Re: 243 wssm build ??????
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.
