Sweet! I need to finish my turk action I have sitting around.

Why the modification to the rear base? All of my Turks are large ring actions and use the usual 45/46 combo. I have one which I reduced to small ring dimensions and it will use different bases. GD

Nice looking Turk sir. There was a guy here at the fire that had built several sporters on Turks, not sure if he still lurks here or not. Dont remember his name

Question. I too used an M38 for the base of build.

Are you getting any feed issues?

With mine if I don't...rack the bolt with authority, the claw doesn't pick up cartridge head and I end up pushing the cartridge into battery without being able to close the bolt.

A professional gunsmith tells me it is customary to shim under the front #46 base with 1903 Turks, not boring bar trim the rear #45 base.
He also says it is customary to fit the #45 to the hump, not modify the hump to fit the #45 base.
I am just an amateur making it hard on myself.

I made (4) dummy rounds with 308 brass necked down to 260, and 120 gr NBT bullets at 2.8" OAL, the max that will chamber.
I cannot get it to malfunction at feeding or ejecting.

My bottom metal has 0.015" clearance under the receiver with my pillar lengths compressed.* The front of my bottom metal mag well has a 0.2" thick spacer I made to keep the ammo from going forward and getting trapped under the feed ramp.

* that means I had a lot of Walnut to mill, file, and sand to raise the bottom metal so the pillars would be compressed by the action screws..

I have used the Turks for 7mm-08, 260, 6mm Rem, 243, 6.5x55, and 7x57. All of these fed fine. In fact, the 260 and 7mm-08 fed so well, it was easy to think the bolt didn't pick a cartridge up.
As far as bridge height and scope base height is concerned, I have seen no reason to deviate from the LR 98 bases. I have either just removed the hump or have slotted the hump to accept the base.
One I have now has been reduced to small ring configuration but with the extra metal left over the right raceway; like on a Springfield or Enfield action. It may become a 308 or it may just be an 8x57 (I have a Shilen 8mm barrel under the bench). GD
Let’s us know how the guns shoots. Interesting project and the work looks great. A Turk isn’t nice enough for what you did. I would have done a husky Mauser, or an fn commercial. But that’s me and this looks like it was meant to be a fun project, Which I certain can respect.

The work is its own reward so well done. I think that rifle will serve you well. You won’t need much of a recoil pad so I suggest something a nice solid rubber pad in a color that suits you.
I love my 260.

On my Turkish 260, I extended the throat to allow me to seat the bullets out further and take advantage of the longer magazine. Also, I had some 160 grain Sierra semi-pointed bullets which have a very long bearing surface. I think this is the very best of the 160 grain bullets BTW. Sadly, they didn't sell enough, I guess, so they were discontinued. GD

I have a Manson 7mm throater and wanted a 6.5mm throating reamer for this project.. but could not find one on the shelf..

You got me to try harder in Brownells search. There are Clymer throaters.
I just ordered one.

They sell throaters, but are out of throater holders.

So I made a throater holder.
It is a piece of tubing that I bored out to 0.2495" with a tiny carbide boring bar.
Then I drilled and tapped the tube for a 4-40 set screw.

After throating, I can now chamber a 3.1" OAL 260 Rem dummy round instead of a 2.6" with 120 gr NBT.
This should give me an extra 200 fps.

Shot 6 rifles I built this year. The Turk did the the best today with a 1/2" group at 100 yards.
