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?
I'd say it's quite low that the rib will come loose bending laterally. It's almost for sure silver brazed anyway. But the ribe might look funny when you're done. You can aways send it back to Simmons for re-setting the rib if it looks bent.
You might look down the barrel from the underside to see if the barrel has a curve left. I've seen a few barrel sets that had curved tubes in them.
