I have a collection of new SS barrels in a variety of contours/calibers/twists all manufactured by a variety of US marquee barrel makers.

Exactly what are you interested in?

I will second the opinion that you should discuss this with your gunsmith. If you trust him enough to build your rifle, then trust him enough to value his opinion. Internet "Experts" are a dime a dozen and will not be of any help if, and when, any problems should appear.

What is your O.A.L. on the 107's? Any problems with magazine length? Do you turn the necks on your brass? Who reamed the chamber for you? Do you mind if I PM you? I have been looking for some info and maybe you can help me.

On the 243 WSSM, the OAL off the “meplat” is 2.5095” using a 107gr Sierra Mk, off he “ogive” it measures; 1.9355” inches. As for magazine feeding, I have a Sinclair magazine block in it; I never thought about feeding them through the magazine; I don’t believe it would be a problem; the action had a 7mm WSM in before I re-barreled it.
Neck turning; I hit them just enough on the outside to make them round after sizing in Redding Sizer Die; After that, I put them into a Sinclair/Wilson expander mandrel. The reamer came from Pacific Tool and Gauge Inc.
The barrel work was done by George Vais in Boise, Idaho
If you’d like to pm, that’s fine.
