Problem resolved

[Ben]

I have a Canadian Centennial 1967, Win. 94, 30-30.

The rifle has zero throat. None of my reloads that have bullets with a .300 , .301 nose would chamber.

Ian gave me the idea of nose sizing to fit the rifle. I have a Lyman 311466 that is plain based and shoots well in many of my .30 cal. rifles. I decided that I'd use this bullet with some nose sizing in my 30-30.

I ordered a Redding .298" bushing. Buckshot made me a nose sizing die many years ago that takes the Redding bushings. The bushing arrived today. Bingo !!!!!!!! Problem resolved.

With the OAL you see below, my rounds now chamber very smoothly.

Next item of business is to send them down range and see how they perform.

Mountain Molds makes nose dies too, but they're expensive and don't take the neck bushings. Sounds like you still need a 311041U....

I'm hoping this system will work.
For $16.00 ( the cost of the Redding bushing ), I can't complain.

Fascinating Ben, I too have the Canadian Centennial 67 in 30-30. I thought mine was a fluke, no throat whatsoever. What you see in the first picture is the beginning if the rifling, case mouth right against that edge. Photo through a bore scope.



Below is SAECO #305 tapped into the rifling from the breech. Needless to say it leaded horribly, even jacketed bullets had to be deep seated.



I had my smith run a throating reamer in it and it shoots well now as long as I size .311+. It has a good bore with no tight or loose spots but groove depth measures a couple of tenths under .310", not 308".

I wonder now if all of those Centennial models left the factory this way?

Rick,

We KNOW that 2 of them left that way ! !

I cleaned up an unfired attic queen that was the same way, virtually no throat and something near .310" groove dimension. It was a commemorative 66 of some sort, gold-plated receiver and blued octagonal barrel. This one would take the 311041 ok, but barely. One plus was it shot bugholes! So that's three of them that left the factory that way.

I'd like to get this one throated like you did one of yours.
