OK, some history here: I bought a TNW 10 mm PCC first. Recoil was mild; accuracy was decent but it jammed ALOT. It was very unreliable. When it did cycle, it only tossed brass about 6 ft (which was good). I spent hundreds at the local gunsmith trying to work out the kinks but finally gave up.
So, I ditched that one and bought a blowback AR in 10 mm from Pro2a. Accuracy is good and reliability is good too (in it's original configuration. However, it throws brass 30 yards hard enough to dent the brass as it hits the deflector. It came with a "heavy duty spring" and a 10 ounce buffer. the bcg is 14.5 oz so total reciprocating mass is 24.5 oz. The recoil is more jarring than that of the TNW too.
Things I have tried: I bought the strongest spring I could find (springco orange spring). Maybe a little better but very little if any. It still tosses brass into low orbit and dents the brass. I think the bolt is outrunning the magazine now though so it started jamming. I may need to go back to the original spring. If I could find a significantly heavier buffer, I would try that. I did find a 12.5 oz buffer available but it is $130 and I am not quite that desperate yet. I thought about taking the tungsten weights out of the buffer and filling with tungsten powder but I don't really know if I could get more mass that way. There is some wasted volume around the tungsten weights that would be filled but the space between the tungsten particles makes it have an apparent density of about 12 g/cc instead of the 19.3 g/cc of a block of tungsten metal (read that on the description of 300 mesh W powder on Amazon).
Any ideas on how to tame this beast? More mass would be awesome but I can't find a heavier bcg or an affordable heavier buffer. Everything is designed for 9 mm and 10 mm is a LOT stouter.
