Just found the big bore section a few days ago. Don’t know how I missed it! Anyway, here’s my 450 build. It sports an 18” BCA barrel, Kaw Valley linear comp, Aero upper, Burris Fullfield II 3-9x40 scope with PEPR mount. Lower is a PSA with Rock River NM varmint trigger, and EFX stock. Very good shooter giving 1” groups with factory Hornady 250 FTX.
