It's a shame that the CZ550's don't have such a 'nice' bolt shroud such as the ones on the ZG-47 & disassemble down to individual parts!
Rugerboy you certainly will have a nice rig when all said & done! The 318WR maybe an odd calibre, but as TRX neatly puts it; if you choose reloading then the cost will be minor overall!
Will be nice to see how it turns out & the loads (ammunition) that you use.
Yep.....Homer's spot on as always!
