I just got a new barrel from Paul and took it to the range yesterday. It's a 16" 223 Wylde Bartlein barrel, standard heavy contour. Platform is a factory DDM4V7 lower/upper/bolt.
No load development, just used some ammo I already had on hand. 77 SMK's 23.2gr XBR8208 loaded to 2.26" in Lake City brass with CCI 450's, on a Dillon progressive. Fired 15 shots to get roughly zeroed and the barrel fouled, then shot a 7 round group. Side note - this was at 100 yards with a 1-8x power scope. It's super hard to aim precisely without magnification, I'm used to shooting with my 7-35x ATACR.
6 shots in under a half inch, with the 7th shot flyer making it a 3/4" group. The black aiming dots are 1/3" diameter.
Super happy with the results, would gladly endorse him for future work.
