IMO this is getting into a level of complexity that is unnecessary.
To confuse everyone further I am attaching a paper below about annealing.
Gee............Thanks Joe.......

Don't believe everything you read in a book or the internet. The environmental's make a much bigger difference than 1/8th MoA, but every little bit helps when major championships are decided on X count in many cases. FC X ring at 1k = 5". 1/8MoA =1.25" or 25% of the X ring and that applies to both elev and windage. Keep in mind the scoring rings are widest at 3 to 9. Every little bit helps!Most of the books I've read, stress the point that trying to turn 1/4 MOA ammo into 1/8 MOA ammo is a waste of time because the environmentals make far more difference on where the bullet goes.

Coolhand – I’ve read the test before when we had a thread on this board months ago and I have looked at it again. There is absolutely NO indication to me that the test are fabricated/ or is BS and if you read my post above carefully, I have never said such a thing. The unit works and works well as far as I can see but the point here is does it work SIGNIFICANTLY BETTER than the traditional annealer, and work better to justify a 2x cost plus having to put up with having to put in each case by hand.
If you can see anywhere where an objective test was done that clearly and statistically show that the AMP is superior to a propane annealer (which is what I was trying to debunk in my post), I would love to see it. Please show us!
As to the fact that ANY annealer can produce a perfect anneal regardless of how it is done, let me show you why it CANNOT be done. I have a BenchSource annealer and I love it, but I can tell you that it too cannot do this – why?
The reason is simple, because there is two sides to an anneal, the machine and the brass. Unfortunately regardless of how good the annealer is, the brass we use is not consistent. Weight your brass and notice that even with Lapua, the weight is inconsistent. Inconsistent weight means some cases have more brass in it than others. More brass means more annealing time to get to a specific anneal and so if your case brass content is inconsistent, the annealer no matter how good cannot fix this.
I buy Lapua cases by the 500 count and weight sort them so that each batch I use is less than 1 grain different but that only decrease the problem not fix it. Even AMP clearly acknowledge this since they have different program setting for different makes of brass but their number does not take into account variation within manufacturer which we 100% know exists.
If you use a ball micrometer and measure neck thickness, yes even Lapua will have variation and this affects the anneal for the above reason. One may argue that one can turn the neck – true, but how does that fix the brass content variation at the shoulders?
What I am saying is all the expensive annealers (AMP, BenchSource, etc) out there are indeed very good and I would never anneal without them. But the idea that one is significantly better than the other keeping in mind what we call “noise” listed above exists, the fact that the AMP annealer is significantly better has NEVER been proven – That’s the point.

keep in mind that the OP never started off saying it produced better groups just a bunch of positives about its use in the environment - which interestingly are negatives associated with gas that have me looking at the AMP as well. There is a lot of information that is never empirically proven with respect to group size, often just a bunch of people saying - 'works for me'.
It might be twice the price to you but have you tried to get a benchsource into another country - twice the price is cheap.
I'm very pleased that there is choice out there and those that are happy with their gas annealers - well keep having at it, you're happy; just remember there is more to equipment selection than 'does it make groups smaller'.
I thank the OP and this site for the review - it greatly helps with making purchases
Exactly! That's what I was looking for. Not bashing AMP in any sense, just want some real evidence for that 2x cost.jlow...I'm still waiting for the on target proof that the AMP is superior as others claim.
Annealing is anneaing...how you get there is personal preference.
Don't get me wrong...AMP is nice and anneals brass. Pricy, yes...but what new technology isn't?
On target advantage of AMP better, i don't see it. Id take my chances with 3 new barrel blanks and find the best shooting one..
do you have empirical evidence (on target) for hand annealing vs a benchsource?Exactly! That's what I was looking for. Not bashing AMP in any sense, just want some real evidence for that 2x cost.
Good point, but the reality is I am not trying selling a BenchSource as a product, if I was and want to claim that it was so much superior than hand annealing, I would need to do so.do you have empirical evidence (on target) for hand annealing vs a benchsource?
I personally have no problem with the material in the OP, but if you actually read the rest of the thread, you will see people who starts to claim that propane annealing does not do anything for accuracy but basically the AMP does.
If living down under means you can get the AMP for a good price relative to the BenchSource, knock yourself out, I’ve got no problem with that, just not the same for us.
Jlow , propane works fine but I saw a better mousetrap and decided to invest, with the help of a buddy to go halves. Now I can't refute or confirm the statements that have been made that AMP does but others do not improve accuracy but it would seem that an awful lot of people have invested in an AMP, I do however intend to find out for myself.
And despite being down under I still had to pay in US Dollars and the freight to me was $20.00 more that to the US. AMP emailed this morning my unit shipped out today. Its only 3 hrs flying from NZ so maybe I might have it by Friday.
The reason I decided for the AMP, is logistics , apartment living is not conducive to open flame annealing. I built two propane units which worked exceptionally well, I gave one to my Gunsmith and sold the other to recover the cost of components. Now I don't have to pack up my kit and go find somewhere to open flame anneal.

I'd imagine for guys set up to anneal, with whatever, buying this machine gets into a diminishing return thing for the money. I can see a lot of newer shooters buying it, and rightfully so, looks like they've done their homework in hardness tests.
When I first saw this machine advertised, it didn't have the capability to anneal the cases I shoot, but with software upgrades, it's getting better by the day. It's a matter of time before I own one, lol.
Train them well, those cases are pretty darn hot when they are taken out. I did a test on thatYeah agreed - one huge advantage that I am keen on is the kids can now do my annealing, my time has gone from several seconds to zero![]()
Train them well, those cases are pretty darn hot when they are taken out. I did a test on that![]()
Gundogs and children ..... a little pain applied at the APPROPRIATE time works marvels !Train them well, those cases are pretty darn hot when they are taken out. I did a test on that![]()
Oh no... not another temptation.![]()
