Not sure what you are going to use it for or your limit for cost. Remington makes a 405 grain factory load that shoots very well and the cost is about $35 a box. Cor-Bon makes a 460 grain hard cast load. Buffalo Bore makes a 430 grain hard cast load. Garrett also makes some heavy loads up to 540 grains. Unless you are going after dangerous game I think I would give the Remington 405's a try as the cost will be much easier on you then the other three. You may find that your 45-70 shoots 300 or 350's just as well as heavy bullets. What model of 45-70 and what game if any are you aiming at?
Im getting the 1895 GBL.
Ill be stalking and also shooting hogs from a stand. Probably nothing over 150 yards.
I wanna hit'em real hard and make a big mess,,,ya know.
I just want something big, heavy and accurate.
The 405 sounds good for the price. Where can I find some ballistics on the 45-70?
