loiblbRunning out of wood lesson
I'm bedding the action of my 1910 Mexican in a bishop stock. The fit is spot on but for the fact that the breech of the barrel is becoming thin in that area of the stock. It will fit with careful work but it is much thinner then I ever planed it to be. This is a lesson on choosing the profile of my next barrel on a project.

z1rWhat diameter is your barrel where it meets the front ring?
Most folks make the mistake of using barrels as supplied or simply leave the cylindrical portion of the barrel too large.

butchlambertYou are correct Mike. I personally don't like the looks of anymore cylinder than I need.

brnomauserhow much meat is desirable round the chamber?
06 January 2013, 03:51
loiblbThe breech of the barrel meeting the action is 1.24" the front action ring is 1.29"+-.
All for a 7x57
As stated, lesson to be learned on this project.
The project will work but the little action needed more thought on the style of barrel

D HumbargerFor Mausers I like a OD of 1.150 to 1.750 in front of the reciever ring.

brnomauserThanks guys. z1r talked about turning down the straight section of the barrel, what wall thickness of the chamber area are you after there?

dpcdAs long as you have a small shoulder, it can be down to .970 and even less but it won't look good; look at Winchester featherweights. All that shank diameter is not needed for strength. REm 700s are 1.17 and Featherweights are .970. and taper down from there.

z1rOn a SR 98 1.150" is considered large. The two most common "mistakes" I see are too long a cylinder and too large a diameter of the cylinder.
That .970" number is interesting because when you disect it you find a chamber was thickness of .250". This is considered by some to be larger than needed but I tend to look at .250" chamber walls as my minimum. That said, you don;t always want to scale teh barrel down to bare minimum. there are advantages to having extra weight (in the right places).
1.240" is way too big for even a LR Mauser unless you are building a bench gun. No wonder you ran out of wood.

So that means minimum thickness for a 404 Jeffery would be 1.045" OD around the chamber? You say .25" is minimum, what is ideal?

z1rIdeal? Minimum plus whatever it takes to achieve proper blance & desired weight?
There is no one size fits all solution.
Ae you trying to build a super lightweight 404?
The Mauser thread diameter is 1.100" so, that minimum would not work in this case. Well, unless you use a military style shoulder or wanted a step down from the threads.
My previous post was directed at those folks who typically pay a premium price for a SR 98 action, then attach a 5 lb barrel to it. Makes no sense.
