I was looking at the frontier firearms site at the Savages they have for sale. Specifically the "Savage 10 FCP HS Precision Stock 308" and the "Savage 10FCP McMillan". Does anyone know why the McMillan is almost $500 more than the HS precision? I'm guessing it is a different stock, but other than that I'm not sure. Does this stock make it shoot considerably better? As well, I was looking to use this rifle out to about 800-1000 yards. Is this rifle accurate straight out of the box? I will be handloading Berger 175gr VLD's in it. I'm not new to shooting, just new to precision shooting. Sorry for all the questions and thanks in advance!
