Rechambering Factory barrels.

[kenbev]

I am thinking of rechambering some NEF/H&R barrels to other calibers. What barresl can be rechambered and what can they be rechambered too. I only interested in using factory ammo, so the odd calibers are not for me....

They can all be re-chambered as long as you pick a cartridge that it larger in all dimensions than what you start with.  Larry

Well...almost all of them this way...the short magnums..ultra magnums..or regular magnums are too much for the Handi's..and most smiths won't rechamber too them..then you'll have the ejector/extractors to work around as well..but as Larry said..you have to go larger than the original cartridge..

Ken:
If you want to be able to fire factory ammo, that will limit you. Here are a few. I'm sure others will offer others. The easiest ones are where the ejector does not need replacement/modifications. IE: rimed to rimed or rimless to rimless.

22 Hornet > 221 Fireball

22 Hornet > 225 Winchester (This is a good one. Did it. Works great.)

357 Mag > 357 Max

357 Mag > 35 Remington

30-30 Win > 30-40 Krag

30-30 Win > 30-30 AI (Controversy aside, this one works great. Its the same as rechambering to a 30-40 Krag. It headspaces on the rim like the Krag, and has NO crush fit isssue. And you can still fire factory 30-30s.)

7.62 x 39 > 7.7 Japanese, 303 British or 7.65x53

44 Mag > 445 Mag or 444 Marlin

Hope this helps you get started. There is a lot of fun in shooting a unique caliber.

don't forget 17HMR to 17 Remington!

or the 7.62x39 to 7.62x 54R

The list goes on and on , right now i am having a 22 mag bull barrel done in 32 H&R mag and the next one will be a 240 congo .

Granted the congo is not a factory round but the 32 is and there are all kinds of factory ammo still being made that a handi can be chambered to .
