Not chrono'd. It's a 1:8 twist so I can shoot the 165/170/175 gr bullets. Not a "hot" load by any means- 56.6 gr w/H4831 sc. Accuracy was good after 6 rounds so I just loaded up thr rest there due to $$$. I didn't figure this for a very long range bullet anyway, but the BC is pretty good at .590 they Cuttin Edge claims they will function don to 1500 fps I believe.
I think in the OP it was stated it was only going to be for 300 yds and under. If that is it, hard to beat the TSX,TTSX,LRX.
Depending on where you live you may be able to stabilize them (elevation). They are super long though. I am at sea level here in Cali so no joy.
