New best 100yd group for me (I know its not long range)
Was shot with factory Hornady 180gr Heavy Mags out of my .300 WM Ruger M77. Group was .665" with two of the shots cutting the same hole.
I'm having a lot of trouble trying to find a handload that will duplicate the speed and accuracy of these rounds. Best today was 76gr of RL22 with CCI250, behind a 180gr Partiton. First two shots were touching, but the 3rd went high and right by about 3". I think I pulled it off, but I didnt have any more with me to try it again.
I'm ordering some Hornady 180gr flat base Interlocks, like the ones that are loaded in the Heavy Mag ammo. Also going to try some RL25.
