I have a classic Winchester in 300 RUM. I would like to have it converted to the 404 Jeffery. If the internal threads on the action are not straight, I would want those single cut straight.

I would like to go to the one piece bottom metal made by PT&G. I'm willing to buy an aftermarket magazine box, and bottom metal as well. Thanks for any leads.

Bro' Dart,

I wish I could help, but my 'smith is doing only face-to-face business now. Too many internet dumbasses wasting his time.
I am not allowed to offer his services anymore.

But that is a simple job that any smith worth his salt can do.
Just make sure your barrel, reamer, dies, brass, and bullets are all compatible.


Adding some parallel-sided free-bore (PSFB) to the "leade-only" throat of the CIP chamber is a good idea for compatibility with all bullets.

PSFB diameter: .001" greater in diameter than the bullet diameter.

PSFB length: No more than the diameter of the bullet. I think that 0.3000" would be sufficient to "Weatherby-ize" for most bullets.

Leade angle: 1.5 degrees

Starts with decision on barrel maker ...

Dennis Olson, pLains Mt. can do it, not sure what his schedule is..Give him a call: 406-826-4790.

Hi Bro' Rip,
I was thinking of McGowan. You had good luck with them. Krieger would be my second choice. I can live with the slow twist if I have to.

We think alike. I put in a .300" freebore and 1.5 degree angle of repose on anything over .375.

I will probably have Greg Tannel straighten any wayward actions to start with. This neck of Idaho is hurting for decent gunsmiths. I might try Mr. Olsen over in Montana.

Are you dialing back on the medicine slog yet?

If you ever pass through Idaho, I will teach you how to cast a fly.

Give Wayne at AHR a call. He just finished a M70 404 Jeffery for me and it is outstanding.

Cool.
I just bought a take off stock for a CZ Magnum from him. Why would anybody swipe my stock but leave the Riby barreled action?????

Wayne is easy to deal with.

Thanks for the lead.

I would suggest Mark Penrod. He does excellent work and is great to deal with.

Thanks for that pointer. Mark certainly knows how to make a Winchester sing.

Yes he does. More like he knows how to make any rifle sing!

I agree, Mark Penrod is excellent, I would go with a Lothar Walther barrel every time.
