The nosler 8 says it will of course it says the 142 was tested with a 1 in 9. I question that as the 142 ABLR is longer than the 127 LRX and it would not stabilize in my 1 in 9 at sea level. The 127 lrx is 1.397 long and the 129 ABLR is 1.368.

I would think the 129 will be fine.

Check out bergers stability calculator I could not get it to paste it says 1 in 8 recommended. Reality is always different. My 1 in 9 6.5-06 will stabilize the 140 VLD which berger does not recommend.

Good luck and shoot straight
