Running 75eldm from an 18" 22cm. Loads sub moa at 400y. Running 3100fps. Shot two mulies this morning. First was medium body buck at 275(2600fps impact), in the crease, did a 50y death sprint and piled up, massive lung trauma, deer bleed out profusely from the mouth before I got to him, no blood as I cut neck, it was all in the boiler room and on ground. Nickel entrance through a rib, exit was quarter size throug a rib. Next was another medium body buck, 475y(2250fps impact), strong crosswind, but my nephew who's never killed a deer, put the bullet at the neck shoulder junction, pencil entrance, quarter exit. That deer was lights out. I was impressed. I have quite a lot of the 77s as well, and may try some. This load is no pressure, and is only 40gr H4350 I feel another 150fps is on the table. I only have 65 rounds down the pipe.
