I own a 375 Winchester BB lever action rifle. I love to shoot it at ranges no more than 150 yards. I reload and use 240 cast lead bullets. My problem is that the only gunpowder I can get is the 800X. Anyone can give me advice on the possibility of using such reloads. I shoot and hunt at short range; between 50 and 150 yards.

I looked through my load manuals for you and saw no reference to 800X at all in the good 375 Winchester.

I expect that you have allready searched the web (because you posted here), so I won't bother to do that.

I could "guess" at a start load for that combination, but I won't on the internet for your safety as well as others. Published data is the best way to go vs someone you don't know in Iowa.

I wish you well in your search.

Data for 800X in 375 Win

CHEEZYWAN

Thank You very much for the effort, I also checked manuals with no results. But a few years ago, I experimented with different loads and bullet weights. recently I found between my records some notes and targets that contain the information. As You mentioned, to avoid misinformation that could cause trouble to someone else I abstain from listing the loads and the results.

At the time the only propellant I could find was 800X. Now fortunately I have a provision of gunpowders listed in manuals.

Thank You again.

I shoot IMR 800X in the 32 S&W Long and the 32 H&R Magnum but I have not thought of shooting it in the 375 Winchester. Even Greg Mushial did not shoot it - you can bet he didn’t think of it or he would have.
Greg shot the 240-grain cast bullets in his 375 Winchester. I shoot the 250-grain Lee bullet as my plinker.

With the Lee bullet, I shoot 2.8 grains of Alliant Bullseye and get 550 fps from my 20” barrel.
3.0 grains of Bullseye gives me 630 fps.

With Accurate Arms No. 2 6.5 grains gives me 975 fps.
6.8 grains of AA No. 2 gives me 995 fps.
7.0 grains is a maximum load for me with AA No. 2 and this tops 1,000 fps.

We are jut starting our hunting season but if I set down to load anything I’ll look at 800X. For these large flakes, I prefer the electronic powder dispenser as it throws a uniform charge.

Do you run into many 375 Winchester shooters down there?

Years ago I had a Winchester 94 Big Bore in .375 Winchester. I absolutely loved the 250 grain factory load. When they got hard to find I went to the 220 grain Hornady .375 caliber rnfp and used Reloader #7 powder. After that, I never used anything but Reloader #7, it just did everything well in the .375 WCF.

Sincerely,
Dave (Bubba) Thornblom

I have used Unique in my .375 Winchester with RCBS 265 grain cast with gas check. As I recall I got the load data from the old Lyman book (perhaps for the .38-55) If you can find a start load for Unique, then you would have a starting load for 800-x which is a slower burning powder.

As far as I know, in my shooting club only two of us have this wonderful 375 BB. I have dropped game from rats to the impressive Tapir called here in Venezuela "Danta" with one shot at no more than a 100 yards.

We salvage 30/30 brass which is very popular from other shooters and hunters and fire form the empties. For plinking I use cast bullets and save a couple of boxes for serious big game hunting.
