ahhh BUT SOME .45/70 factory loads are way down close to really hot .44 mag loads LMFAO......
hell I will even admit that some factory rem coreloct .270win loads are down to .243 energy levels but on a whole the former will always out preform the later in energy if you comparing apples with apples.
one of the biggest issues with comparisons like this is that the origonal is being asked to preform outside its brief......if you want .30/30 preformance buy a plurry 30/30
its like buying a .308 and then trying to hot rod it to poke 150grn pills out at 3000fps and expecting it to handle the pressure......go and buy a 300 mag of some sort...you can do it with ease WITHOUT pressure threatening to either blow up gun or or silly fool head off.......... I very nearly fell out with a great Mate over that very thing a couple of years back.
