Started loading up some 30-30 Winchesters today, and found a few 303 Savage and acouple 32 Win. Specials casings in the lot. I looked up the loading specs. They're not the same! So I looked at some of my old yard sell type ammo, and found acouple 303's and 32 Win. in the boxes! Would anyone reload these casings for a 30-30 Winchester? Would anyone shoot these from their 30-30's?

NO! They shouldn't chamber in a 30-30.

Separate the brass, do not attempt to use any of them in your rifle.
Do you own any reloading manuals? If you don't, you really need to get yourself 1 or 2. The Speer/RCBS manuals have pretty good tutorials contained in them that deal with all the basics of reloading, including answering a question like you've asked. That your question is posted here at all makes me wonder if you have a good manual yet, and if you don't (coupled with a question like this one) makes me worry about what you might be doing with your reloading methods.
You might also find one of the online reloading sites has a lot of information that you should read thoroughly. Please be careful!

I presume you mean run a .32 Winchester Special case into a .30-30 sizing die to convert it. Frankly I've always wondered the same thing but I don't think I ever had any .32 Special brass to try it. But I have so much .30-30 brass that I don't know what to do with it all.
