I use either Saeco 20 lb furnace, or a large propane burner used for deep frying fish, turkeys etc with an old dutch oven that will hold about 60 lbs of metal. Either one works just fine. I dip, using one of the cheap lyman ladles with a hole in the bottom that fits the mold sprue. My 30 cal mold is a lyman .31141 and I'm happy with it. Saeco sizer, I size at .311; .309 destroys my bullet, it casts big so I went to .311. Alox 50X50 with beeswax lubricant. No leading, works and is accurate. Hornady gas checks, that crimp on the bullet. I've used different powders, including IMR4198. I use a #2 alloy mix, from a receipe I found in the Lyman loading manual that uses soft lead, wheel weights and 50X50 bar solder. I've found that with my alloy I need to get cracking and size the bullets within a couple of days, otherwise they get so hard I can't push them into my sizing die! They become realy hard. Check out a Lyman M die, that opens up the neck of your '06 case a bit. It's easy to load cast that way. Segregate your '06 cases that you use for cast bullets from others. The strike of the firing pin will affect the headspace, I'm told. I paint the base of my cases with my wife's red finger polish (don't tell her for crying out loud!) so I know those cases. 100 cases seem to last forever.
Hunting--my viewpoint only. I've hunted woodchucks with my '06 quite a bit, and the .31141 really smacks them out to @125 yards or so. After that, I find I start to get crawl-off's. That has been a pretty consistent experience, enough that I don't think I'd hunt deer with that combination without going with a softer bullet, hollow pointing, or something. I find that my load shoots lower than the full-power '06 load. I use a Burris scope, and I find the range graduations can be used for the cast load. Just experiment a bit. Good luck! Let us know how it works for you?
