A friend recently bought a new Ruger 1911 and had been shooting it with no issues with jacketed bullets. He wanted to try some of my Hi-Tek coated boolits as the jacketed was breaking his wallet. He called sometime later and said he was getting leading so I advised him to check the crimp, etc. He did this and made a couple of adustments but still was getting leading.
He brought the barrel over to my house so I could slug it. It was at .4515" or so which is fine. He had a couple of his reloads with my boolits in them so in looking at them I noticed the ogive had a cut line around one of the boolits. The oal was too long causing the boolit to hit the rifling before the action was completely closed. My boolits are sized to .452".
The oal was not the leading problem but the end of the barrel at the front of the chamber is. I took a loose coated boolit and tapped it in the end of the rifling from the chamber and the coating and some lead was cut off the boolit. The end of the chamber is very abrupt and very sharp. He is going to take it to a gunsmith to see if he can get it beveled some to eleminate this problem. Oh, and I took a jacketed bullet and tapped in in the chamber end of the rifling and it also cut some copper from the bullet!
