installing 10mm barrel

[greatgoogamooga]

Got a 10mm non-ramped barrel and a slide for my Essex frame. HAd to use a shorter link to get it to lock up (earlier thread) and now it cycles beutifully with a tight lock up....when unloaded. When loaded the rounds jam, nose up, in the throat/opening/breech, before then can enter the chamber.

My first suspect is the gap between the frame ramp and the barrel, which measures up at around .060ish. About twice the reccomended distance. The mag is a Mec-Gar 10mm magazine and the ammo is Remington 10mm flatpoints. The slide is fitted with a 24# recoil spring. The slide is an Essex 40S&W slide. The barrel is a used Colt.

Any thoughts?

I can tell you that a Colt 10mm barrel I own looks like it was finished with a hand grinder. Out of round and rough as a cob. It does function, but I don't think it's worth wasting any time on. I vote Barsto.

I'm wondering the same. The throat looks like it was polished with a checkering file. I didn't think Bar Sto made an unramped 10mm (my Brownells catalogue doesn't show one).

I think if you go to their web site they have one listed. I hope so because my wife ordered one for my Christmas gift. I specified unramped. It's a little late arriving. She's is supposed to call them today. I'll let you know if I find something out. Kart may chamber a barrel in 10mm, but they don't have a web site and I don't have their number.

No news from Barsto.

BarSto did and still does make non-ramped 10mm 1911 barrels, I have one sitting on my bench as I type this. You are describing a three point jam, bullet nose, rim, and somewhere along the case. I am concerned that you have 0.060" distance from the edge of the frame feed ramp to the edge of the barrel feed ramp. I am thinking either the frame feed ramp is too steep, the slide stop pin is too far forward in the the receiver, the link is way too short, or the barrel has been over throated and possibly dangerous.

The more I look at this barrel, the more I think it was overthroated. A .45 barrel drops in pretty as you please with a good gap at the feed ramp. I'm gonna look for a new barrel and turn this one into a Christmas tree ornament. Should look nice next to the lighted AA shotgun shells :) (my wife isn't reading this, is she?)
