It was spectacular to see what it did to milk bottles full of water. Now it isn't everyone's cup of tea, so each to their own. There are people that will ditch a rifle in favour of a "better" calibre, so why not stretch the operational envelope of your existing firearm?

Yeah it's a pretty well standardized with many pistol cartridges e.g. 45ACP has a limit of 21,000PSI and 45ACP +P is has limit of 23,000PSI.

There is 257 Roberts (54,000PSI) and 257 Roberts +P (58,000PSI). And people obviously wring the piss out of 6.5x55 in Tikkas these days (although that's not one that's standardized as far as I know). Besides that, "+P'ing" is not really a thing with rifle rounds as they already have much higher pressures than even the spiciest NATO spec 9mm or full house 357's already.

There's nothing saying you cannot stretch the envelope with a 45/70 besides your tolerance to recoil and the strength of the gun. But it already has three tiers to indicate how spicy the rounds are to cater for this. So saying "+P" in the context of 45/70 is a bit redundant and confusing as to what it actually means. +P trapdoor 45/70? Is that like a standard or even a -P lever gun load?? Why not just say "lever gun only"?
