I'm thinking about buying a used (like new) H&R 45-70. It has had only 35 rounds fired through it, walnut stock, interchangeable sights, and the guy is wanting $300. In looking through my data books it appears that the heavier the bullet the better. There's a big difference in pressure between certain powders also. I'm leaning towards the 350 grain bullet and IMR4198 powder. That combination gives a faster bullet with much less pressure. What do you like to load?
