I had an opportunity to try the TTT at 50 yards today, with the same "combination of ingredients" as before, the BPS-SSX-WXRHD and basically the same weather conditions:
Wind: SE @ 6 mph
I had 43 hits (16 fewer than at 40 yards)
39 "through and through
4 pellets that did not exit the "wound channel" entirely
So, at 50 yards a slightly higher percentage of pellets, 91%, penetrated the TTT entirely than at 40 yards, 83%. I don't think the percentage differences are significant but it does show that the WXRHD pellets lose very little energy from 40 to 50 yards.
I continue to advocate shots of 40 yards or less however due to the very small target that a turkey head/neck presents at distances greater than that and the difficulty of holding a gun steady on such a small target at that distance.
I hope you find this of interest.
