I got a pretty good deal on a 20" AE Mk III about 9-months ago and thought I'd shoot it a while, along with my other rifles, and sell it off before I put too many rounds down it,... but I find that it's the ONLY thing I want to shoot! It just delivers. The action is awesome(!) - you can just RIP-IT and it extracts and feeds without a hitch,... unless you short-stroke it,... it's not magical. I shot a custom 260Rem I have on a Rem700 action a couple weeks ago and it felt like a rattle-can in comparison,... sloppy, hitchy, slow,... Picking up the AE right after, made me appreciate it even more,... The trigger is great as well. I have a CG Jackson trigger on that 260, and it's great, but not as great as the AE trigger. I find the AE trigger is just as smooth, but a bit more consistent in the uptake and break,... It's awesome!
Working up loads for the AE was a no-brainer. I usually do some research, find out what's working for others i.e. delivers the best consistency (temp sensitivity), accuracy, and ballistics. Then I'll pick a few bullets and powders and run some ladder tests to see what has promise. The AE didn't seem to hate anything. Everything seemed to shoot under 1-MOA. After playing around with a couple options one day, I ended up with a 0.25-0.50-MOA load that's been pretty stable for over 1200-rounds. I usually have to dink-around and tweak loads to get them shooting the way I want or eliminate pesky flyers, but the AE has been BORINGLY simple to work with and seems to be inherently accurate,... if there is such a thing (doubtful). Now, I'm thinking I'm going to sell off my 260 and rebarrel my AE in 243Win (22") - it should be perfect for matches.
