I shoot mine... I buy surplus ammo when I can ( probably pay too much ) also convert 220 Swift cases to 7.62 x 45... ( have all the form dies, but there is still some machine work to do )
I ran across a company ( I think from Denver ) that sells loaded ammo made from 303 British
FIL collected Czech guns, since he was Czech... I added a VZ-58 to the collection after we inherited those guns...
I shoot the VZ-58 more, as it's chambered in 7.62 X 39... but there is nothing wrong with the 7.62 x 45 except availability... the VZ-52 is heavier, but I actually like it better
