Home Forums Birds & Dogs Turkey Hunting TSS facts verses fiction

They don't, at the same velocity. There's plenty of online calculators out there that show this is correct. For instance at 1100 fps, a #9 will have 4.5 joules of energy, a #7 TSS will have 7.31 joules of energy, and a #4 lead will have 9.4 joules. All at 1100 fps. But there's more TSS shot for given weight, and TSS, according to published data, indicates it retains its velocity and energy better than lead.

So, at the muzzle, pellet to pellet, LFC is right. 30, 40, 50 yards out, they aren't traveling at the same velocity anymore.
