6.5 Creedmoor casings-can't seem to fully resize them

[golfer2b2000]

I recently purchased some once fired Norma brass in 6.5 Creedmoor. I figured that I would just resize them and load them for the field. After resizing to the full extent of the resizing die, the brass will still not fit at all into the rifle.
So what is going on here?
Do they make a small base resizing die to take care of this issue.
I have new brass that fits easily.
Somehow I need to get these brass down to where they fit.
Any ideas on how to solve this issue?
Thanks!!

Mark a case with a sharpie and try to chamber it. Remove it and you will see where it is rubbing and causing the issue.

The only one I know of is in an RCBS kit, 32907. But I'll warn you, it really sizes the brass a lot, all over, not just at the (small) base.

Sharpie it up and see what dimension is causing you issues. If you're in need of a ring die (only sizes the base), let me know, I have an extra from PBike.

real amateur advise here, but I would measure the cases that fit and compare. what full length resizing die are you using? much more experienced people reading this than I.

You might have to trim your shell holder.

A small base die should take care of it. I've run into this with once fired brass for 6CM. It was probably formed to an AR chamber, or at least a chamber larger than yours. Most dies don't size all the way down towards the head...and I bet that's where yours is catching.

My advice. Never ever use brass fired in a different chamber.

After the sharpie .... measure at the 'scuff ' then measure brass that will fit and see how much difference there is. JMO

Agree 100 %

First find why and then determine how to solve the problem.

By now you know what you need to do, Mr. Sharpie is your friend!

When you say, "to the full extent of the resizing die", what do you mean? How are you setting up the die?

 

[NZ_Fclass]

Does the fired brass fit into the chamber without resizing? You may have a dodgy chamber - ie not round. Check your fired brass-it should fit back in in any orientation. I

Excellent advice.

 

[Walt Krafft]

Check over all length. It may need to be trimmed.

What going on here you asked? The cases were fired in a substantially dimensionally different rifle chamber than yours.

Is it worth trying to chase a fix? I learned the hard way a long time ago to always start with virgin cases for precision rifle reloading and shooting.

^^^^^^^ What he said.

Same thing happened to me. I had a barrel that the jump (lead) was too far out but the rifling was still good (had about 900 rounds on it) Had it cut back and re reamed for my 6mm Creedmoor. After shooting about 20 rounds and then trying to reload the brass I could not get the brass 3/4 of the way into the sizing die.

Did some measuring of the brass and found it was .04" larger at the base of the brass than my other non reloaded brass.

Took the barrel off the receiver and stuck a new case into the chamber. I could wiggle the case in the chamber side to side.

Went back to the gunsmith and he checked it out and told me the chamber was wrong.

He gave me a new barrel and reamed it out.

All problems went away.

I had to toss the larder brass out because there was no way I could resize them.

I think I'm just going to trash this lot of brass and just purchase virgin brass and go from there.
Seems like the most logical thing to do.

Excellent plan!

There are enough things that can go sideways in precision reloading / shooting, you don't need to add to them by using once fire brass from unknown sources.

new brass, no problems
