.358-GNR Question...

Just got a great bye on a .357-Herrett, and would like to re-chamber to .358-GNR (.357/445 Supermag), there is a 0.14" difference in the overall case length, but since both are rimmed cartridges I don't think that the difference would matter?

Welcome your thoughts...

PS: Who has data on the 30-Raptor Cartridge, have the barrel and dies, just need reloading info...
