I'm one of those contrarians MD mentioned. Once I decided that 200 yards was the farthest I would walk to pick up an animal, my life got a lot simpler. It does not take a super zippy load to reliably work at that range.
Friend, does that indicate age ? or the decision to not spend that much effort ?
As for myself, I must walk whatever that distance is to verify shot placement and expected
demise of game. After that I walk to my 4 Wheeler for retrieval.
Thanks Mr D
