Look at all the reloading manuals, and you will see that you have a choice from 180gs to about 550grs so if you reload , you can go from short range plinkers to large game cartridge. For one of my single shots, used to use BP some filler and a 459dia rd ball and use channel lock pliers to seat it, fun round. There is so much info on the 45/70 out there you wont have time to shoot.
