Not to track off of your question too far, but since you're just starting, I recommend getting at least two manuals (not just the loading data you can print off the internet). Lyman, Speer, and Hornady are the 3 I use most. Plenty of info in them about processes in addition to loading data.
Second, be careful with that collet crimper in your hand press. I've got one for my 8mm Mauser dies, and after following the directions for it exactly, have succeeded only in crushing shoulders with my Lee hand press.
Third, that hand press will give you more than a forearm workout when doing bottlenecked rifle cases. Forearms, biceps, shoulders, pecks and back, maybe a little ab workout, too.
As for powders for both, I could consult a manual and tell you powders that are listed for both, but since I don't load .30-30 or .30-06, I can't help you with actual experience. Sounds like the guys here have given you good advice, though.
Good Morning Securitysix,
I agree with your comment about loading manuals. A loader on a budget can also get pretty good info for free when going to a gun shop by picking up catalogs published by powder and componenet manufacturers. These often contain loading data for their products, applicable to most common calibers.
As for the Lee collet crimper, I use it on every caliber I load for--including the bolt action ones, only I do most of my loading in a bench-mounted press. The Lee hand press, IMO belongs on every loading bench--you may not use it all the time but it can come in handy. I've had one for years--bought it when I had to live temporarily in an apartment. I used it to load pretty much everything, and you can full-length size with it if you have to. As you pointed out, as a side benefit it will help keep you in shape.
Have a Merry Christmas, and Happy New Year.
