IMO, Bird hit the proverbial "Nail on the head". Buying significant quantities of the same Lot #'s of any given ammunition which delivers outstanding performance in any type of firearm is the prudent thing to do. However, I think a lot of "old" turkey hunters like myself have done just that, only to see a "newer and better" turkey load come out with performance which eclipses the "old-best load". I'm sitting on 10-12 boxes of the Activ 3", 21/4 oz Nickle loads, which in their day, were the best turkey loads I'd ever patterned and which accounted for a number of dead turkeys. I then loaded up significantly on the Remington 3' and 31/2" Hevi-shot shells which amazed me. I've shot most of my "old whites" and moved to the EM Hevi-13 gold hull with phenomenal patterning and killing results. I didn't "rat hole" a lot of the Hevi-13, 7's, since I figured they wouldn't tinker w/ such a proven performer and I felt that it was only a matter of time before some company jumped on the TSS bandwagon w/ a factory offering. Well, I know that I've got a huge inventory of "turkey killing" shells, but I'm just as anal as most of the folks on this site and have become entranced w/ the unbelievable performance of the new generation of factory turkey loads.
