Early Big Timber chamber question
I am looking at a 45-70 Business rifle made at Big Timber - probably in the early 80's. The serial number is in the 6500 range. The barrel is marked Old Reliable, and C. Sharps Arms.
Does anyone know what this rifle's chamber/throat situation would have been? Freebore? If it is one of the long freebore rifles I will pass on it.
The rifle will have to be completely restocked as it is. What might the current cost to be to stock a B rifle with a standard military butt and round nosed standard wooden fore end, as per originals?
Thanks
Ryan

Re: Early Big Timber chamber question
At the end of the chamber there is a very distinct bored smooth area bigger than the chamber before the rifling. It can be anywhere from 3/16 to an extreme of 3/4 inch.
Looks like a wide ring in front of the chamber.
And not all guns have them. I had to ask specifically for the one in my fifty i got in the early 80s. And they asked how long the bullet would be and reamed it accordingly.
I also have an old 50-2&1/2 that does not have it, and they are within 75 serial numbers apart.
Does this belp?

Re: Early Big Timber chamber question
ya can always ream it out further to make it a 90, 100, 110 too. Did that to my dads rifle as his had .5in of that freebore in it. shoots very well now that its a 100.

Re: Early Big Timber chamber question
Did the barrel have to be set back for the longer reamer to clear the free bore section or was it simply a reaming job to the larger chamber?

Re: Early Big Timber chamber question
Mike you can do this with a throating reamer with a proper fit to the existing chamber wall. I did this to a Pedersoli turning a .45-70 to a 2.4

Re: Early Big Timber chamber question
Would it clean up the free bore if you ran it out to .45-90, .45-100 or .45-110?

Re: Early Big Timber chamber question
depends on how much freebore there is. Dads had a tick over .5in so now he is able to seat greasers out (if he ever shoots them again) out a bit further. From what ive seen most are around the .5in mark so a 2.6 from a 2.1 should take most if not all of it out
