the first time I went to shoot all there was was a click so I figured the primer didn't go off, without thinking I pulled the slide back and chambered another round and shot it, this is how I got the bulged barrel. I made more than one mistake that I will not make again. As soon as the first one clicked I should have emptied the gun and checked the barrel.
Bad Boy! You were withholding evidence!!
Try a Kart barrel. I forget just whom I was talking with on this, might have been David Sams the gunsmith, but recently someone whose opinion I respect said Kart barrels were as good as you can get.
Charles Petty wrote an extremely interesting article in the Sept/Oct 1998 American Handgunner titled
Accuracy Got You Over a Barrel? He tested thirteen 45ACP barrels in a fixtue and air gaged the things. He had Kart, Wilson Combat, Colt NM, Colt 1991A1, Bar-Sto, Kimber, Chip McCormick, Briely, Ed Brown and some duplicates. The GI barrels, (WW2 High Standard and Colt Nat'l Match), were ranked 5th & 6th out of 13 barrels for accuracy! The best was the Kart and Briley was the worst. The difference between best and worst was around 0.60" at 50 yards. The Kart had an average of 1.36", and the Briley Electro Chemical Machined barrel was 1.99". That is some good grouping at 50 yards.
Petty made the statement that fitting was critical, and based on his test data, I believe more critical than barrel make, assuming a good barrel.
