22 ARC 75 ELD-M Factory Ammunition Velocity

[VASCAR2]

I’ve experienced an issue where .224 50 grain PPU pointed soft point bullets come apart in 1:7 AR-15 but shot fine out 1:9 twist barrels. I shoot a lot of 55 and 69 grain in my 5.56/223 1:9 twist AR-15’s. My 5.56/223 1:7 twist shoot those plus I also shoot 77 grain SMK. I haven’t checked every manufacture but noticed some 22 ARC barrels were 1:7 or 1:7.5 twist. I still haven’t seen the Hornady 22 ARC load data.
