There are Cech barrels at .316 and a few late barrels at .323 but, most are at the above quoted figure of about .3205.
The problem won't be in safety but, in shootability. Lead needs to be atleast groove size or larger to shoot well.
That said, you always need to slug a GEW88 and the early GEW98's.
