I finally was able to get around to shooting my various factory hand loaded and reloaded 50 bullets in my new ar50. It was awesome.
In my 30 inch ar-50 at 20 yards i was able to achieve:
- w/ Factory match Amax magazine length 750 grain: 2760 FPS wi
- hand loaded Amax 750 grain w/ 215 grains RL-50: 2582 FPS
- I then loaded one with close to max charge 235 grains RL-50: 2785 FPS
I hope this helps anyone. It will at least give you insight if your using the new RL-50 powder. I have yet to try my h50 or us869. but i will updat the information when i get around to it. you can really feel the power increase just from the 8% +/- extra powder.
Additional info: temperature 79 F. 59% humidity. bullets and rifle were at room temperature for the first shot. the next two after being shot and in the sun for 10 minutes where considerably warmer.
