My 45:70 Marlin. MANY years ago I managed to break the stock on this wonderful rifle and have been unable to acquire a new one (even though it has been on my ‘present list’ for close on 20 years). To my surprise my wonderful family managed to source one for my birthday yesterday. I’m not sure whether I am now too old for this rifle. It IS a blunderbuss (and quite heavy), but we shall see. At least Matt and/or Bryn may enjoy the use of it. Originally this was the round which wiped out the American bison. It was then (as now) .45 calibre (ie 45/100ths of an inch) and was loaded with 70 grains of black powder. NOW you can load (a modern version of the rifle) up with over 80 grains of modern chemical propellent and 500 grains (that’s half an ounce) of copper-jacketed lead. It comes out of the barrel at over 3,000 feet per second and is still going nearly as fast as a ‘baby’ .308 @ 100 yards, but with immensely more kinetic energy. When the projectile mushrooms out, you would have to see the damage to believe it: it is awesome. Small game (wallaby size) just disintegrates! Something the size of a man will have a hole you can push your whole arm through. Anything hit in the chest will be very suddenly, very dead. It is an excellent big game (eg sambar deer) rifle. During the war against the Huk in the Phillipines c1905 American marines brought it back into service as they found (surprisingly) the full metal jacket 30:06 just didn’t have the stopping power for these crazed folks who were completely hyped up on some bizarre concoction of drugs, their gonads tightly wrapped with wet greenhide so they wouldn’t feel any other pain & etc. Allegedly you could shoot them through the heart with a 30:06 solid round and they would still run a 100 yards and chop off your head with a scimitar (you can probably guess at their religion!) The old 45:70 knocked them over backwards and they just didn’t have the ‘heart’ (literally – or much else) to get up again and keep going. I can’t imagine that the current puny .223 round would stop such folks! Perhaps I will stock up on 45:70 ammo!
