Cal 4 ID


I have a problem about ID this case. COL is 98mm, diameter is c26,5mm and it is rimfire. Any information would be welcome.



Is it really RF, not Bar-Anvil primer? Probably unfinished 1" Gatling canister case…or?


Thanks THV, the diameter is 26,5mm and perhaps it is to large for a 1" Gatling, I don’t know. It is a NPE


Not sure what diameter your mentioning “c26,5mm” but my loaded 1" bar-primed canister measures 26.02mm at the head and the rim is 29.18mm. So perhaps yours is too large?

case length is 102.76mm so yours is a bit short.
