6.5 Creedmoor reload issues

[The Lawn Ranger]

So I started reloading 6.5 Creedmoor for my new JP LRP-07 and I am having some occasional
issues with my reloads not chambering and leaving a stuck bolt and cartridge which is annoying at best. I cleaned the chamber
really well and FL sized with a Hornady match die so that all cases seat all the way into a L.E. Wilson Trimmer
Case Holder. Frankly, I have never experienced anything like this with any semi I have owned.

I must say that the gun does beat the shit out of the brass, leaving a visible dent/ding about 1/8"-1/4" below the neck.
I have adjusted the gas to minimize this issue. I would like to avoid purchasing any small base dies at this point.

Any recos?

Since you mention the hornady die:

I don't think a case gage is adequate for evaluating what a size die is doing to your brass.

Have you sharpied the cartridge to see where its sticking?

I will try that.....I have a feeling the cases might be damaged beyond usability.

Sounds like you're letting the BCG slam them into the chamber. Which is OK, unless you're trying to solve a problem like this one.

Remove your firing pin so you DON'T get an unintended "bang", and find a sticker by cycling some cartridges EASILY through the rifle.Cartridges should chamber and go into battery without fuss.

My suspicion is ALL of your ammo is a little big and none will chamber easily.

Anyway, find a sticker, sharpie it up and find out where its rubbing. Then report back.

EDIT: or just remove the upper and drop cartridges in the chamber. If they don't drop in, bounce and make a "pink" sound, that's trouble, and indicates the case is too fat. Don't force it in much. Pop it back out with a gentle tap from a cleaning rod.

After dropping the cases into the chamber, what I suspected was true.

The damaged cases are out of true around the shoulder which causes them to stick.

Of the 50 cases I am working with, I will discard 4 that are damaged.

In my experience with higher end auto-loaders, there is a break in period for both the shooter
and the gun so I am pretty confident this will work itself out with proper gas adjustment.

If the problem persists, I will purchase a Redding FL bushing die.

Thanks for the great advice Turbo.
