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.

Here is a link to see velocities related to barrel length for the 50bmg.

Each gun and barrel will be different anyway
