Anyone shooting a 30-378 with heavy bullets?

[Sgt. Brumbaugh]

I am going to finally start messing with a 30-378 I built a couple of years ago.

.333 neck
Hall G action
34 in. 3/3 Pac-nor barrell, 1.35 no taper.
Jewell trigger.

I am going to start with 240SMK and hope to try some heavy Bergers when / if they become availibles.

Anyone shoot a similar set up, what powders and how much gave good results? Looking for a good place to start.

Thanks,
John
