1:10 Twist uppers? Model1, J&T
 

I'd read where one Model1 customer recived a 1:10 barrel, My J&T is also a 1:10. I'm still waiting to see what J&T will do about this, I've had good luck with them in the past. Has anyone gotten good results with subsonic 220 grn bullets and the 1:10 twist barrel? If not, would model1 (or J&T) do anything to fix it? They said it was a 1:8 in writing, so I'm hoping that they make it right.
Thanks,

If your JT is 1x10 and they state it should of been 1x8 in writing, I'm sure they'll make it right. JT is top notch.

As pissed as I was.....
 

The 1 in 10 handled 220 RN's very well.

Any pet (subsonic) loads spook, that use either AA1680 or H4227? Do they cycle? What primer/brass combination?
Thanks,

My fave lately is 9.5 VVN 110, 9.2 of IMR4227 was ok, and the AA1680 subsonic recipe (its archived somewhere on this board) was ok as well but neither cycled reliably. However...... Bushmaster makes a screw on AK style muzzle brake that made the latter to loads cycle very well when in place. I hade to rethread my muzzle to get it to work.
