I had Greg Tannel do the works on my Rem action which included double sleeved bolt, bushed firing pin, double pin lug and ect ect. At the same time I had Clay Spencer building me a second rifle which had the basic blueprint with surface grind factory lug.

Both rifles shoot way better than me. Listen to what your smith suggest. I asked Spencer about the extras which Tannel was doing and he said not needed. He could have squeezed an extra bill or two from me.

Some interesting blueprint videos on utube.
