Recently I purchased my 700 .308 SPS Varmint. I have the Redfield Battlezone scope arriving this week sometime and while I was at Gander Mtn I asked about the tactical base. He recommended the weaver 2 piece rather than the 1 piece for the base. I asked why and he said about some of the rounds may hit the base and travel back to cause a misfeed for the next round. I've seen pics of both and more have the single piece and to be honest it looks more radical but function means everything to me. Can I get some opinions and stories of your experience in this?
