Neither do I. Herco 2400 (before bought by alliant) was designed for small bore rifle cartridges, some good examples are 22hornet, 25-20wcf, 32-20 but later figuring out that it was better suited as a pistol powder for cartridges with a need of a slow burning powder, particularly magnums. And like all slower pistol and shotgun powders it has an optimal performance in rifle cartridges using a cast bullet. The only cartridge I shoot jacketed bullets with in a rifle is the 30 carbine. I don't see using 2400 in the 30-30 with jacketed bullets highly unsafe to an experienced reloader, but not fool proof and I don't recommend it. If your not hunting anymore and simply want to target and plink, keep the 2400 as it is an excellent choice for cast bullets in that cartridge, but either buy or trade your jacketed bullets for some cast. your bullet options are between 150-220gr gas checked or plain base. There cheaper to buy, takes less powder so it will go further for you, and loaded properly just as clean and accurate. If you need some sources to find those types of cast 30cal bullets, and some starting load data for what you've chosen, private message me and I'll help you.
