Shot on a twelve-foot tall target, zero at one hundred and let the groups form where gravity takes the bullets. Moved firing position in fifty yard increments.
140 A-MAX, 58.0 Ramshot Magnum, Norma brass, Win. primer
No chronographed velocities yet, but these are right up there I believe.
Yds MOA Come-Up
200-1.25 1.25
300-3.75 3.50
350-5.0 1.25
400-6.5 1.50
450-8.0 1.50
500-10.0 2.00
550-11.5 1.50
600-13 1.50
650-14.5 1.50
Then I shot BHA 140's, excellent accuracy out to 700. Might be a very slight difference in 100 yard zero, did this with steel plates instead of the big paper target board.

Not sure what happened at 700 - only half a minute up from 650 but the rifle was shooting point of aim with 15 minutes on. Something must be wonkie there. 140's knocked the plates down at least as well as the 168 A-MAX in the .308 WIn. rifles.
Would be interested to see what some other drops are out to 700 or farther.
Thanks
