So far I've found that Lawton, McGowen, and PacNor will make a 1-10" twist .375 barrel. I imagine that Benchmark can as well, but I've decided to try a different maker. Nothing wrong with Benchmark (I have one already and a second one which should be done in a few weeks), I just want to try some other companies. Are there any other's that you guys can think of?

Pac-Nor will also make a .375 with a 1 in 8 for long heavies...

It's going to be sort of a 375 Super Ultra mag. I should have the final reamer prints sitting on my fax machine when I get home. I went with a 40* shoulder pushed forward about .175", reduced body taper by about 25%, and extended the lead in the throat to .406". This lets me seat a 350gr Match King to an OAL of 4.100" at the lands.
I don't know what velocities I'll get but I'd be pretty happy with the 350s at 2800 fps from a 30" barrel.
