Doesn't surprise me at all. His idea that a few thousands of extra headspace, because the rim cut was too deep for the rim thickness of the shells being used, caused significant extra recoil is about as silly as anything I've ever read, here, or elsewhere. The only gun I've ever had that had excessive rim cut depth was a Crescent .410. The result was primer setback, not increased recoil. The shells stayed forward, as they gripped the chamber wall. This is what shells normally do! They didn't come slamming back against the standing breech, as Guffie implied in his ridiculous theory. He probably didn't even know there was a recoil formula, or what the factors involved were.
