I'm hoping to get 3600-3700 from the 69s, with the longer tube and 2000MR it is attainable according to quickload. I haven't run the 90s through QL but will tomorrow. My 223AI does 3100 with 80gr berger VLD in a 23" barrel. I'd imagine with 10gr+ increased case capacity and working on the heavy end of the pressure spectrum i should see 3300-3400+ from the 90s. I guess we will see when everything plays out.Welcome! 3400 FPS with that 69 gr bullet should be easy. The 90 gr bullet is probably going to be 3200, maybe 3300 FPS.
Good luck, you ll love that 22-250 AI
I'll not be pesimistic in your journey to achieve 3400 from the 90s. I hope you get there. My 30" 22-250AI with Reloader 15 gave 3320. Possibly RL26 could have made it, I don't know. The 80s get me to 3550 so I was positive I'd get 3400 from the 90s. May simply take a different powder to make it happen.I'm hoping to get 3600-3700 from the 69s, with the longer tube and 2000MR it is attainable according to quickload.
