Re: New Rifle - 223 Ackley Improved
I put one together for my father-in-law with a 24" douglas 1-10 twist , I'm not certain what the load was but R-7 gave the best velocity and accuracy with the 40gr V-max and I remember that 4000fps was not hard to reach , I believe that the accurate load was around 27grs. This barrel was fire lapped to try to smooth it out. After several hundred rounds it was rechambered to 22BR and shot 55gr V-maxes.
