[QUOTE="340PR, post: 1939851, member: 107814"] For what it is worth, I was fortunate enough to be on the team hired to do testing for the AMP folks. We did comprehensive and extensive testing with several different platforms and shooters. basically, we started shooting at 1000yds, recording velocity and accuracy (annealed and un-annealed). Cartridges were: 6mm (6 Shankle, and 6bra), 6.5 Creedmoor, 7mm shortmag, and 338 Lapua Mag. We also did a failure test in .308. We recorded a tremendous amount of data over a two month period (some of us continued for another two months). I think there are still some videos, and data posted on their website. It is a bit tedious to go through, but the bottom line is: There is a difference in consistency, in both velocity and accuracy. The failure test was telling, in that we had case separation at a fairly low round count on the un-annealed brass. Now, does this mean you should go out and spend $1300.00 to get an AMP machine? That is up to you. I was a fan before the testing, and still am. The consistency from round to round is there. Just like most other aspects of reloading, it is hard to beat a consistently performing primer (if you can find one), case, and powder lot. Annealing, is a major factor in consistent neck tension, which can greatly affect accuracy, and to some extent velocity. My $0.02. [/QUOTE]
