Does the 450 marlin have a real advantage over the 4570 ? I was thinking about buying a guide gun in one of these calibers, but I had read somewhere that the 450 is a better round. This would be for whitetail hunting , maybe moose. thanks a lot
You should combine your two posts. Factory loads for the 45-70 are now available from PMC,Buffalobore and Garrett that will easily take moose or just about anything. Standard factory loads are graet for deer.
45/70 is far more versatile. The best all around load is a 350 grain jacketed bullet at about 1900 fps, like those made by The Hunting Shack , but you have a choice of so many
For all intents and purposes they give equal performance. The .450 marlin has no advantage ove the 45-70 if you use the semi custom ammo from firms such as buffalo bore, garrett, cor bon, or good handloads.
My standard load for my Guide Gun is the 350-grain Hornady RN or FP at 1700 fps. For a .450 Marlin equivalent, I shoot a reduced load in my .458 WM with the same bullet at 1250 fps. The bolt action stock is much more comfortable at that power level than a lever action stock.
