How little? You've already proven how little you know. You're just reading numbers and not all of them. I've actually tested them on paper, in ballistic media and on critters. The Garrett 405gr is "Redhawk only" and 45,000psi, not a valid comparison. At the correct "Ruger only" level of 30,000psi or 32,000CUP, you'll only get a 400gr to about 1000fps. As I said, they offer no advantage over the 360's.
I never mentioned boutique ammo for two reasons, A) I don't use it, I handload and B) because it can only be compared to other boutique ammo. They use non-canister grade powders and run right up to maximum pressures. However, since you brought it up, Buffalo Bore's 340gr at 1475fps .44Mag load, which is safe in anything but a S&W, runs right alongside their 360gr .454 load.
The BB 260gr load runs 1450fps, not 1526. Same velocity as their 270gr .44 load.
All that data you've compiled but you've never read the Hodgdon manual? I don't make this stuff up.
None of this nonsense has anything to do with the OP.
