I am going to start my accuracy quest with the 150gr. Sierra Matchking for my 7mm-08. 22" barrel, 1:9.5" twist.

Looks like the usual suspects are oft reccomended for 7mm-08 but I can't find anything on the net specifically reccomending powder to use behind the 150gr.SMK.

Here's what I'm thinking in order of which looks the best so far:

Reloader 17 - too slow?
IMR4350 - too slow?
IMR4064
Varget

Someone mentioned to me that with the 22" barrel that the quicker powders may be more efficient. I found the most accurate loads in my 22" .243Win with H4350 even though it may not be burning up all the powder. What do you guys think?
