A fellow CGNr sent me a cartridge adapter for 7.62x54R to 25. They must be available.
So I could put 7.62x25 in my Mosin Nagant ?????? what would happen in my SVT-40? (crossing the streams......omg don't cross the streams)
Where do I get one of these magic tools and how much As* do I have to sell to get one?
Any .311 bore barrel could be fitted to a receiver and chambered in that. Ask a Smith.
Might be a fun mod for a shout-out .32-20 lever gun.
Is the 7.62x25 a 311 cal, or 308? Wiki says 308 cal, but i dunno if that's right.
The bullet diameter of the 7.62x25 is .310. In my experience, in my rifles it poses no issues. Think about it for a second. This isn't a cartridge that creates high pressures. Admittedly it develops high pressure for its cartridge class but when you're dealing with strong rifle actions the slight pressure rise is inconsequential.
Back in the day when many of the firearms chambered for this cartridge were manufactured I'm willing to bet the off the line manufacturing tolerances were within .002 in. or more.
I was more thinking that a .308 bullet from a .311 to .314+ bore would provide poor accuracy and the novelty of the whole idea would wear off mighty fast.
OP, I looked at the reviews of the insert that was posted, and the vast majority of them say its more hassle than its worth. If you are willing to put some time and effort into polishing the insert so the 7.62x25 cases dont get stuck then they're not terrible seems to be the general opinion.
I would love a cheap little 7.62x25 rifle (bolt, semi, even a break action) for plinking, but the hassle of an insert wouldn't be nearly as much fun. (At that point, I'd probably just want to shoot my 303 or 7.62x54r rifle).... With the break action comment, anyone making shotgun adapters for this cal?
If you do a bit of shopping around you can pick up a Spanish Destroyer with a crappy bore and have it relined with an insert chambered in 7.62x25 around the $500 mark. The bolt face won't have to be opened, the extractor is fine as is and the mag is good to go. Tradex had some spare mags for cheap as well. I modified my mag well to accept Tokarev mags without any issues. The big thing is setting aside the time to do it right. Nothing difficult about this conversion.
