I am familiar with the more traditional powders used for the 375 Win. So lets leave R-7, 4198, H322 out of this. I wouldn't mind hearing a bit about 1680, though. I am specifically interested in trying TAC or R-17 in the 375 Win. I can't find any load data, however. I am quite certain TAC should do fine, and I have a lot of it on hand. The R-17 is based on what I heard one guy say at the range, and what I heard one guy type on the internet. Obviously, both used it and claimed it worked well. I don't have any on hand, but some is 5 minutes away if needed. The Western manual, nor the Hodgdon or Alliant manuals list ANY 375 Win loads at all. Any help from anyone would be great. Thanks......

Hornady's latest manual lists 41.2 grains of 1680 as max with their 220-grain bullet. It's the fastest load listed, at 2300 fps from the 20" barrel of a Winchester 94.
When there's no TAC data for a cartridge I use IMR4895 data as a starting point.
I can't imagine RL-17 working worth a darn in the .375 Winchester, so suspect both guys meant RL-7 and either misspoke or typoed.

I found the R-17 comments rather odd, myself. But after hearing it twice, it made me wonder.
I will have to check into the 4895 data for the cartridge. I don't recall seeing any, but there may be some. I have read of a couple loads on the net, and have a bit on hand.
I called Don from Western. He is actually contacting the lab, and calling me back about the TAC data. Which is very nice of him. I can't see why TAC wouldn't work at least fairly well.
I was thinking 2420 data may also work as a starting point. But of course, no data on that either.
Thanks....

The last Handloader has some 375 loads by Brian Pearce.1680 was one of the mentioned powders.I bet LVR would work.I mostly use R-7.

Sadly, I have everything here now but the powder I actually want. 1680 or R-7.
But I could give TAC or H322 a go....

i did find a source recently for 220grain jacketed soft flat point bullets for the .375 winchester. A guy in california makes them. You will see a reference on the marlin owners forum. Nice looking bullets. I intended to scrounge around town this week for that 1680 powder reading the same article.
i might add I think they are going to start producing 200grainers at the end of the month.

.375 is a mighty fine round. I was sighting in a little scope i put on the marlin, and fired four rounds, thought i had a problem in that i only saw two holes. Went up to the target and realized two bullets went in the same hole, thus four rounds, two holes. I was impressed. And that was with a cast bullet too.

I just happened to see the thread title in the forums list. I agree that RL-17 has absolutely no use in the .375 Win and has to be a typo. In my Contender barrel, RL-7 was THE powder. I confess I never tried 1680 or LilGun in it, both of which are rumored to be even better. That barrel is long gone, so I'll never know.

I talked to you long ago, on another board, about the 375 IIRC.
I remember you liking R-7. Was just wondering if you ever tried anything else.
I have fresh data from Western, using TAC and 250 gr. bullets, if anyone is interested.....

I am a 375/38-55 fan of many years. I have tried the "common" powders and agree that Re-7 is an excellent powder in these rounds. AA 1680 has given me highest V with heavier jacketed and cast bullets. 38 to 39 gr of AA 1680 with 220 gr jacketed has given me 2400fps from a 24" barrel. ** max load - start at around 35gr with 220's and 36 with 200's. I have gotten excellent accuracy with 1680 and 5744 (especially with cast). Accurate powders were common and easy to find here in Tennessee - now, GOOD LUCK . I do not know if they are still in business, but a company named "Northern Precision" made many interesting jacketed large bore bullets years ago. I have some 270gr "Powerball" (think a large hollow point with a 30 cal plastic ball in it) bullets that really expand at 375 speeds on whitetail!

I tried AA1680 about ten years ago and even though it gave some smoking velocities, I felt I needed to work with the loads some more as the accuracy wasn't quite what I wanted. I seem to remember stopping about 38 grains with the Hornady 220. I have been so satisfied with the other powders mentioned that haven't gotten into the two pounds of it that I have left.
Unfortunately about the time felt like working with it again, the Hornady 220's became scarce, and the few hundred I have left are gonna be rationed.
If they ever crank up production again I might work on the loads again, but it'll be my luck I won't be able to find any more 1680.

Lyman has loads for AA 2230 listed and from what I've seen in the parent load book Exterminator is the same as 2230.
After the first shot the rest are just noise.
