Hello, I just received a custom rifle I had ordered many moons ago. It's a defiance tactical in .308 with an 18" carbon bartlein barrel. It's all housed in an XLR element 4.0 Mg. It is intended to be my <=500y hunting / modern scout rifle (CGS Helios DT).
To zero the scope (Leupold 3-18x44 FFP) I decided to shoot some cheaper PMC X Tac 7.62 147gr. I really struggled to do any better then 2.5-3 moa over the course of 50 rounds. Velocity was actually fairly consistent at 2676 fps with a 12.4 SD, but I could not put together good groups.
It's my first carbon barrel. I tried to shoot 5 round groups and give it rest in between but maybe I got it too hot?
It's also my first lightweight chassis rifle and I'm used to being pretty light on the gun when I shoot. Should I potentially be pushing the rifle harder into my shoulder pocket?
It was a little disappointing, tbh. Usually I'm more like a 1-1.5moa shooter with the occasional sub-moa. I have some M118LR that shoots great out of my scar 20s and some Federal Berger Hunter Hybrid 168gr that I will try next, but I wanted to see if anyone had any feedback before I went back out.
Thank you
