OOOPS, you're right I did forget to mention the cartridge. I need the info for the .308 winchester. Stub, I understand what you mean about what powders may shoot well or may not shoot well out of this rifle until I try different ones but if there are powders that generally shoot better than others with the 165gr bullets then I'll have a good starting point.
Thanks.

If you're not huntin' you're not livin'!!!!!!!!
