Looks like Aim is cheaper, but Gunn mentions in some threads here about a discount. what is the actual story?
AIM is one of master distributors,we offer great pricing direct but they are typically a bit better. If you call us you can talk directly to our staff to learn more on our work. Possibly even make a recommendation to help us with AAC's fantastic cartridge.

You wouldn't happen to know how much powder is being used and the fps from your 130gr rounds? Seems like a good selling point.

Thank you.

I noticed your Osprey has the tube bowing out from the piston assy.. I had never really looked at it before, but after shooting some 240 gr Subs from my 44 spl I noticed that the "tube" is not flush with the piston assy housing.

I FREAKED OUT.. was my load to hot??? It;s only 4.2 gr American select from a 8" barrel it has less MP then my 45 ACP loads. I also shot some 200 gr 5.2 gr loads and (I use for Cowboy action) and thought maybe they hurt it.

Anyone have this and maybe it was like this all along and I never really noticed it.

BUT it looks like the tube is starting to "round" (which over pressure would absolutely do)

I shoot all my BLK out of my Mystic supers and subs w/o any problems. Was just starting to worry.. I really LOVE it on my T/C

john I am not sure what area you are talking about, if you mean where the barrel goes into the suppressor, the only part of the suppressor that is showing is silver in color, the rounded part is actually part of the barrel. I havent seen anything that is "bowed" out.

Look at the wing tip... then go about .2" twards the booster assembly (the registered part) .. See the seam line. It should be flush not .02" off the plane of the side of the booster. Run you finger from the booster to the tube and you will feel where the tube is starting to bow SLIGHTLY. Mine USED to be flush.. now is out .02" I fear the constant hammering of the expanding gasses will continue to move the tubing farther.

A Cylinder would resist this .. You can see it in my picture as well at the one on the Micro7 Maybe a full power round by accident?

The MOST I have put through mine was 5.5 gr of American select in a 44 Mag case out of a 9" barrel.. But that should be about the same as a 45 ACP or less. So I don;t get it. Maybe those HOT Wolf 45 auto rounds I had (FLAT FLAT cratered primers) did mine? Of just the round count?

But it has me concerned. Or I am not remembering correctly and it was this way from the get go .. but when I measure the "Flat" where the eagle logo is it is not FLAT anymore but has a curve in it now.

Which is what AAC has been saying all along. A cylinder is better at resisting pressure.
