I'd be interested in seeing what your final load comes out too. I am waiting for my 6.5-06 AI bbl from McGowen so I can finish my build. I am having an 8 twist in the bbl as I want to shoot 140+ in it. I have talked to a local guy that is reloading his with RL22. I also saw one post online where a person settled on Retumbo with good results. I planned on building this rifle last year but then life got in the way. Keep the posts coming.
