In my rebarreled 270 WSM with a 7 1/2 twist, I shoot the 165 ABLR. I sight in at 200 yards getting 3/4” groups. No other bullet has come close to this accuracy. The best I can get with the 150 ABLR is 1 1/2” group no matter how hard I try. Some guns love certain bullets and others not so much. I shoot this 270 WSM at a 1000 yards. On a nice day my 5 shot groups are 6” with a velocity of over 1600 fps. I love this bullet, have not found any but this one box. Been looking for 6 months, so saving the last 40 bullets for my deer hunts.
