Cracked neck

That looks like garbage brass to me, yup, the bottom says Winchester. ;)


My annealing effectively triples the brass life, so, yes, I feel it is worth it.
Going on round twelve with some, allegedly soft headed, Federal brass in my 5.56 AR.:thumbup:

I’ll probably toss them soon because the extraction groove is getting chewed up. I’m not about to file case heads to get them to fit a shell holder…
I don't understand the Federal hate. It's swift brass. Soft brass lasts a long time if you don't blow out primer pockets.
 
I tumble my brass to get it clean, anneal case neck & shoulder with propane torch, battery drill & socket, lube and resize using small base RCBS X-die -- trim once and forget. I no longer have cracked necks, no need to trim anymore, and anneal again after 3rd firing. RCBS X-die and annealing ended my brass problems.

I cannot confirm that my process is perfect or correct, but it ended my brass cracking issues. Under annealing causes resizing to need more force on press handle. Annealed case body, not the base was not a problem. I shoot mid-range loads in my center fire rifle calibers.
 
Thanks for all the good information. This is a great place to learn. I was pretty sure that there were no pressure issues, but it’s good to have that confirmed, or that there wasn’t something else unsafe going on. I’ve never annealed my brass, but I may start looking into it.
 
Thats the exact reason that I bought an annealing machine. Winchesters QC really got bad back during the last shortage. I was getting a high % of split necks on the first firing.
