Bullet: 515 grain cast lubed.

45 grains Varget with filler .... way high .... 12"..1150FPS

50 grains Varget with filler ..... high .... 8-9".. 1250FPS

55 grains Varget with filler ..... high .... 8" .. 1380FPS

Tomorrow I'll go with the full 72 grains varget Nitro for black load stepping up 5 grains at a time. Gun feels good! Points quick, sights are excellent, no extraction problems thus far.

Gun is a engineering test mule, we're measuring all pieces of the action to determine what is failing and how to make it last longer. We're should know almost to the shot how many rounds the action can take before coming off face and shooting loose. We'll make changes to it and try again.

Normally one will see the bullet are printing higher than POA when shooting with a higher velocity bullet than the sights regulated for.....but here in this case the LOWER velocity makes the bullet print HIGHER???? Just wondering????
