Right now I'm thinking that whatever caliber I keep it in will be based on the x57 case to insure the rifle won't have trouble feeding the rounds.
Right now I'm entertaining the idea of building a Gew 88 in .338x57. It should feed well (not sure about length) and I don't think the pressure would be excessive with moderate loads. I think the .338x57 may be the best choice for this action for hunting in thick woods (won't be deflected as easily as a smaller bullet). What do you think?
I have an extra Gew receiver sitting around that I may actually try heat treating. I work in a metal shop so I could just sent the receiver off with a shipment to be heat treated very inexpensively to a Rockwell that I specify. I'm thinking something like 8mm rem mag might even be a possibility.
