I have had good luck with Reloder 22 and 25 in 7mm magnums, both Rem mag and Wby mag. Similar case capacity. I have had mixed results with CCI benchrest primers on other loads.

I would suggest utilizing data from the Nosler reloading guide as Nosler has based thier load on their brass and bullets.

IMR 4350 is useful in such loads as are RE 19, 22 and 25. as Del mentioned H 1000 is also a good one.

I have included links to the Nosler, Alliant and Hodgdon sites below:

I have tried most suitable powders over many years and have found reloader 22 the best for my purposes especially with heavy bullets(200 grains)

An afterthought, Follow the manual as to how many grains. What may be an over load in my 300's may not be in yours. Work up carefully, the powder is fine, I use it in three 300's, they all like Reloader 22.

Happy Miles,

Do you find Reloder 22 to be a stable powder in extreme temperatures? Just wondering what with all the marketing hype from Hodgdon "Extreme" powders and all.

Best regards,

WA Mtnhunter,
I have used it with hot loads below zero elk hunting, below freezing at 17000 feet in Central Asia, 102 in Namibia where humidity was low, and in western African jungle were hot (high 90's) and humidity was high. No extraction problems, strange ignition issues or other weird happenings. In fact everything always seem to drop dead. Never been able to use it for an excuse for anything.

reloader 22 and h4831sc are pretty much the tried and true powders for the 300 winny. much like 4064 and varget are for the 308 winchester. i've heard that reloader 22 can be temperature sensitive but when i talked with a fellow at alliant powder he assured me that the problem was remmedied years ago. i've had good luck with it.
i'm gonna try h4831 in my custom rig and see how she does.
good luck with it buddy!
