I've come to believe that 582 Minis can vary wildly when it comes to accuracy. I clearly got lucky as I got a fairly accurate one that has had zero problems.

My 582 shot about 3 to 4 moa at 100yds with irons the first time I took it to the range. I was using PMC Bronze 55gr. A lot of that lack of grouping was due to me getting used to a new rifle. Now, with the Aimpoint, I can usually keep it closer to 2 moa. Still, I think my aim is the limiting factor.

Suprisingly (to me), the by far most accurate ammo I've put through it is some frangible stuff. I was on the 50yd range with an Aimpoint red dot shooting Intl. Cartrdidge Corp. PNT 45gr polymer copper frangibles. Out of a 10 round mag of these, all but one ended up in a very ragged hole. I couldn't believe it at first, but I had someone on the spotting scope that was verifying every shot. I later read that the manufacturing process used for these allows them to make extremely uniform, symmetrical bullets when compared to jacketed ones, hence the accuracy.

Best of luck getting that thing dialed in.
