Home Forums Hunting & Shooting AR and Tactical Rifles 24HC Black Rifle Challenge Thread

I like how your rifle is shooting the 77TMK load. My Noveske was shooting it about that well. I only ran them up around 2650 fps though, as the max fps listed with RL15 was 2600 fps. As we know AR Comp is just a re-formulated RL15, but most say you should reduce book charge weights by 5%. By doing that, your max book load would be somewhere around 22.8 gr's... One thing I noticed when I was working up loads with AR Comp was as I approached 22 grains of powder with my AR's, I had surpassed the 2,600 fps mark the book suggests as max:



My bolt gun has a slow barrel compared to my AR's and I was up around 2690 fps with 22.3 grains of powder:


Its funny though, AR comp is listed in the bolt gun data:


The predator bolt gun is liking the 22.3 gr charge wt of AR Comp though:
