To get the most out of your 45-70, I would learn to reload if you do not already. Even if you can afford to buy all the ammo you want, you will be amazed at how much fun reloading is with this round. Since I've had my 3 45-70's, (Ruger #1, Marlin 1895 and H&R buffalo Classic), I have developed over 30 loads. I cast about 11 different bullets for it and mess with a dozen powders at least. Everything from 405gr. 900fps to 500gr. 1800fps. for the Ruger to 300gr. 2400fps. You can play with cast or jacketed, 300gr HP., collar buttons, round balls plain based or gas checked cast. The sky is the limit and you will find that even after years of playing with the gun, there is someone that has used it differently than you. Its hard to overload it for deer, as it tends to not destroy tissue the way a high velocity weapon will. Have fun, and watch out with your new toy!
