After what has felt like an eternity with waiting for components, waiting for the build, COVID, working away internationally, a "failed" first attempt at a build etc, etc, etc today I finally got to try out the rifle with my name on it. Suitably impressed and more than happy so far, cant wait to try it on something other than paper and worthy of its performance.
Initial loadings were developed referencing Quick Load and Gordons Reloading Tool, and I must say these modern tools are a great asset when starting from scratch. See comparison below and how close predictions were.
I did in fact assemble 12 x cartridges, firing the first cartridge offhand to assess how the rifle would feel so that one didn't pass over the chronograph. All subsequent shots were form the bench and recoil was certainly noticeable but definitely tolerable, almost enjoyable, and I really wished I had loaded more but with the future of Woodleigh where its at I didn't want to burn up too many at this stage.
For some reason photos aren't uploading at the moment. I'll post some when I can.
