Annealing 45Colt?

[FortHunter]

Was wondering if anyone here bothers to anneal 45colt for SAA revolvers. I got some red bag Winchester thats on 8 firings and I had a few necks start to split. I would just be annealing with a butane torch and eyeballing it. Not going to spend on a annealer just yet, and definitely not for pistol brass.

My questions are

1. Will annealing straight walled cases help prevent cracks from starting?

2. Is it too late for the brass lots that are 8x fired or would I be able to squeeze some more firings out of them?

More details: Winchester brass, Campro 250 plated projectiles with smokeless powder (win231)

Thanks.

I load the same bullets (with Titegroup) and have thought about this as well as I already anneal rifle brass.
I don't shoot my 45C all that much, but I don't see how annealing wouldn't benefit.

As for the 8x fired, that might be a bit too much but is doesn't hurt to try.

I have tried it with low pressure loads. Brass was too hard and wouldn’t expand with low pressure. Cases were cover in burnt powder. After annealing the cases stayed cleaner. I also believe that it increased my case life. Two anneals and over 20 firings. Even pistol isn’t cheap anymore so I try making it last as long as possible.

Guess ill split the remaining brass, one half will get annealled going forward and the other set won't. See what lasts longer.

I just annealed a bunch of 45 colt brass the other day
Some were starting to split at the ends and before I annealed them I trimmed them and to my surprise a bunch of them needed to be trimmed as they were a bit long
I do think that annealing helps I use the ags annealer

I must of overannealed the brass or something. Just about 10% of the anealled cases turned out like the 4 on the left. One on the right is same lot 9xF never been annealed. No change to the die set up for the brass that wasn't annealed and everything worked fine. I annealed each brass for "2 Mississippis" with a torch. Going to toss the brass after firing the good ones, ordered some starline from budget.

Yes, clearly you reduced the strength below what is necessary for the case to do its job. That's interesting, I've generally held that it's not really possible to 'overanneal' short of actually melting the brass. Clearly there are exceptions. I've observed that 30-30 cases will suffer collapsed shoulders if annealed the same way as more modern bottleneck cases typically are, I guess this is another example.

Maybe a little too much heat, but shooting them will harden the cases a bit and good to keep them going. Throw them in a tumbler and the case will look like new.
