"Take down rifles can be made with exchange barrels in different calibres, here is a list of some useful combinations:

338 Win / 458 Lott
300 Win Mag / 375 H&H
300 Win Mag / 416 Rem
8 x 68 S / 9.5 x 66 ( 375 Westley Richards)
270 Win / 9.3 x 62 270 WSM / 325 WSM"

Not wanting to take out anything of a gunmaker's claims as to usefulness - what the heck is 9,5x66 (.375 Westley Richards)? Never heard of that one!
