Back to the bases and rings comments, does a one piece, such as EGW, allow enough room to easily top feed the cartridges? I was thinking a two piece would make it much easier. Also, as to the Warne or Burris Signature Zee rings, will a medium be too high with a weaver style base in either Warne or Burris? Warne has low and medium, but Burris Sig Zee only comes in medium. A 40mm optic in a one inch tube will be used. I don't want to order mediums if the lows will work better.
