I'll be reloading hornday 60g SP FB for the .223 for fox and roe, but also want a more out-and-out fox round and target round (fun target in the field, not on range stuff), so I was thinking the V-max in a similar weight, both with N140. Does anyone know or are able to calculate with some fancy tool if the ballistics will be so close in structure that I could just interchange them without having to worry about re-zeroing?
