Since RL17 and IMR4350 are alleged to have very similar burn rates, I've loaded up a series using RL17 and the 250 Speer Hotcor, starting at 63 grains and going up in 1 grain increments to 68 grains.

Any opinions anyone, before I go to the range next week?

I'd imagine the 338 Winchester would have a very close capacity, perhaps a hair more, to aid in your RL-17 venture.

Judging from some of the speeds and charges with like bullets.

Getting 2,800 from 250's is gonna require a slower than normal fuel, I think.
Just like RL-22 and 25 in the 338.

Running some now in a wildcat 22; so far so good.
