Savage M340 re-barrel question for the experts.

[bigbrad53]

From what I am reading, the shank is smaller on a 340. Somewhere in the .850-.875 range. A 1.060 barrel could be turned and rethreaded. Of course, the straight section would be longer once turned.

A doner barrel would have to be shortened on chamber end, threaded, rechambered, and contoured. All could be done by any one who does barrel work.

So true about the "Just because we want to". Gets me in trouble all the time. I also have a soft spot for it as my Dad had the Coast to Coast Hardware version in 222. With open sights it was a tack driver.

I have a NOS 30 carbine super blackhawk because I had parts laying around and thought why not.

Thing is I've never seen or heard of a 25-35 bolt gun. More that enough reason to do it for me.

I'm loading my 340's and 99 with spire points, 4 grains over manual max with NO issues. Only other bolt guns in 30-30 to build one on are Winchester 54 and 788 Remington, good luck with that. Both are selling for way too much money!

I have looked at 788 auctions and holy cow the prices they bring. I will keep those loads in mind.

If you do go thru with project let me know I have the reamer for 25-35 imp

If I do this project it will be late this year or early next year as I already have 3 projects in the works. However I will need to buy ammo right away as Hornaday currently has a run of 25-35 Leverevolution ammo out.

We think alike.

222 magazine, bolt face and extractor are too small. Any gunsmith who does barrel work can do this. Contour, thread, chamber, set head space, and cut extractor notch. Thought about doing this for years, just never got around to it. Early 340's weren't drilled, taped for mounts but are easily done.

Both of mine are drilled and tapped for side scope mount. I think this is going to happen.

Never could figure out why Winchester didn't just neck down the 30-30 to 25 caliber. It's got more taper and longer neck that a 30-30 and they called it a 25-35? Go figure.

If nothing else loaded with spire points and a slight bump in pressure should make a fun truck gun. These actions will hold more pressure than SAMI spec as they were available in 224 Winchester. I've never heard of anyone blowing one of these rifles up, just use some common sense.

Interesting thread! Back in the early 60's my brother had a Savage 340 chambered in a Hornet and I had one in 222! Both had scopes on them but I don't remember how they were mounted! I'm into pretty rifles and always have been, so probably traded my 222 for something prettier!

There is a side mount type scope mount that you can buy. It is true that they might not be the prettiest rifle but they do seem to shoot pretty well.

I've got a project started for my 30-30 Model 99. Start with 225 Winchester specs, put a 30-30 rim on it, shove the shoulder forward to make neck .224 inches long. Then lengthen case to 2.06 inches long, throat for 70 grain bullets. 225 High Power, my version of what Savage could of done.

I have 2 Savage 340s in 30-30 and kicking around the idea of re-barreling one of them to 25-35. Does the 340 use the same thread and barrel nut as the 110? Could it really be that easy? I'm assuming I will need a 25 caliber barrel blank of the correct outside diameter and have the receiver end threaded as wel as have it chambered for the 25-35. Is this even possible? Or should I just keep things the way they are? Thanks for any thoughts and insights you may have.

Possible and expensive. It would be to your advantage to buy a rifle in the caliber you want or close to it. A good barrel today is in the $400.⁰⁰ and up range. A great gunsmith will charge about the same as the barrel cost to thread, chamber and install correctly.
Back a few years before Covid that price was $250.⁰⁰ for a pre-fit barrel and $450.⁰⁰ for a custom barrel installed. If you don't care about the cost look up a competent gunsmith and have it done.
