I tried the 311-247 RG back in the day. Pretty sure NOE 311-242-HP is the new name. Guess I don't know if you were interested in that hollowpoint version.

Anyway, my 8.3" rifle functions flawlessly with 9.5gr IMR 4227 and all the common heavy bullets typical for subs. I had nothing but trouble getting that bullet to feed reliably. Seemed it wanted to be longer, where that 9.5gr IMR 4227 seemed too slow. More powder, more noise. I found a spot at 9.6gr IMR 4227 and 2.085" OAL where it seemed to feed, but only at 986fps. 0.005" OAL shorter and it would flip up into the barrel extension. Longer and the velocity fell off more than I wanted.

There are some threads on this forum. they probably show up under the old name 311-247. I've been looking / lurking, hoping someone to post some new info. I've given up on the bullet. Just too finnicky for me.
