I have a ruger american ranch chambered 5.56 with 16in barrel and 1:8 twist. I am trying to figure out what weight of bullet might give me the best groups and stabilization out further. I have but more then 300 rounds in the gun so im sure the barrel is most likely broke in. I have put cheap ammo and ammo up to $.55 ammo thru it. I never used soft points or deer rounds because i dont need that for a prairie dog. One ammo i found that I liked was hornady steel match ammo. Cabelas carried it and i bought a box. I believe the first box was the 75gr weight and i liked how it shot but never actually put groups on paper, it just hit on the dogs better. Bought another box and if memory serves me right it shot a little worse but i always told myself i was a fault. Last week I finally got to the range and put some groups on paper. Frontier 55gr fmj shot under one minute groups consistently. It seemed to like the frontier but another 55gr brand, monarch i think, did not do to well. Probably 1.25 MOA. All that to say, I believe front what I have tried to learn thru research is that my 1:8 twist should in theory like heavier bullets. I am going to go to academy and get some Black 75gr and 64gr ammo and see which the gun likes better. Am I headin in the right direction or is there a 55gr round that can shoot good. I do not reload so im left with box ammo and i want to find one round that can shoot consistently and i can buy for a while. For deer i will just get soft points and dial in my scope accordingly but I take far more dogs then anything.
thanks for any advice
