You can grind the lip on them and the hulls come out like a snap. The one in the center is a 12 to 20...I threw them in the trash.
I use the Silver 10 to 12 and when you stay close to gauge it wrecks the hulls.
My 10 chokes out a tight modified, with Win. AA 7 % 1/2's it throws a beautiful 40 yard pattern.
I just bought a set of Seminole 12 to 20 chamber inserts. I haven't tried them out yet...the gun I bought them for is not Nitro proofed I'm kinda worried about the pressure ?
The only 20 gauge ammo I can afford to shoot much of is the Remington Gun Club.
