AR-Stoner 6.5 Grendel barrel short chambered.

[Tedward]

Grendanimal, thanks for your detailed explaination of how to use the modified case. I have a couple, just got them because they were finally available, but haven't used them. Not reloading my own, someone else has volunteered to do it for me. But I did just buy the go/no-go gauges because they became available and wanted to test them due to this trend. Now that your explanation makes a lot of sense, I'm going to check my Satern Barrels also with that method.

I have relied on them being a great barrel manufacture and just put the factory ammo in and have had no issues. I'll check some of my twice fired, for function testing purposes, and check some unfired new barrels too. I wonder if firing a few factory rounds is "clearing" any left behind burs or possible new unlapped imperfections that might be causing the issues you are having.

Again thanks and welcome to the hoard..I don't think you got your welcome yet....
