I have a question for those smarter than me. I have always used Weaver type bases and rings. I have never had any problem with this set up. But I am wanting to try something new. I am looking at the Leupold rings and bases. What are the pros and cons of the standard set up versus the dual dovetail set up? Is one better than the other? Are they about the same? How about one piece versus two piece? Can someone please educate a brother. Oh yeah these will be going on a 243. Thanks
