I once had a .375 SM in a stainless Seville! Nice gun. I didn't do too much load development for it however, as a local gentleman once owned the gun, and finding out I had it made me an offer I couldn't refuse.
What I did find during that brief time however was that it preferred AA 1680 over all other powders. In accuracy, pressure and velocity, it couldn't be beat! Unfortunately, and (stupidly I might add), I let all my loading data pages from my notebook go with the gun! sorry no data to share here from a first hand account!
The brass I used was cut-down .38-55 and I used both jacketed Hornady bullets as well as an assorment of cast bullet weights. I think the best cast bullet weight for that gun would be a 210g in a WFNGC bullet! It would be a screamer, and have the wide meplat for nice big wound channels.

I have no experience with this revolver/cartridge combination. Ah, but I know who does. Check with Mr. John Taffin over at his <a href=http://disc.server.com/Indices/47763.html>Campfire Site</a>. I know he's tested the gun like only he does.

B WOOD, get on the phone and call E.Arthur Brown Co. at 1-800-950-9088 and order a copy of 'Shooting Steel'. There's a whole section on the Seville 375 SM,pluse lots of load data Some loads listed are: Hornady220gr.jacketed H-110,23.5gr=1623fps IMR4227,23gr=1618fps H-4227, 21gr=1305fps The last load was chrony from a DW,it will do 1600+ out of your Seville! Like Marshall said, AA-1680 is great in the 375 SM. Its the best for full power loads in my 445, but H-4227 is more accurate. I didn't see any 375 loads with AA-1680, but it shouldn't be to hard to figure out a startingload. Best bet would be to call Sierra if your unsure. I hope this helps. Royce
