I have to be honest, I am not impressed with these Berger 85.5 Hybrid bullets at all. Hugely expensive and performance is not great no matter what I try.
These 85.5 Bergers? cannot be tuned fully in an AR15. Simply too far past mag length...
To put this in perspective...go look at the 5.56 pages...look around until you find 1 load that was 1.5+ MOA? Having trouble? Because no kidding, you could load up total trash loads with Berger bullets in the 5.56 and you will STILL get near 1 MOA!! Not in Valkyrie...you load GOOD loads in Valkyrie using Berger..top end bullets, you sometimes get 1.5 MOA or worse!! Look at that 3.3 MOA group? I have not seen that since I bought some WOLF 5.56 ammo in the 90's for $1 a box, then shot it out of a $600 AR15 in a 10 MPH wind.
Notice I put these 77 Grain OTM's in Valkyrie and all of a sudden I am SUB MOA AGAIN? With almost any load I try? I just rolled the dice and tried 2 random loads and both were under MOA. So easy? I load up 70 VLD, I never made a load with it before, I just tossed a random load I guessed at...and its sub MOA using silly ball powder.
This is all from 50 Yards.
