Been working on this load on and off for my best friend for awhile. We shot this load at 2.900 COAL quite a few times. He's running 3130 with RL19, CCI250, WW cases and is shooting them out of a nice little M70 Extreme Weather.

The last time out we kept getting a 3rd round flier..







Occasionally we'd get a great group like this..



Decided to shorten them up .010" at a time and see if we could pull that 3rd shot in.. I think we found a node where it likes them now...

This was at 2.890" COAL



2.880" COAL



Once we pushed deeper, they started scattering again. It was a good lesson for me. Don't settle for one little group, your load could be sitting on the edge of a node where it really wants to shoot, but it'll fall in and out of it..

Pretty happy it's shooting very well between 2.880 and 2.890.. Gives us a little flexibility..
 
Good work Scotty.
You shooting at 200 yds?

That is fine work and superb riflery. Of course, we'd expect nothing less from a Marine. Good job.
