I saw this and wow its zippy. 5,220.8 fps. They say that they maxed out the garmin c1. So whos gonna build one and give it a go. This tickles my fancy but not high on the list cuz my plates full learning still lol.
Baby steps. These will be the slow ones, 25 grain and will try to get 3800-3900 fps. Left to right conversion of 556 to 17-556 and final loaded(dummy round)
That’s crazy, I had a 22-250 that I loaded 40gr Barnes @ 4200. I would shoot song dogs and at a 100 you could hear the bullet hit before the gun going off. That barrel didn’t last long but damn it was fun, I can’t imagine 5200
