MP44, Haven't really been too concerned about ringing out the accuracy issue yet. At this point, I am getting around 3" at 50 yards, and guessing about 7" or 8" at 100 yards. I am sure I could probably bring this down. I know the 2nd range report was on a very blustery day. I don't see this as being a much over 100 yard gun for sure. I was somewhat more focused on the reliability issue.
I can now move forward with finding a good match for the gun ammo wise. I am happy it feeds hollow points and lead. Save money by making lead practice rounds, and good to know if I want to run defensive ammo through her, the gun can handle it without choking up. Don't recall if I mentioned it, but she will handle CCI Blazer aluminum cased stuff as well. I am definitely getting more of that. Has a good strong recoil impulse, so I know I am getting some performance out of that load over my reloads. Was noticeably hotter. I have to say I have not thought of Blazer ammo as particularly accurate, but that may have been the 9mm pistol I used to use the stuff out of.
Airpower, I do not find the long barrel to do anything to the balance, but I am comparing that to things like handling an M-1 carbine, not a true Sub-gun sized Sterling. All I know up to this point is rifles that have minimum 16" barrels. Seems to me the only item which would throw off "balance" is a side protruding full 34 round magazine.
And even that does not bother me. With the small round receiver, a good grasp, assisted by the textured "crinkle" finish help one get a good purchase on the rifle, or certainly as good a grasp as one needs. I pretty much just lightly craddle the forend as I shoot. Not finding much need to choke the thing.
If it was full auto, that might be a different matter!
