Hello there. Anyone got some groups at 500m
I'm interested in what u guys are getting.
I'm running 55gr amax out of a 24inch howa at 3000fps.
My groups today where 0.93 MOA.
I will give pics later
Cool.

You should be able to easily get 3250fps, as that is where the highest node is with 55gr bullets. Pressure will be in and around 50K psi and the extra 250fps will help with trajectory and wind shift.

Roboman, if I were you and looking at shooting longer range with the 223 I would look at the 73 or 75 eldm or 75 Amax at around 2950fps.
This is of course if you have the newer Howa with 9 twist barrel.

Die Yanks skiet daardie groot rotte van hulle tot op 500 treë met die 223's.
