I don't agree with this.

I think the Marlin is perfect for the .45-70 for loads in the mid-range of the cartridges potential. True, at 1800 fps + 400 grain bullet, the gun is a grim proposition, but I shoot a 402 grain cast Hollow Point at 1640 fps and that load is a sure killer on all critters I've shot with it.

As far as a double is concerned, for practicality, I agree with Bramble, a 9.3x74R is more practical.

But it isn't a .45-70. If you want one, get one. A double .45-70 even at factory velocities of 1200 for the 405 is a killer and at the standard 1800 fs with 300 grain bullet it is devastating on deer. It'll kill anything on this continent.

Want a .45-70? Then get one.

But please don't tell us you are planning to run a .450 Rigby chambering reamer in the gun and you are wondering about loads for 600 grain bullets...
