RE: Want to start reloading
Bigbore - With the cartridges your going to be reloading for, except the 22-250 and possibly the 30-30 you won't need one, but a case trimmer should be on your purchase list in the future. (It would make a nice Christmas present).
A set of dial calipers come in handy too for measuring case length and OAL.
Also, when you start, remember, that your 45-70, 44, 450, 45 - all the cartridges being shot from a revolver or tube magazine rifle need to be crimped. Follow the instructions with the dies for this.
While we are on the subject of dies. For these straight walled cases, but the carbide dies. They are a little more expensive but eliminate the need for case lube. For the 30-30 and 22-250, you need to lube the cases. Hornady "One Shot" is a great lube. It is a spray on lube that will not contaminate powder or primers.
Good luck on your reloading adventure and post your questions in the reloading forum. There are plenty of guys here ready to help.
