Sidewalls would be about 0.1395". That would probably suffice for a cartridge like a 9.3X62. I wouldn't want to go below 0.125" for any cartridge.

Dear Rob, the usual reboring job in such a case (ahem) was the 9x57 Mauser. A good cartridge for which Winchester (Mod. 54) and Remington also did chamber rifles.

9,3x62 would be problematic, IMHO.

Carcano

I have been given a fairly nice sporterized M98 that was brought back from Germany after WWII.

Stippled front ring and barrel shank, modest engraving, butterknife bolt handle, double set triggers, floorplate release, full rib on the barrel with one standing and one folding leaf site.



It's currently an 8x57 but the bore doesn't look at all good, the rifling is almost gone.



Because of all the extras on the barrel I want to have it rebored rather than rebarreled. The muzzle OD is 0.645. Is there enough here to go to a 9.3x62?



From looking at drawings of the two cartridges it looks to me as though this should not require the barrel to be set back, that the reamer will just enlarge the existing chamber, am I right?



Should it feed properly or will it need more work?





Thanks, Rob
