As I lay in bed last night dreaming of Twin Lakes, Alaska, I got to thinking of rifles, eventually thinking about the .45-70. After all, that is bear country. In the late 1800's, after it was introduced in 1873, the .45-70 may have been considered the standard big and dangerous game rifle in this country. There were other similiar rounds, mostly other .45 caliber rifles and the .50-70 was still popular and all these were in the same class. The .38-55 and .44-40 were not in that class. Now these might be considered marginal in the original load, at least for very large game like moose and brown bear. The first competition probably came from the .30-06, though many rifles in .30 Government were happily used by people who appreciated the lack of smoke, even before the '06 came along.
Then I got to thinking about the rifles they were using during this period. Mostly they were a little heavier and had rifle length barrels, around 33-inches in the Springfield. Winchester and Marlin lever actions were not that long but generally (I guess) longer than the barrel lengths more popular these days. There were Springfield carbines but a special cartridge was used for them, same with the .50-70, I believe. Hard to find much information about the .50-70 but obviously the .45-70 is still going strong.
Eventually I began wondering if it was possible that the black powder, .45-70 round, with either the 405 or the 500 grain bullet, when fired from a longer barreled rifle could have been more powerful than a current production, standard pressure .45-70 round, this time with either the 300-grain or the old 405-grain bullet, fired from a shorter barrel rifle. In this sense I suppose I can only refer to foot-pounds of energy over a 300-yard range or something like that as opposed to a less objective "killing power" factor, no matter how you measure it. In the same way, I wonder if the original .45 Colt load as used in a 7 1/2 SAA was more powerful than a current load fired from a 4" S&W Model 25. In any case, I am excluding the hot-rodded "Ruger-only" loads.
I know it is only an academic exercise and in a way, front loading the results by comparing long barrels to short barrels but that is the main point in the first place. The real question is, have we come that far in 130 years?
