28 nosler once fire brass help

[krhuntin]

Hello all,

I need a little help. I shoot ALOT and reload quite a bit but have been having some trouble with once fired Nosler brass fitting in my chamber. This brass was purchased online as once fired. I always resize my brass just enough to fit into my chamber with a smooth bolt close and easy extraction. With that being said, i tried to do so with the once fired brass that i had purchased. Some i can get to fit into chamber, others when i try to chamber i cannot close the bolt and the shoulder has a slight nick, then have to take a carbon fiber rod and ram down the barrel to get the bolt back. So it appears that i am not bumping shoulder back enough after .006 bump. But my die is screwed down to where i can not get any more out of the press before i break anything. Any suggestions etc? My brass that i have shot and reloaded after fireforming to my rifle shoots great etc. etc. All brass was annealed 20 minutes prior to resizing attempt. Any info is appreciated.

The problem is only with the once fired brass that was previously fired in a different chamber?

You're using the same sizing die that works well with your other brass that has only been fired in your rifle?

From here it sounds like the other rifle had a larger chamber while your rifle has a tighter chamber. Color the case with a dark color Sharpie marker & try to chamber it. You should be able to see where the interference is. If you're measuring properly, with .006" bump, it may be a diameter problem lower around the base of the case rather than the shoulder position.

It's hard to tell what the "nick" on your shoulder is all about. Can you explain? Is it there on the once fired brass? Are your dies making the mark? Is it only after chambering in your rifle? Is the mark on your other brass too? Often a picture is worth 1000 words.

Buy new factory brass.

Measure the brass that fits and the brass that doesnt.
Easy way to measure the brass in the same spot at base is to take the shell holder out of press, set on bench with case inserted and lay caliper jaws flat on top of shell holder. Then measure length using a comparator.
Can have someone mill .010 off top of shell holder if you need case to go deeper in to die

I totally understand that. But at the time there wasn’t any new brass to be had when I bought it.

I don’t know anyone that would be able to machine that for me. But I like where you are thinking.

The dent on the shoulder is from the ones that either don’t let the bolt close all the way or the ones that have a heavy bolt close and hard extraction. None of the easier chambering ones have that.

My guess without seeing it- youre bumping probably enough. Without a measurement of your fired brass to this brass its just a guess. So id bump them to what your others measure, get a small base die and get that junk out of your chamber thats denting the brass. It was probably fired in a browning. I think they use 2 layers of tape on a no go gage for their tighter ones

You might try annealing the brass, there's a chance that it is springing back after you run it through your die.

What press/die/shell holder are you using? Do you strip the bolt for chambering brass setting up your die?

Yessir. I have annealed all of them before re-sizing. Only thing I am seeing is that the brass is maybe a little bit bigger around on the stuff that won’t chamber. So I am wondering now if I am pushing the shoulder back too much and it is potentially “scrunching” the brass making it bigger around. But how would I get these brass to extend to make them longer and make it so they are not so big around? Thoughts?

So the brass is used brass you never have fired in your rifle, and the brass the bolt won't close on come out with shoulder/body damage. Brass that will chamber aren't nicked up. Have you actually fired any rounds(made from the used brass) through this rifle and is there nicked or damage to brass after firing with any brass(new or used)?

 

[Herzo]

Not knowing the specification on your die, I would suspect that it is a custom die machined to your chamber? If so, it may not sufficiently reduce the brass to account for any spring back. You may need to purchase a SAAMI specification die for the initial resizing.

Id like to know where that huge gouge is coming from- is it happening after you try to close the bolt or out of the die? Youve got something huge stuck in your die or chamber whichever is causing that. You could bump .035 and not close the bolt on something that big

The brass that fits both new and old has had no nicks on the neck after firing.

Same. I have taken apart my die and cleaned/polished and lubed it back up. Resized some brass didn’t see any nicks. Then went to try to chamber one of the tight ones and tried to close the bolt. Jacked the round out of the chamber and there is that little nick in the brass. Bore scopes the chamber and into the lands and nothing. The only difference I found in the new once fired (not through my rifle) is that the diameter of the cases is 0.003 bigger on the ones that won’t chamber. So maybe they are too big around? How would I get them skinnier?

None.

I started with my custom die. Then I decided to use the Forster full length sizing die, still with no luck. The only thing I see if the ones that don’t fit are .006” bigger in diameter. But how would I reduce that diameter?
