Build #8 - 7x57 Mauser on a Rem 700 - Lightweight Hunter for a deserving Veteran


Sawtooth Rifles - Build #8:  7x57 Mauser - Light Weight Hunter


Updated field report at the bottom.

We volunteered to build this rifle for a deserving Veteran.  Funds were donated by some great guys at the 24hourcampfire.com forums.

Spec's:

Action:  Remington 700 LA
Barrel Blank:  McGowan, 7mm, 1:9", Rem Mt. Rifle contour, finished at 22"
Stock:  Bell and Carlson, reworked and painted by "Karnis"
Bottom Metal:  Rem BDL Aluminum
Trigger:  Tuned Remington
Rings/Bases:  Talley Lightweight integral mounts.
Optic:  Leupold VX-2 2-7x32
Finish, Metal:  Sniper Grey Cerakote
Finish, Stock:  OD Green Duracoat, by Karnis

Parts.  And it begins.


First issue, The talley bases/rings are a no go with the little Leupold on the long action.


Next Issue.  Fit of the PTG bottom metal on our stock is not that great.  Some work on both parts may make this suitable.
Rem bottom metal fit.  Much better.

Receiver about to be re-machined.

Blueprinted receiver, nice surfaces and threads cut true to the bolt's axis.


Barrel blank on the lathe, not much to hold on to on this one and have enough sticking out to work with.
A few minutes later, we have it turned down, threaded, and the pocket cut for the bolt nose along with boring out the first inch of the chamber to save time with the reamer.
Reamer time.
I wish this were only a few minutes later...  but we finally have a chamber in there.
Receiver snugged up, bolt closed, headspace gauge hiding in there.
Finished on this end, remember me mentioning not having any extra length?  I faced off so little on this one that the stamps are still showing.


With the barrel and action together, we can finally see how it fits in the stock.  We'll get to the crown after a bit...

Just some minor inletting will be required just in front of the recoil lug




Dialing in the bore on the muzzle end before cutting the crown.

Lewis, making this one special.

Baking rifle parts.  Sniper Grey Cerakote

Prepped for a bedding job.

Epoxy added.  Why is this part always scary?.

Epoxy on the other half.

Builds expensive rifles, still plays with play dough.
Hopefully it comes back apart!

Apart!  That is always a releif.  Just a little bit of cleaning up now.

Ready for assembly.

All together.  This is a sweetheart of a little rifle.

An update from Brent's post about his first day out with the rifle:

Well I rounded up some ammo, found a good deal on some 139 grain factory rounds. Finally had some free time so I escaped up to the mountains to do some shooting. Got it on paper at 25, then moved out to 130 yds and shot this group.



Just under .9" at 130 yds! Spent the rest of the time banging steel at various distances. Suffice to say I LOVE this rifle, its a joy to shoot and handles great. Think it's gonna see alot of use hunting in the future! A very sincere thanks and gratitude to everyone who helped this happen!
