Took thing 2 to the range yesterday to get sighted in for hunting season. Ammo choices are rather sparse, so for the .270Win all I could get was Browning lead free 130gr. I’d prefer to hand load but time is short, and supplies have been hard to come by for a while anyway.
Anyway, at 100 yards it seemed to be performing pretty well. Rifle is a 50’s or 60’s era JC Higgins bolt action. 1-1.5” groups without really trying all that hard. 200 yards was another matter. The other 2 center fire rifles (both CZ-550s) did fine at 200 yards. The 9.3mm was about 1.5” groups at 200. That .270 though I got like 3 shots to hit the paper out of probably 15+ rounds. I tried everything to figure where they were going. The target boards were large enough for 3 targets across with 2 rows. I aimed at the top of the board, bottom of the board, left column, right column, dead center between the 2 middle targets, etc just to see where the rounds were going. Went back to 100 yards and the bullets were hitting basically POA. Back to 200, no holes in the paper again. Did that a couple times. Shot the other rifles at 100 and 200 with good predicable groups. Back to the .270 and still couldn’t find holes.
Could the bullets be keyholing between 100 and 200 yards? The 3 holes I did find didn’t look at all like the bullets were keyholing. What else could cause that? Didn’t have a chronograph but based on felt recoil I’d believe 3000fps (3100fps advertised on the box).
