Hey guys I'm in a pinch.
I had some 9mm 147 grain lead cast that I loaded up and had issues with my two Storm Lake 9mm barrels that I corrected most issues with a special Lee Factory Crimp (bulge buster) die. The Glock 17 barrel was manufactured in 2008 or there abouts. It is stainless and very well machined. It fit right in my G17 Gen II without fitting.
I recently purchased a new Storm Lake Glock 34 barrel and had it isonite coated. The barrel hood needed to be fitted slightly.
I thought I had the issue licked but I tried loading some lead cast 124 grain bullets and issues arose again. The Glock 17 stainless barrel chambers them fine but the new Glock 34 isonite barrel is tight enough to stop the round from chambering.
Here are pics with the fresh reloads, then the rounds reversed. The Glock 34 barrel is on the left and the Glock 17 barrel on the right.
I though perhaps I seated the bullet too deep and due to the taper of the case was causing it to hang up toward the front of the case. I backed my bullet seater out and adjusted it to slowly checking both barrels but the seating depth is more of an issue if it's too far out and engages the lands of the rifling.
So what's going on with this new Glock 34 isonite coated barrel? My first thought was the chamber is excessively tight (not in SAAMI specifications) or it’s just cut to minimal specifications and perhaps the isonite added a few thousands to the barrel. Does this occur? The new markings on the barrel and perhaps new machinery allow a tighter cut to even a tighter end of specification.
I'm looking for a set of 9mm chamber gages go/no go to check this Glock 34 9mm chamber. So if anyone has a set let me know so I can check it. Thank you.
