Im looking to order up the sizer die for the 170 grain 30 cal bullets for use in a 30-30.  Should I be looking at the 308 cal die or the 309 cal die?  Or none of the above and I should get (enter your answer here)

.309 minimum maybe .311

A cast bullet too small will cause leading and poor accuracy.

It is almost never bad to have a slightly oversize cast bullet.  If it will chamber it should shoot well.

Thanks for the info and good to know.  I have worked with some sizers before, but they were already purchased.  My buddies dad had already figured this stuff out.

The proper technique should be to slug your barrel, then choose a sizer that matches or slightly exceeds the slug size.
That being said, I haven't yet slugged mine, and I size to .309, and they work good. Mine are also gas checked.

I had ordered the .309 sizer.  I already have the sizer/luber press.  I should get the parts early next week, I have a camp/shooting trip later next week so I will run a batch or two through when I return after Easter.  I will report back. 

Do you use a specific alloy for the rounds with the tubular mag?

I've only been casting a little over a year, and haven't gotten that much in to alloys. I pretty much use straight wheel weights, with a little tin thrown in for easier fill out. Lyman #2 alloy is 9# wheel weights to 1# 50/50 solder. Here is a site with a ton of info on alloys. It also has some great reading on heat treating/quenching cast bullets.

Here's a secret for getting tin. Check out Goodwill or other 2nd hand stores for little pewter items. Only get the really cheap stuff like cups and such that you can get for around a buck a piece. It has to say pewter on the bottom to be real. Pewter is over 90% tin. Melt it down and cast it into ingots just like you do your lead. Add a little bit to each casting batch. I add maybe a few ounces per casting pot.
