I put a bunch of money and effort into this rifle in Oct 2009.

I built two other 7mmMags at the same time with scrap parts, as practice, as I went along.

The Rem700 take off barrel on a 1908 Braz Mauser has very little time or money into it, and shoots just as well.

That was not per my plan.

Nice job! Looks like somebody likes 7 mags. as much as I do. My first one I used a Winchester P14 Enfield action and a stainless Sako 7mm Rem. mag takeoff barrel. I hunted with that gun for the last 2 years and it has accounted for several hogs, deer, and antelope. I'll probably break in the Turkington next year. It shoots a hair better than the Enfield and is about 3/4 lb. lighter.

 

How did you go about joining the winchester and remington barrels to the 1908s. Did you just tighted against the inner torque ring? I used a bushing on the Enfield which was frowned upon, but, has been holding up fine.

 

Anyway, nice job.

Nice work. How do you like that stock? I think that will be the next stock I buy.

[jverduce]

Very Nice! I'm jelous. You did a lot of planning on this one. It shows. 7 mag is a favorite of mine. It's a great cal.

I'm interested in how your trigger breaks and what your final let off ended up. I have a pile of military triggers and

would appreciate any advise which you might forward. Again, a beautiful rifle!

Roger,

I try to make the inner C ring touch the breech face when the shoulder touches the large ring.

If there is an error of ~ .001", I make it so the breech touches the inner C ring first.

That is because the inner C ring in cantilevered and has a little compliance, while the large ring, breech, and shoulder are stiff.

 

Ken,

The stock is ~ $200 wholesale and compares with a $400 McMillan light rifle stock, the High Tech Specialties [bansner] stock is not finished, painted, or perfectly inletted.

It depends on your situation, if that is worth it or not.

I put spray paint on it, and went hunting later that month with it.

I think it should really be an epoxy paint that is harder to wear off.

I cut off the stock butt in the power miter saw as per usual with a wood stock.

I had to screw and epoxy in a piece of wood into the hollow butt, so I had something to screw the limbsaver recoil pad into.

 

dogz,

The full trigger job on a Mauser fixes the:

1) force

2) take up

3) over travel

 

I find for big game hunting rifles, only the force is important.

To do that I:

1) Grind some off the hump, to loose the second stage of the two stage stock military Mauser trigger. In the pic below are two triggers side by side, with the hump ground off one.

2) The trigger spring is changed.

 

The pic has also been milled, Silver Soldered, drilled, and tapped for a take up adjustment. I would not do that to a 9 pound 7mmMag.

[Rojelio]

Here is my version of an adjustable mauser trigger. The screw through the spring is for adjusting overtravel. Zero creep is atainable, but, I don't believe is safe in a trigger like this. That creep is all the sear engagement that you have.
