I have a Win Mod 12 in 20ga, 2-barrel set numbered to the gun, with Simmons vent ribs on both barrels. The 30" Full barrel shoots to POA, but the 26" IC barrel shoots way left. Don't want to bore an eccentric choke in the IC barrel because I want as much choke as I can get. Have not fixed that barrel because I'm reluctant to try bending it. Anybody know what the likelihood is that the rib solder will pop loose during a minor bending operation?
