I recently picked up a 99 (not sure the sub model) in .300 Savage made in 1956. It is factory drilled & tapped for scope bases and I'm wondering about which way to go. I've seen the one piece bases and rings by Leupold and the various two piece weaver mounts. Seems like the one piece would be a lot more accurate and be more appropriate to the 99. The two piece are obviously cheaper and easier to set up. What say the experts?
