[QUOTE="ERH, post: 2726309, member: 34517"] I bought a new Browning X-Bolt "Speed" in 7mm Rem. Mag. with 1:9.5 twist for moose hunting in Newfoundland. In hind sight, I would have preferred a 1:8.5 or 1:9 twist as these stabilize heavier bullets better. But did not want to pay for a custom rifle. However, I found the 7mm Nosler 168g ABLR and 175g ABLR stabilize in my rifle. Some Ballistic sources eg. Litz say they are stable under a 9.7 twist. My three shot groups are near MOA in my rifle with H4831sc, IMR 4831 and RL 22 (what I have in my cupboard) powder at max or near max loads ..so far. My best load so far for 168g ABLR is 64g MOA Max Load with IMR 4831. Working up this load looking for pressure signs is wise. I chrono'd these at an average 3 shot group at 3005 fps with a 13 fps extreme spread. At 500 yards the 168g bullet arrives with over 2000 ft-lbs moose killing energy and is still clocking 2334 fps. I will shoot some in a few weeks at 300 yards for zero. Stay tuned. My son has some H1000 I may also try. I am not a fan of the trigger but otherwise really like the rifles 60 degree bolt and 26 inch bronze cerakote barrel. It shoot sub MOA 140 grain AccuBonds. [/QUOTE]
