Is there anyone in the South West England offering an annealing service for brass cases? I have around 250 off 7x64 that I would like annealed. Regards MarkR

May be with dropping HRARBL a shout. He's South Devon Cornwall border.

John, many thanks for up loading the video, it looks like the whole process went smoothly. Regards MarkR

Just an update for everyone. All the brass cases have arrived safely back from John who has done an excellent job of annealing them for me for an agreed donation to the Royal British Legion.
Over the last two evenings I have full length resized all of the cases, and I have to say that the whole operation appeared to be a lot easier with the annealed cases.
I have started trimming to length and chamfering the cases, and that is also going well.
When I get around to reloading and seating the bullets, I will post an update on how that goes as well.
In the meantime I wish to thank John for offering to anneal my 7x64 brass cases for me.
Regards MarkR

Second update. Just finished reloading 50 off rounds and it was like using "new" brass for the first time. The neck tension was very good when seating the bullets, so I could easily got away without using a minor crimp that I normally use.
Overall, annealing the brass cases has injected new life into them, and I would certainly look to do it again.

I'm interested in why you feel the need to crimp at all. Your implication is that you HAD to crimp prior to annealing. That doesn't sound right to me and possibly indicates an issue with your dies?

To Crimp or not to Crimp, that is the question. Oaken, I accept that dies can cause problems with neck tension issues, so can work harden brass cases. Crimping isn't a necessary operation, it is a matter of personal preference. There is a lot of articles on the Internet about this subject, and after reading the various "what's for" and "what's against" I have personally decided to lightly crimp all of my rounds after reloading, primarily to uniform the start pressure which I understand helps produce less velocity variation which leads to better accuracy. That is simply it.

I have never seen a need to crimp in bolt guns....I believe that uniform neck tension will provide a more even release than a crimp would (no science to that comment but a squeeze...ie neck tension..... just sounds to me more likely to be consistent than a curling over of the brass?)
I have never had any bullets seat deeper or longer due to recoil even in my 338LM and I only run light neck tension.
But ...if it works for you then why not?

Ok, just sounded like your having issues. Crimping will accelerate case hardening and is an extra variable that may generate a less predictable build up of pressure..... but as Dave says, if it works for you...... :-)
