I tried a couple pounds of Ramshot Tac when Varget was impossable to get. Despite decient accuracy out of a stock 700P, the heat of explotion is very high with this powder. I found that my barrel was heating up way to quick "ie" 4 or 5 rounds was the max eave when waiting 45 to 60 seconds between shots. I'm sure in my case if continued I would have incured major throat degredation.
 
varget or imr4064 for me.43-44g of 4064 and 44-45g of varget.both with a 168smk/175gsmk.but I am useing a 5r rem.and that is what mine likes.JOHN
 
I have used Tac in my .308 win and .222 It worked great and meters nicely. It is slightly faster than varget. I seemed to get the same velocity out of 43 gr tac as 45 gr varget. Black hills uses it in there .308 rounds so it must work pretty good.
