I completed load development for a Remington SPS Tactical about a month ago. The charge weight is above Hornady's max, but the bullet is seated further out as well. I have no pressure signs, but work up to it. 25.5 Benchmark @ 2.260" OAL shot a 0.5 MOA group at 100 yards, but the velocity spread was 80 fps. 26.0 Benchmark @ 2.270" put 5 shots into one hole with single digit ES.I just completed a 223 build using a CZ 527 and 1-12 pacnor sporter barrel, would like to try the 53gr VMAX, if you have any load info you would be willing to share, it would be appreciated, thanks and hope you all have a Happy New Year!
