300 WSM Powder

Looks like I'll be loading for a 300 WSM soon. I will be using 180g Nosler Bullets. Curious to see what peoples favorite powders are. I have the books just wanting to get some direction. Thanks.
Comments
I would expect that the faster burning of the "usual suspects" for the Winchester 'Long' Magnum will work about the best for our WSM's. FWIW: It took 72 gr. of IMR4350 to reach 2950 with 180's in my 24" Winchester 'Long' Magnum.
Good luck with your rifle.
R-17 and MRP are tough to beat as well.

Once I found the load the rifle likes, I would buy bullets and powder in stoichiometric quantities.
I use H1000, which I didn't see on steve4102's list. I also didn't see VV N170. Both good powders.
Thanks for posting those![:D]
