Does anyone own or have experience of the SAM annealing machine, I don't seem to be able to fine reviews etc.
Annealing
- Thread starter YoungCurrie
- Start date
There's some videos on youtube and that's about it . I contacted the guy who produces them and they were about €900 at the time , if my memory serves me , without the auto feed . That was the price without import fees/vat .
They certainly look the business.

Thanks for that, they do seem a bit pricy compared to 'gas'.

I know nothing about the SAM annealing machine.
However, during Lockdown I, I bought an AMP Annealing machine.
I am yet to use it.
If you have brass that needs annealing, send the damn things to me and I will at least get to use the shagging machine...
Seriously...

Thank you very much , I may take you up on that.

If you're not carefully everyone will ! Be prepared for a full inbox .
Is that…like…one of those….erm….open offers?I know nothing about the SAM annealing machine.

I’ve got an AMP. Not cheap, but a dream to setup and use
Case separation , is most commonly associated with excessive headspace , created by pushing the shoulder back to far during sizing.

Yes, I‘m aware of this.
Non the less, I had to dump a batch of Norma .270 Win. cases due to case head separation after 10 reloadings, 8 of which involved neck sizing only. No big deal really as the .270 is a different breed than a .308, but still, I‘m curious.
My apologies , no, would be the answer .
Did you find the brass for your . 270 required a lot of trimming . I never reloaded that much for the 270 , just wondering if the brass flowed a lot due to the shallow(ish) shoulder angle? Just a question out of curiosity , as it may have contributed to the case thinning and stretching .
I'm sure someone will be along to give you a definitive answer

Case stretching is indeed an issue with the .270. I keep records of what I I do with my cases, but only as lang as they‘re in use. Thus I no longer have it available. But from memory trimming was in order every third reloading.My apologies , no, would be the answer .

Your consideration does make sense!
It was just a thought , might be worth starting a thread as to the expected life of brass in various chamberings.
Who knows , 8 to 10 for the .270 may be exceptional ?
Regards
P.S . I would do it if it weren't for my crippling laziness.

I trim every fifth or so firing. But then, I load my .270 fairly soft at around 2800fps so the brass doesn't have quite as hard a time as if I was up at 3000 or so
Done properly, annealing only affects the hardness of the brass at the neck and shoulder.
The main body of the case should be unaffected.

Or build your own for about £150. Plenty of vids on you tube and parts available on Amazon !
I've annealed over 1500 cases with my home made induction annealer and I'm now getting enough data to reach an interesting conclusion,
These have been a mix of 22-250, 243 6.5 Creedmor, 260 REM and 308, from a wide range of manufacturers including Lapua, Norma, Sako, RWS, PPU, Geco, Hornady, Federal Remington and Winchester.
What I have found is that the brass from all the European manufacturers takes significantly longer to anneal than the brass from the US manufacturers.
Because of differences in the heating coil, no two induction annealers will have the same annealing times, so the following times apply only to my particular set up
For European brass in all the sizes listed above, the annealing time is 9-10 seconds
For the US brass in all the sizes above, the annealing time is 6-6.5 seconds
In other words (and this has happened) if a batch of Lapua 6.5 Creedmor brass happens to contain a Hornady case and it's not detected, then that case will melt when it's annealed.
