I have a AR pistol 5.56, 5 1/2 inch barrel 1-8 twist, wanting to get info on which bullet weight & powder to get best stabilization at fifty yards and out. I have different powders for pistol and rifle, but need info on both. For example, I've used Trail Boss for 55gr, but keyholes at about 25ft feet, but won't cycle the action. My regular loads won't stabilize past about 50ft. Just so everyone knows this gun is just for plinking, no hunting, having fun. I'm thinking heavier bullet, maybe 62 to 75 gr might work?
Thanks in advance for the help
