In South Texas also and I am very interested in loads that are working in shorty rifles. I am working on my second 6mm Creed build and am not having luck with H4350 and berger 105s. This one is ARC Nucleus, Proof carbon 16.5", on a Bravo stock with Vortex 5-25 and Harvester Suppressor. My first with a 16'5" Criterion I had great success shooting 1/2 MOA out to 600 yds with nodes at 41.1 and 42.5 of H4350. I am also curious about running faster powders. I saw a post regarding RL26 in a shorty, is this powder faster? I have a gazillion questions.......
