I got out and did some testing with my rem 40x this weekend. I tried out the norma tac22 ammo. It shoots really well in this rifle. I zeroed at 50 yds. shot at 100 and 200. I ran the scope up and down several times to test tracking while doing this to verify return to zero and return to same evevation at range. I also chrono'd using the magneto speed prior to shooting the groups so it was not attached when gathering dope.
50yd=zero, 100yd=4.125moa, 200yd=19.125moa. this is on a mueller 8-32x40 scope.
temp 70deg, D.A. 7000, velocity 1130fps, 40gr bullet, bullet BC guestimate .134 from rimfire central. I run it thru jbm ballistics and am way off. I have tried varing altitude, bc, velocity and am still not close.
Can someone spot what I am missing.
also shot blazer 22lr while there. 1249fps, 40gr, 100yd=2.625moa, 200yd=16.375moa, zero was not changed from norma ammo. the blazer hit about .500 higher at 50yds than the norma
magneto speed was set to rimfire settings before chronoing
i am in colorado shooting at the CRC range. I dont know the actual elevation there but DA was in the 6900-7100 range when shooting these groups
