Looking for a hunting loadin .308 Win for a Springfield Armory M1A Scout/Squad rifle. I want to use either a Nosler Siver Balistic tip with a 150 or 168 grain bullet. I am very partial to Vihtavori powder, specifically N-550 and N-540. Any ideas? I understand the gas system of this rifle can be sensitive to certian types of powder. Also a load in .44mag for a 265 gr beartooth WFNGC (for black tail deer) and 325 gr WFNGC (really big angry things). Again I have great luck with Vihtavori powders like N110. This will be fired through a Freedom Arms revolver. Any suggestions would be greatly appreciated.
