I finally found my old records from a couple of years ago when I have a 375x2.5

Using Bertram brass
200 gn flat Nose (.375 Win projectiles) and 41 gns ADI 2206H I got 1715fps.
and
270 gn Woodleighs and 46gn ADI 2208 (corrected) 1950 fps

Both accurate loads.

Tis was with a 24 inch barrel. I hope this helps.
