If you are looking to "get your feet wet" with casting , the new double cavity Lee moulds are very nice. The C309-170-F is just the ticket for the 30-30. I like the 170 grain weight and gas check. For $20.00 and a little smoothing of any rough edges on the sprue plate, and this price includes handles, it's a great way to try casting.
This bullet shoots great in my 30-30 Winchester model 94 and a 03-A3 Springfield Rifle I own .
The new Lee double cavity moulds are much improved and I really like them.
