I use the 311041 and a mixture of wheel weight metal, lead & 50X50 solder from a receipe in the Lyman catalog that equals #2 alloy with very satisfying results in an 03-A3--for when you get to the 30-06. I also use it in the 308 and should be great for the 30-30.
The 311041 is a flat nose that gives a relatively clean hole in paper, and a really good smack when you shoot a varmint with it.
I use a Lyman step die stem to open the case a little 'cause the bullets are sized to .311. Lyman molds typically are a little oversize for the bore, and I size to .311. I tried to size to 308 like a jacketed bullet when I started out, and destroyed the bullets trying it. Cut lead off the bullet trying to get the 311 bullet into the regularly sized neck. These are the little things you need to consider when casting for a 30 cal.
26 gr 4198 is my current load, although I've used 30 grains of 3031 for one load, and 4064 powder for another--I don't have my load book with me.
The 311041 shoots very accurately in my 03A3--as well as jacked bullets or better, and I've taken this 03 along when I'm hunting woodchucks. Good accuracy, hits out to 200 yds, although I now restrict shots to 100 because I don't get the good wollop needed for a clean kill much past 100.
I think you'll enjoy casting bullets for your 30 cal.
