Shot the ACR today with the 77 SMK's and the 75 HPBT's over Varget.
I wasn't shooting off a nice bench, and wasn't shooting paper targets, but I could tell that these
rounds were VERY accurate, and my ACR liked them. I was basically running the ladder loads
to see if I was getting pressure signs at 24.5 grn of Varget, and seeing if they'd stabilize out to 250
yards. They DID stabilize (damn accurate, and poi was almost dead on from what I could tell), and
never saw pressure signs at 24.5 grn. I thought 24 grn and 24.5 grn seemed to be about the same
from my rough results.
I was shooting at a 8" steel swinging target, 250 yards out. I was using a collapsable Coleman lawn
chair as my rest, while sitting on the side of a hill, on the dirt and using a 4X Accupoint scope. Not exactly
"ideal" conditions, but I was shooting a round every 1.5 seconds (barrel was HOT) and ringing the steel
on 90% of the shots. The ones I missed, was b/c I yanked the trigger... not the rifle.
I'd like to add that I was also shooting suppressed, and the rifle functioned 100% with all of my handloads
today (except the starting load of 23.5 grains of H335 on some 55 grn Blitzkings I was also working up).
My spotter (15 year old nephew said the 77's and 75's were VERY impressive when hitting the targets).
Very happy with the performance of the ACR today, as you can tell.
