Problem with bought "once fired" cases

[CROWMAN]

Thanks for all replies.

I have successfully re-sized one of the cases, but only by taking my R.C.B.S. full length sizing die down to about as far as the thread will go.

As I said initially, I have re-sized many once fired cases and perhaps about a half turn decrease was required, what rifle chamber this came out of god only knows!

I thought that it must be something else that was causing the problem.

Hopefully I will be able to re-size successfully the rest of the batch, one thing with buying "once fired" cases etc is that you need to run every sized case through your rifle chamber to make sure all is ok or risk a possible jammed round at the range.

yes i would personally check each case to see if it chambers....once done you can resize as normal when fired in your rifle.

i have a lyman orange crusher press with removable insert at the top so i can use the big martini henry dies which are 1 1/4 rather than 7/8ths etc.
i couldnt resize the brass unless i took off the die lock ring and screw the die fully down until it was nearly out.
the press ram basically was too short.
i had to piggy back weld 2 shell holders together to raise the case far enough to work properly...... i know you can buy extender shell holders now.
the issue is the top frame of the press is too thick to allow proper seating of the die.
that was a pain to sort out but got there in the end......was many years ago though.
not saying your press is wrong but sometimes simple things go wrong.......

i have 2 big orange crusher presses and both identical.......only one over cams and the other doesnt, didnt realise their made 2 types

Is it possible they need annealing? Once sized do they feel as there is no more resistance if you do it again. Brass might be springing back a little once done. Annealing will take the stress out of it. Interested to know if anybody agrees with me.

no but its good practice to regular anneal your cases.
i dont with my common calibres but i do with the martini henry 577/450 at £7.00 a case.....every 3rd firing

I thought that I had solved the problem but after trying more this morning, no good.

I have tried rounds which I have reloaded using previously fired cases from my rifle, all ok, so I assume no problem with bolt etc.

The press is a R.C.B.S. and no obvious problem with it as I have used it for reloading three different calibres.

The cases I bought as "once fired" are I think "once fired" and were from "bought" ammunition, one lot Norma and the other Winchester, so it's not case specific.

The thing that I do not understand is that I have reloaded Winchester "bought" cases from a friend who is a fox shooter, so only "once fired" and they have reloaded and fired without any problem for him.

I have taken my full length sizing die (which is a Lee and not a R.C.B.S as I previously wrote in a earlier thread) down by turns until I have run out of die thread. Still no good.

Is it the same type of problem that "Loiner" wrote about in an earlier thread?

I'm stumped and any ideas would be welcomed.

Just thought of one thing which I meant to do but haven't , I have not measured the overall case length, I'll do that now but have never cut to length the cases before resizing before and all have been ok.
