Since I am new to collecting and shooting SxS shotguns i have to ask. Now dont laugh but What will it do if you shoot with a bore that has light pitting,or moderate or heavy? Does this cause more pressure or just make the gun less accurate? and since I can borrow a micrometer what is the min barrel thickness for a 10gauge LeFever? I am amazed at the amount of knowlege on this forum. I have read to page 90 and learn something new on every page.
