Jeff,
Closest thing I had to what you have, was a 338/06.
But I can pass on that 50 grains of 4064, with a 200 to 250 grain bullet will yield an MV of 2500 fps out of a 24 inch model 70 barrel., with close the same point of impact.
For velocity, H 380 was to top of the bell curve. you can't get enough in to exceed SAAMI specs.
it is accurate as hell also....200 to 250 grain bullets. 2900+ for the 200s, 2800 for the 225s and 2650 for the 250 grainers.
Liked the latter with a 250 grain RN....it just looks old school cool.. especially with a necked up nickel 06 case.
