I'm not a fan of thin wall tubes but I guess they have there place. a gunsmith I no up here in Michigan collects lefevers and has installed them in several of his guns. seems crazy to me. I have no problem with opening a over choked barrel a little but I also use spreader wads. my favorite is sold by ballistic products part #072dx12 this is a 12ga wad but they may have 20ga also. this type of wad make a gun that seems un- useable a lot more fun to shoot.

Parker barrels are Holy Relics don't you know, given to Man by the Almighty hmself.
The chokes were never touched by a mortal hand during the manufacturing process.
Often referred to as "Immaculate Constrictions", it would be blasphemy to even consider altering them. :bowdown:

Thanx guys for all the comments - you convinced me not to screw with the barrels. I will enjoy the gun just the way it is. Billy

No,NoNo!No!
I have one or two classics that been debauched by Briley and hate it
