rocketman: good post... same thing can be accomplished with briley insert tubes. I like 26" 20 ga tubes in 30" 12 gauge guns. adding weight to the barrels changes the balance of the gun and seems to improve swing for me. in a 12 gauge gun, I shoot 7/8 loads most of the time. same as the standard 20 gauge load. guns so equipped pattern wonderfully. ever heard of the routledge bored .22? same idea cept in a 12 gauge shotgun.

keep it simple and keep it safe...
