Actually is does kick more because of total ejecta weight. The powder is part of the total weight. Look up a recoil calculator, they include the weight of the powder too.

Ive never changed just the powder weights to compare them but it is part of the equation. The guy on Dougs that shot it also used the 325gr FTX at 2300fps+ sabotless in a 45cal. That is gunna kick like a mule no matter what. My load uses it in a sabot with about 65gr of smokeless and the psi is about the same at 2250fps. Recoil is very noticeable.
