I'd wager many of us have had such mishaps with our toys. Sometimes it costs time and money. I knocked a lever action off the bench after telling myself two minutes earlier to move it before I knock it off. I broke the scope and needed a new one. You learn to shrug it off. Sometimes it's time consuming and costly. Do what you planned to do with the barrel. Exercise patience and accept the outcome. Wether it be time, money , effort or all three,tell yourself it's the price we pay for our passions. Don't get yourself too disgusted or sick over it. It's not worth it. Easier said than done, but just bite the bullet. I once banged up a brand new Steyr Mannlicher AAA grade stock as my semi auto flung the spent cases at it. Numerous dings all over the beautiful stock. I laugh about it now, even though when it happened I was sick to my stomach. lol
