.338 Win Mag question

[corvette8n]

I have a box of each: 275gr Speer, 250gr Sierra, 250gr. CT partition gold moly
is there one powder I can use for all three bullets, I have a Savage 110 in .338 win mag.

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.

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.
