okay so it may be the case that I'm NOT THE MOST WELL VERSED GUY in the world of cartridges, but I don't have a clue what a 59 case would be from.

secondly dose any one know anything about this cartridge. I'm looking for uses foer a gun that a "gunsmith" re-barreled. unfortunately he used a 257 barrel where he should have used 264 barrel.

so now I'm re-cambering, or barreling yeah!

I really only interested only in starting a thread about the 6.35x59. there is already plenty if info out there about the Bob so please lets not go that direction.

hear are two link's, where I found the cartridge.

any help would be greatly appreciated.

my best guess is it's a slightly shorted 30-06 case. the 06 case ought to be 63mm, so why the shortening. could it lose 4mm in length during neck down.

Seems its a 30-06 parent case (or 25-06, 270) shortend since the case head is .473. Might be designed for a specific legnth action where the 25-06 would be too long and still offer an increase over the .257 roberts.

Hi Peder 1979.
I think you better leave things be. 6.35 is the metric size for our .250 bore, or .257 groove diameter. You will need a G.S. to look at this puppy. It may be someone's take on the old 25 Neidner. This was in between the 257 Rob'ts, and the 25-06 Gov't. The logic was that with the powders they had in the 1930's, the Neidner was the ideal capacity for the .25 bore. It should still be pretty close in capacity to a 257 Rob'ts improved, but not interchangeable with it. The 25 ACP is still called the 6.35 Browning in Europe. Whoever did this one up, may not have had the rights to name it the 25 Neidner, in the same fashion that Mr. Gebby held the rights to the 22 Varminter. So everyone else went around him and called it the 22-250. Your smokepole may be just an end run around the Neidner name too. But I don't see where you mention what action you have it chambered in. There are some intermediate M-98's that won't quite take the 62mm long cartridges like our 270 Winchester. So a 25 Niedner knock off would be a good compromise. So, you may have an American wildcat cartridge with Euro metric nomenclature stamped on it's barrel. You also have a much better shoulder angle than a 25-06. And in the old days, the 25-06 was a good re-bore proposition, for shot out 220 Swifts, if they were chambered in a long action.
