Need to find a diagram with the case dimensions for this caliber. 10-4 that it is a wildcat. Am considering rechambering one to .17 Mach IV and trying to figure out how much barrel set-back it will take.

So far my google searches have ot turned up any such diagrams.

Matt,

May I ask what rifle/action/barrel combination you're thinking of re-chambering?

Thanks,
Kevin
