5x PA Microprism with the vertical spacer (no offset) was 9.5oz on my scale.
The AAC ammo has impressed me. I use the 77g OTM in competition to 500 out of my Geissele with good results.My Shaw portless is doing alright with AAC 77 TMK. 1.5” is about average for 5 shots. Some of that is me getting used to the light weight and trigger. I did have one group about an inch not counting a shot I called as me.
Hoping as I get used to the rifle it can do a little better or I might need to load for it.
I did go 3 for 3 on a 300 yard gong pretty easily.
