Just curious if anyone had any pet loads they would like to share, starting load work on a 22" barrelled Ruger with a 1 in 10 twist tomorrow. Load development is slow in this heat, so I figured I'd ask. I have a pair of turrets for my Leupold CDS built for the 270WSM built around the 140gr AccuBond at 3033fps. I'm not sure I will get enough velocity to use them from the standard 270 with a 22" barrel, but will set up the chronograph just in case.
What powders would you recommend starting with to get top velocity from a 22" barrel? From the looking I did in my books I'm thinking of H100V, H4831, and H1000 to start. I also have RL22 and H and IMR4350, and IMR4831 on the shelf. The RL powders have seemed more temperature sensitive for me in the past so I'm going to hold off on them for now. I'm going for accuracy rather than speed, but I'll take all the speed I can get with accuracy and consistent velocity within safety limits. With a high of 95 tomorrow I'll keep starting loads light.
