Thinking of going the whole hog with annealing and was wondering who out there has been down the road of looking and buying a setup.
I under stand that if its not done perfectly it can do more harm than good so looking for some input
Cheers Andy

Pedants put too much emphasis on getting annealing perfect down to the last 5 thou below the neck or shoulder, truth is as long as every bit of brass is done the same then they will give identical performance.
You can anneal the neck only for neck tension and brass longevity reasons or include the shoulder for fire forming and concentricity improvements
I have seen some Lapua, Bertram and federal brass annealed half its length, which I think is going a bit too far.
Are you annealing yours 7mm and if so whats your rig?Quote:

They are very easy to make.
The big RUM and Lapua cases are a bitch to anneal as they like to jam in the exit due to their length.
Some guys can anneal effectively holding the cases by hand.
easy to do by hand the mistake most people make is getting the case too hot ... rotate it and dont go past blue in colour then drop in warm water to quench
I can build a pretty good fence but my engineering work has been labeled agricultural at best so that's why i was thinking of buying one instead of making one.Quote:

Same principal with dished lower but had skateboard grip tape on it.
Got lost somewhere in the olds move - sure its laying around somewhere but 'where' is more to the point
Sounds like there would be enough interest, for some-one who had the necessary machinery/tools and skill to do a run of them, and sell them to members maybe? I know I would be keen - doesn't matter what it looks like it just needs to work.
Cant have a beautifully looking machine and then have an ogre like me working it eh:)

Would it be worth it to have a "caretaker" own one on behalf of the forum to do members brass in batches? Bit like the chronograph and lapping bar?
Maybe a koha to the forum per run for the actual cost plus a bit on the side for the caretaker? Courier bags are cheap.
