So I cast for and shoot several handgun bullets, but have never cast for or used cast bullets for rifle cartridges. Currently casing 9mm for semi autos, 38spl for a snubbie, 357 for a 6in barrel, and 44spl and 44mag for a 20in barrel henry rifle.
I have a 30-06, and I ordered the lee C309-170-F, 170g flat point mold. I will be powder coating and gas checking. Planned to size to .309
I understand you cannot push cast bullets at the velocities I am used to with jacketed bullets and am limited to about 2200fps on the top end. These loads will be for fun, punching paper, at about 100yds, and letting the kids play with the big bolt gun.
I would prefer to use a powder I already have, but I understand I may need to add a new powder to my lineup. With that said, I don't want to buy multiple powders, I am hoping for 1 powder, work up a load, and shoot. I currently have Big Game, BL-c(2), CFE223, H335, H110, Lil Gun, HP-38, AA #7, and Power Pistol. I have had great luck with Power Pistol in my 44spl loads in my 20in barrel Henry. Other powders seem to burn up too fast, or not produce enough gas volume.
I have done some reading on mouse fart loads with Unique and 2400. I also have the lyman cast bullet book that I am still digging into.
Will any of the powder I have be suitable? If not, is there one powder that will be most likely to work well as a beginner with cast bullets in rifles?
