LAST EDITED ON Nov-03-12 AT 11:47PM (MST)[p]Ya know, funny that you guys should mention the 6mm. I already mentioned my early but consistent findings with the .243 but in fairness, the results that i spoke of were back in 1964- thru about 1974 or so with dad still getting his two bucks a year without fail. At the time, i think he was using Winchester 100 gr ammo but he didn't pay much attention to that and it always cracked him up to see the panic on my face as the mortally hit deer ran off. I'm color blind, bad, and have a hard time trailing blood. Few, if any, ever got away but like i said, i'd moved up a notch to the 25-06 and it flat stamped them where they stood.
So some years later, a friend offered me a killer deal too tough to pass on his Leupold scoped Browning B-78 single shot. 28" octagon barrel and a exceptionally fine rifle both in shooting and to look at. It was though in 6mm! There is not a whole heck of a lot of difference between the .243 and the 6mm, about a 100 feet per second maybe and my longer barrel could/should have added a bit more to that. But in the 5-6 years that i carried it, that 6mm seemed to put them Blacktails down better/faster than Dad's, now my, model 70 .243 did back when i was younger.
I don't know, again, maybe it was the ammo or bullet selection. That in itself can make a big difference in how a deer reacts when it's hit in a good spot.
