Bought a Bergara BMR 22LR carbon barrel. I love everything about this gun. Warmed up it is extremely accurate with most any ammo. Pic posted attached. HOWEVER, when a cold barrel straight out of the case it is the absolute worst shooting 22LR I have or even know of. If you shoot it and wait an hour or so it still does pretty darn good. But wait 24 hours and awful. I only post this so that if you want a hunting rifle this probably isn't it. And if you have issues my experience is that you are stuck with it. If you want to paper punch and are willing to warm it up first it is a tack driver. Sent back to Bergara and they sighted it in, set it aside, felt the barrel for warmth (carbon?) and shot some groups which passed their protocol. I asked if I could pay send it back to sit for 24 hours then test and they said no. Offered to send with my optics - no. Offered to pay the shipping back - no. Any other avenues to solve the issue - no. Very disappointed. See target attached. Read the labels on the target carefully. This was repeated over and over and over starting with different ammo, clean, dirty, cleaning the chamber with Bor-tek C4, etc. Has about 250-300 rounds through it. The groups keep getting better and better when warm as the barrel has seasoned. But cold, it is just plain awful for the first 3 shots. Anyone want to buy it? Disclaimer shoots terrible cold, shoots fantastic warm.
