According to Hodgdon data, the 44 Mag runs a 210 XTP a little faster at a little less pressure than the 41 Magnum, even with a shorter barrel. This holds true as bullet weights go up. 41 fans don't get butthurt over that.

What hobbles some (apparently) is that any stock 45 Ruger can be run right up with a 44 Mag for speed (because that's how interior ballistics work) as the same stock Ruger in 44, never mind the 41 Mag comparisons. No matter how you slice it, a 45 Colt at 1,300 with a 300 whatever bullet runs at less pressure driven the same from a 44.

Maybe you should contact Ross Seyfried and tell him he's full of [bleep]. It seems that's your beef here.

On deer sized game, there is very little difference between the two. On the really large animals, Ross Seyfried isn't the only one who perceives a difference between them.
The only real way to hash it out (for yourself or any audience you are trying to garner), is to actually poke enough stuff and advertise it to the degree Ross and Linebaugh did and convince everyone their full of [bleep]...
