How much will it mess me up to buy a FFP scope when I have only used and own SFP (5+ years). I really like the Leupold Mark 5 but it’s only offered in FFP. Truth be told I don’t really use the reticle for shot correction. If I’m half a target width to the right on my first shot then I shoot half a target width to the left for my second shot. I’m more of a hunter than a benchrest or match shooter. Can I use both types interchangeably?
