I acquired a new Remington 700 in .375 H&H that was built by a guy named Frank Wells out of AZ. My dad picked it up in an estate sale and didn't really need/want it so I got it from him. It has a Douglas sporter barrel, action was blue printed and trued by Frank Wells, polished factory trigger, McMillan Mtn. Rifle stock, and a Leupold VXIII 1.5-5x20. I am looking to do some reloading for it start with some 250gr. Game Kings but thought I would pull from the wisdom here first. If you have any load work that you'd be willing to share, please let me know. I have only loaded up to my 7mag so am not sure on the bigger caliber stuff. Thanks a ton!
The 375 is a great little round. I've had one in my gun cabinet for years. I like rl15, 4350, and I 4320 for it but other powders work well too. Just think of it like a big bore 308/06 powder selection wise and you will do well. I've got a lightweight rem700 with a factory bbl. and a 6x Nikon on top.
My current load is the 300 tsx with 70.0 I 4320 in rem brass with a mag primer. 2550 fps and moa at 100.
I also use the 300 dgs with 78 I 4350 and a mag primer.
The 260 nos ab sings well on 72.0 I 4320, so I suppose the 250 sierra would do similar.
Expect 2800 fps or so on mid weight pills (250'ish) in this cal, and 2600 fps or so with 300's.
