Getting into casting is kind of like making your own beer. Once you start doing it, you can't quit. I shoot cast bullets in a lot of my guns. Most of my handgun shooting is done with cast bullets. 32-20, .44 Mag/Spl, .357 Mag/Spl, 9mm, .40 S&W, 10mm, .45 ACP. More economical and excellent accuracy. Use the same bullets in my handgun caliber rifles. .30 Carbine, .308W, 30-30W, 30-06, .338WM, 40-65, .45-70. Gas checks on the 30's and .338. Cold lubes are easier to work with, but heated lubes are less messy to load. Haven't used liquid lube except on my 45-70. Jury still out on them. I use WSF powder in my auto pistols and 296 in my magnums, recommended powders for .30 Carbine and 32-20. SR 4759 was my powder for my rifles until it was discontinued. I used 5744 until I discovered Shooters World Buffalo powder. Identical loads to 5744, meters better and much cheaper. I have used the same Lyman bottom pour pot since 1975. I have Two of each, Lyman and Magma Engr. lubersizers. The Lyman works better with gas checks. I have two so I have dedicated cold and heated lube presses. Commercial lubes work fine and you can find many recipes especially on the Cast Boollets web site. I've had best results sizing bullets .001 inch larger than bore. IE .309 inch for .308 calibers, and so on. I use mostly straight wheel weights. Although adding tin makes the cast easier. Start with a completely clean bore for best results. Keep your velocities below 1600 to 1700 FPS and you shouldn't have leading problems. Harder bullets can be pushed faster. Paper patched bullets can be pushed much faster. Round nose and flat nose bullets seem to work better for me than spritzer types. Ive never used cast bullets on big game, but I wouldn't hesitate because i've killed deer with the .30-30 with 150 grain bullets. I'm sure that a .30 caliber 180 to 200 grain bullet at 1800 to 2000 FPS would be more than adequate up to 150 yards. Cast bullet shooting is more enjoyable. Muzzle blast and recoil are substantially reduced. I don't mind the heavy recoil of my larger rifles, but I don't relish it. Also, with todays prices, you can either save and lot of money or shoot a lot more. Look on EBay for used equipment. Even buying new equipment, you could get set up for less than $600 to $700. But with powder prices, in a .30-06, you could use 20 grains of 5744 or Buffalo powder instead of 56 grains of 4350. You could cast cast bullets using scrap wheel weights or you can buy jacketed bullets. Savings in powder and bullets are substancial and neck size and anneal the necks occasionally and brass will last for many firings. I also think that keeping reduced load fired brass separate is a good idea. Good Luck!
