I've decided to stick with the RAR for now. I ordered the AI magazine conversion from Ruger, and I'll have the barrel cut and threaded at 20". For the minimum investment, I'll get a chance to try out the .308. Looking over my notes from when I originally shot it, I was averaging about 2825 with TAC. 46.5 of Varget was giving me pressure signs before I chrono'ed velocities.
