2 is a couple, 3 is a group. Bump your load up to 24.8 grains H335 and watch your overall length.

I have a DPMS A4 and it will shoot 5 shot moa or better with hand loads. The 2 loads I worked up are 24.8gr H335 and 25.8gr Varget. Both with Hornady 55 gr fmj. The load you are using was not consistent. The only mod to mine was I replaced the front sight with a quad gas block. The H335 load was delivering .5 moa in a Savage 10.
