I have a SH4 6-24 and with my old eyes have a hard time seeing the reticle below about 14X. I shoot NRL22 and normally have to run about 16X to see my holdovers. Is the SH4 4-16 reticle scaled differently? Would 16X on the 6-24 reticle equal maybe 10 or 12X on the 4-16 reticle? At 16X I have a reduced field of view which makes for harder target acquisition. Thanks Steve
