We I may be partial, but using an AMP and getting the brass at the correct annealing temp is well worth loosing one piece of brass. Then you can record the numbers from that test and don't have to sacrifice another piece of brass for that particular Brass/caliber.
All I hear on most posts is that the AMP has to sacrifice a piece of brass and hear shooters complaining about "ONE PIECE OF BRASS".
We NEVER HEAR about how many pieces of brass that you loose when using "Propane Flame" to get a piece of brass that we "Think" is is the right temp for the brass that is being annealed. At least with the AMP there are years of testing and results that back up the AMP and the annealing process for ANY piece of brass that is tested in the AMP to be annealed.
I know that this machine was stated too be expensive, but in relationship to what? We spend thousands of $s on Actions, Custom Chambering & Barrels, Optics, Environmental Shooting Programs-Kestrel, Accessories. Then getting into the reloading how much do we spend on Scales. Presses, Dies, Trimmers Gauges/Instruments. Then we go to the components - Best Powder, Primers, Bullets and last not least BRASS.
We all want the best of everything to make sure that we can get the most out of our rifles to make sure that they preform shooting an Elk, Deer, Hog, Bear, Prairie Dog. Coyote at extreme ranges.
So ANNEALING BRASS is an important part in the equation. I just want to say when talking about the AMP and sacrificing one piece of brass to get the equation finished isn't it worth it????
I don't think I have ever seen a post where someone is complaining about wasting or sacrificing a piece brass with Propane Flame annealing. I have used flame annealing and wasted a lot of cases and never really knew weather it was the correct temp for annealing.
However I do know that when I use the AMP to anneal my cases that they are the correct temp at the correct location of the case.
I am not affiliated with AMP, but I can tell people that I have used different types of annealing and the easiest most accurate - that I can tell, is the AMP.
Would like to hear how many pieces of brass anyone sacrifices/wastes with flame annealing. Or if every piece of brass is the correct temp for annealing every time with every different brass case you flame anneal and you never loose a piece of brass and confident that they are annealed correctly.
