Need some help guys. If anyone on reading this thread has a long barrel 223 Semi-auto (24-26" barrel), I'm curious how fast you can push a 69gr SMK/TMK accurately (~1/2-3/4 MOA CONSISTENTLY).
Swapped my AR barrel for a new Valkyrie 26" 7.5T tube and I'm at 3180fps with 27.8gr CFE223 and it's shooting .3"-.5" 4- shot groups. RE17 is faster but is a PITA to meter and tricky to tune. The same bullet in my 18" 223 Wylde was 2730-2750. But it's not apples to apples because if the barrel length. So I'm seriously asking to see if a LONG 223 can keep pace with the 224V. I've yet to see an apples to apples comparison (same barrel length and same bullet tuned for each barrel). Most of the time, it's an SPR Mod2 77gr 18" 556 (or similar) vs a 90gr hypothetical 224V load from a 24" barrel that very few people seem to have gotten to shoot well. That's like comparing a pistol AR to a service rifle built for F-TR.
I bought this barrel to prove the Valkyrie wrong: I mean seriously, it cant be THAT much different. But now with real data, actual cases to measure, running through Quickload and testing in the field, I've nearly flipped my position.
I'll be shooting this Valkyrie against my 20" Kreiger from 200-1100yds for personal test because it's the only reference I have. I'll shoot the same bullet (69 TMK) as fast and accurate as each barrel will allow.
Hopefully some of you can help with data from longer barrel 223's.
