Nice shootin Tod!
If it helps you guy's, I've been using the 55gr Nosler, but in a 6mm Rem.
I have only tried one load in it which shot MOA while I sighted in the rifle. Haven't the time to play with alot of targets anymore.
I shot one yote boxing day at 310 yards while he was at a full run, broadside and hit him high in the back, entrance wound was about two inches wide, quite a mess but it hit him in the spine so no suprise. Bullet did not exit.
Later in the afternoon, another one showed up but way down the field, I guessed to be 600 yards away. I had Nugget call the shot in case I didn't see it, my three foot hold over was perfect but I hit five feet to the left. Maybe it was me but I was laying prone. I'd say there was some wind drift but it is hard to say how much crosswind there was across that kind of range.
