Ok, so im new to casting bullets. I got an RCBS lube sizer, what size sizers and top punches do i need for sizing for:

.308 cal
45 colt
38 spl

also, is 45 colt and 45 acp the same size moulds?

Top punches depend on bullet shape.

.45acp is usually sized .452

.45 Colt sizes can vary a bit more, I don't have one but expect either .452 or .454 depending on the pistol. Hope someone more knowledgeable can chip in on the .45 "long Colt".

I'd start with the .38 special myself, easy cartridge to reload (I'm told, don't have one yet) straight walled cartridge, headspaces on the rim, tons of reloading data. Does not use a lot of powder or lead.

Top punch determined by bullet shape, diameter determined by slugging your bore. A 45 Colt can do OK w/ 45 ACP bullets, traditional Colt bullets ususally not a good idea in a 45 ACP.

308 rifles can stand 309-310

38/357 a good starting point is 358-359
