I don't have any experience with DPMS, but I do have a Remington R15 in .204. I wasn't satisfied with groups using factory Hornady 32gr vmax, so I started handloading for it. Long story short, I went through a lot of different powders before I finally found 2 it liked since playing with COL wasn't really an option with the mag. I also tried 35gr Burgers with no luck. It's a sweet shooter, but took a long time to get it there. Settled on CFE 223 because of the velocity (9 shot ave. w/ my chrono was 3882) with a 22" barrel.
Rifle came with a Remington 5rd mag, but when going to higher capacity mags I also ran into the pmag issues and am currently using Lancer mags.
