My Endeavor really likes the 200 gr SW. Shot three, three shot groups to check the speed and grouping of different weights of BH 209 at 100 yards. 100 grains, .69 , 1946fps, extreme spread of 41. 110 grains, .57, 2067fps, ES of 15. 125 grains 1.02, 2200fps, Es of 5. I did not weigh these charges. I was using T C u- view measure. For my hunting load I have settled on 113 grains at 2100 fps. It is 2 and 1/4 inches high at 100, and 4 and 1/2 low at 200.
It shoots about 1 1/2 inches higher for each ten grains of powder. Exactly the same horizontal. These nine shots would make about a one inch group horizontal.
