I've got tons of brass for the 32-40 and the 30-30. Not sure how much I have for the 25-35 but I always keep my brass so I must have a decent supply in my store room. I wouldn't think cost would be too bad. I'd need dies of course and the correct dies for my trimmer. Most of the rest is just normal reloading stuff (powder, bullets, primers etc) I would think.
