Ran a box of sst's and Amax's out of it and everything seemed to be fine, I have also ran another 100 rounds of wolf steel case. Yesterday I was at the range and first round didn't chamber again only this time I could get extractor to grab the round and it was stuck. Got home and used a cleaning rod to unstick it. Wasn't stuck bad at all.
Tried the trick of seating the round with my finger and see if it falls out on its own. Wolf falls out under gravity but the hornady rounds will not come out even with a hard slam on the butt of the gun. Doesn't take much to get them to drop free with the cleaning rod but I noticed a ring around the top of the bullet Like the chamber was scratching the bullet. I assume this is a short chamber which really sucks since I will more than likely have to pull the barrel and ship it back to AA. Then put it back together when it comes back(after who knows how long) I have read a lot about short chambers lately, maybe the Grendel 2 chamber is the way to go.
My 16" lite is doing the same thing and I have measured everything and confirmed my chamber is short. The "ring" around the bullet is most likely the marks from the rifling because your bullet is touching the lands. I used my hornady measuring tool to confirm ELDs are touching the land at 2.245 in my barrel. Mine also chambers and shoots the shorter bullets like the 110 wolfs and the 90 TNTs better seemingly because those rounds arent pressed up against the lands like the my boxed ELD AMMO is. I have decided to just keep it like this and just load all of my hand loads shorter to see if I can come up with a decent load.
