I've been making some loads for my 7mm Rem Mag with 64gr. of H-4831 powder and 139gr. Hornady SST bullets. I started with a group of 20 new cases and I'm now on my 5th re-loading for the same 20. The primer pockets are not loose,there is no visible signs of any kind of problems with the cases. Should I call it quits with these 20 7mm RM cases and start a new batch, or are these good for a few more reloadings? Thanks.

Inspect the cases for stress marks. You may also strighten out a paper clip, insert it into the case and scrape the inside of the case wall searching for an indentation above the case head that could indicate an imminent case head seperation. Other than that, keep using them. I very seldom throw brass away from too many firings. Usually it just gets stomped on or otherwise lost or damaged first!

concur with Poodleshooter.

It wouldn't hurt to measure the length of the brass, and trim if necessary. (And re-chamfer)

Brass Life

Concur with Poodleshooter and Art. I have gotten over 40 Reloads on some Brass.

My Lee manual recommends tossing the brass after the 8th firing.

Unless they have been fired with very warm loads there is no reason to toss em after 8 firings. Inspect,and if they look good, trim if needed, load and shoot them.

Annealing the case neck/shoulder area may be in order, and would increase your case life if all other factors are favorable for continued use.

The fabled "dull red in a dim room" rule results in using far more heat than needed or even wise (over-anneals 'em). Molten lead is just the right temperature--hold them mid-case, dunk in to just immerse the entire neck, and remove them just as your fingers get uncomfortably warm from the heat transfer.

Otherwise, get a hold of one of those heat crayons in the 750 degree F range.

NEVER anneal case heads. Soft brass in that area has been documented to let go in Mauser actions, with predictably disastrous results directed towards the rear.
