I had mine built about the same time Jeffe did his. Mine had a 25" barrel and I used RL-22 exclusivly. With 64.5gr of RL-22 I was able to launch a 100gr Nosler Partition at 3576fps average (shot through a Chrony F1). With 64.5gr of powder, the case only fills up to the base of the shoulder. I never experienced any pressure signs, but I've been told with these small overbore type cartridges over pressure comes on quick so I stopped at 64.5gr.

I sold the rifle recently to raise cash for a very expensive custom Mauser project I'm working on. It didn't start out that way, but I've let my eye's overload my wallet and unfortunatly a few things had to go . Here's a picture of my .257WSM, It was a sweet rifle!
