Just looking in the manuals as I don't load the cartridge, IMR 4350, H4350, RE-19, Viht N560, and IMR 4831 are all listed. For the 250 gr GK bullets, (OAL 3.340") Sierra lists an accuracy load of 68.8gr RE-19 and a hunting load of 72.0gr Viht N560(MAX LOAD). Hope that helps.
corvette8n I use IMR 4350. Don't recall loading any at 275 Grain but 225 and 250.
Ken.
Re loader 19 and 22. Did 2563fps with Re 22 and the old Speer 275(1/2" @ 50yds)grain load was in the low 70's.Re 19 did 2541fps at near max. a little larger group.
http://www.chuckhawks.com/rifle_cart...ading_data.htm for 200/225/250 grainers.
Cartridges Of The World give 68 gr of IMR4831 for a 275 SP at 2500fps (Speer source).
To complete these data, IMR's free Handloader's Guide lists 68.5 grs of 4831 (compressed charge) with a 300 gr Power Pt.

I've had good luck using 200, 250, and 275s with RE-19. Play with to taste.
I've used H-4831 in my two Ruger .338 magnums using 250 to 275 gr. bullets. I used 71 grains as a good starting point with the 250 gr., 68 grains with the 275 grain and magnum primers in either case. These are compressed loads.
