I'll definitely recheck the Thomas reference, which I think I'm remembering correctly--because I've cited it here before, and I've received the same replies. And I think I've made the same comments, which I'll repeat once again:

If a powder company is selling a variety of powders--which they all do--what "axe" are they grinding by promoting one as recoiling less than another? Like, Alliant is going to make more money getting folks to switch from GD to RD--or vice versa? Sorry, but that one does not pass the logic test.

In addition, there are some folks here who are nonbelievers in the existence of such a thing as "felt recoil", as distinguished from "measurable recoil"--even if a bunch of experienced shooters say "Hey, that load kicks more than this load", when doing the math would indicate that there should not be any difference. Felt recoil is a bit like the existence of God: it's something you have to accept on faith and the personal testimony of "believers", because it can't be proved scientifically.

As for defending Gough Thomas, I don't intend to go there. However, I will point out that he pretty much invented the MOI concept of gun handling dynamics, in which a lot of folks place great store. Jim and Miller, while I respect you both for your contributions here, can you claim any such ORIGINAL concepts you've come up with???
