Hundreds, thousands, ten thousands. OK. .01 to .02. (It has been a while since I took math). I would also like to use the gun as a home defense gun, but I would hate to use it and have it blow up on me. I wouldn't feel too bad about using it at the skeet range because Cowboy Shooting is very big in this area, (although I don't do it) and one of the events is shooting with a shortened barrel at skeet. One of the guys at our club brings out his "coach gun" all the time. So, I would just to try it out to see if the guy who rebuilt it did as good of a job as he said he did. If I could get longer barrels for it I would. But I am going to put a leather covered pad on it and leave it as is. Or maybe sell it as a cowboy shooter. So, thanks for the input. I'll try it out this weekend. Good luck.
