While flipping through the latest Sinclair catalog I saw that RCBS has come out with the Rockchucker Supreme that's supposed to be for new/longer cartridges. When I buy a .338 Lapua, should I be good with the Rockchucker I bought back in '99 or will I have to buy an updated press to reload for that cartridge (no big deal--factory .338 LM isn't cheap...).
