Howdy folks,

I currently have a .375 Chatfield-Taylor on it's way to me, and have done a fair bit of research on appropriate powders (seems Varget, 4064, RL15 are favoured). I have D4895 (very similar to IMR4895) which I think is a little bit faster than them, but hope will work. The only other powder I have any real supply of is H4831. I have both 300gr and 235gr bullets coming, and am hoping to come up with a 235gr load to carry while deer and bear hunting this fall.

Since it's just a necked up .338 Win Mag, I was wondering about using .338 data with the same bullet weight as a starting point? I'm assuming (which I don't really like doing with reloading) that since I'll have a bigger bore, I'd have lower pressure? Then work up with the Chrony watching velocity and for pressure signs. I'm mostly just wondering if I'm on the right track.

Thank you,

Cory
