Here is my first round of handloads for the Scar 20 (topped off with a NF 4-32, NF mount). I am using primed Lake city brass, IMR 4064, Hornady 178 BTHP. I have attached a photo of the results. There was an interesting group at 41.5 grains. Now I am no expert shooter, shooting from a bench is a little awkward for me (there is no option to go prone, have to shoot from the bench)
I am going to load up some more rounds for the 41.5 and some at 41.4 and 41.6 and see what happens.
