Bugger,

I have a ".375-06 RCBS" which is a .375 Whelen AI with a 30 degree shoulder rather than the AI's 40 degree shoulder.

I was playing around with IMR-4064 last week and loaded 50gr under a Speer 235gr SP, CCI BR-2 (what was on the bench at the time), in fire-formed Remington .30-06 brass.

Five rounds went into one ragged hole at 100 yards that was slightly wider than tall as the wind was pushing both me and the bullets around. Nice, mild load that I wished I had chronographed so I have no idea on the velocity.
