I've been trying to develop one for my 340 with the 250.
It has been a test will to find a load that would shoot the way I wanted. Finaly found 92.8 grain of H1000, with the col of 3.880. This makes it a single shot and it is still around .150 from lands. I am still doing drop verification, so I dont have a validated mv yet, my chrony shows 2930. This load is very warm, shows pressure at 93.5, so start low and work up.I tried sevral powders and could not find a node. imr4831,h4831sc,imr7828,ram shot mag, evan tried faster powder h4350. Targets looked like I was patering my skeet gun! With all of the weatherby freebore it was hard to get them to shoot. Most all of the powders tried showed best group, no matter how bad it still was, just below pressure singns. This is by far the most trouble I have ever had working a load for any gun!
