What you guys think about J&T?

[pinzgauer]

I need advise what to do, buy different ammo and pray it works and never use Hornady or take it to a gunsmith and have it reamed?

The Hornady factory ammo has been fine in my J&T grendel as well as AA. Mine was the original lot's of Hornady which apparently had problems with some tighter (non-std) grendel chambers.

Is it the bullet or the case itself which is too long? When you get the cartridge out, do you see rifling marks in the bullet?

The input to try some wolf is good. If the wolf works and the Hornady does not then it might just be a short chamber and you have early hornady. Later hornady should work.

If the wolf also does not work then something is wrong. Either the wrong or out of spec bolt, extractor, or ejector, or the chamber was not throated or finished properly & J&T should take care of you.
