I have a Sendero 300 RUM with custom barrel that I use for long range hunting and plan to use the 308 Win. only in the woods and in my tree stand where 100 to 150 yards would be a long shot. I realize it may not be the best powder but if it shoots around 1 moa it should be fine. I was just hestitant about trying something that wasn't called for in the reloading manual. When I can find it I will stock back up with the RE - 15 as it shoots the 168 amaxs between 1/2moa and 3/4 moa. Any other advice anyone could offer??
Well as the others have said a middle speed powder will give you better performance in your 308. However, I 4831 is listed in the hodgdon #26 data book with 150, 165, and 180 grain bullets.
The 165 with I 4831 starts at 45 and tops at 47 with a top speed of 2329 fps.. Just about a 30-30 or 300 savage ballistically. It would work to 200 yards if the accuracy was there. I'm sure that 47 is their top because of case capacity, since it is 38,400 cup in the test rifle(the 308 can go to 52,000 cup).
