Gentlemen, there is one thing you need to know about the old 45-70 Gov cartridge and the rifles that are chambered for that cartridge.
The reason the 45-70 Gov is named the way it is, is because it was made for the 1878 Springfield trapdoor military rifle, and carbine to be used for killing humans. It was also used to collect meat supply for the troops while on patrol, in Indian country. I even have a “wood incased” bird shot 45-70 cartridge that was issued to troops to shoot birds and rabbits with the trapdoor 45-70 rifle. Sort of the original shot shells made for pistols today by CCI. The rifles and cartridges were well designed for their intended purposes they were designed for their time in history.
I own three rifles chambered for the old 45-70, and have owned many more over the last 50 yrs or so. I today’s firearms, the cartridge will do some thing much better than it did in the old days, because of stronger guns, and hand-loading for those newer guns for special purposes.
The cartridge has always had it’s handicaps, and most of those are still in effect today regardless of the better rifles, and loads that can be used in those newer guns.
The problem with the guys who shout so much BS about how powerful the 45-70 is, are either trying to sell you something, or in most cases have no idea what they are talking about, and/or believe the guy who wants to sell them something! Most of those guys have never shot anything bigger than a goaty old whitetail deer, or shot a bigger rifle than the 45-70, and are in a word full of crap and most are not over high school age and have a lot to learn about African elephant if they think this cartridge is an ELEPHANT CARTRIDGE. The 45-70 is not the best stopping rifle for the lower 48 in the USA much less in Africa. Even with a lower 48 Griz, I would far rather have a 338 Win Mag, or 375 H&H and neither of those can be counted on to stop a griz every time, but they are certainly better than a 45-70. Also the 375 H&H is legal in Africa and the 45-70 is not.
The 45-70 with a VERY strong rifle, and HOT hand-loads, is workable for all North American animals under the right conditions. Especially if that is all that is in your hands when they are encountered. In a short repeating rifle it is a better self-defense weapon than a pistol, but a dependable STOPPING RIFE/CHAMBERING it is NOT!
AFRICA?????? Well, of the big five it would be OK for the two cats over bait, with the afore mentioned HOT hand-loads, with proper bullets, and the very strong rifle. Cape buffalo have been killed with the old 45-70 but that doesn’t make it a Cape buffalo rifle/cartridge combination, and in fact is illegal for that purpose in every country where those animals are hunted. That is not to say that PH sometimes alow it to be used for that purpose, they do on occasion! However anyone who allows that cartridge to be used on an elephant is a little light in the brainpan, IMO!
It does no good to argue with the 45-70 crowd because their minds are fixed, firmly in their head in the sand along with the ostrich. Ignorance is not an indication of one’s intelligence! It simply means a person simply doesn’t know something. The stubourn resistance to information that corrects that lack of knowledge is another matter all together!
