger shotgun....use same drill bit right through...its VERY close to 1/2" pipe diameter...but we wont go into how I know this or will be called redneck AGAIN....
