Nice. Was the case full at 43gr?

It filled up a to the bottom of the neck. I loaded some at 44g with the 60gHH. Those loads were half way up the neck.
I didn't report them because I didn't get velocities.

Loaded a few at 46, they shoot around .75 or so. This is primarily a loaner/wife/kid rifle for shots inside 400. Still over 2200 at 400- ought to work very well, and recoil is very pleasant.

Guys, this was a throw together load, that was recommended by another member here, I'm sure. Directly out of the box, it shot the last two into the same hole. The ones before it were sighters and adjustments . I'll try to attach a pic if it will let me. Velocity unknown, but very reasonably estimated to be at around 3550. This isn't my first experience like this either.
