Mine is 2007, I also love the trigger
Look through the FAQ for installing or replacing barrels, look at the pictures of the latch surface, then look at yours.
My BC started popping open after around 50 rounds, even with lighter lead bullet loads.
I mostly shoot leaning on a bag so it never bothered me. In fact someone was watching me one day, he said "Wow, check it out, it even opens the action automatically after each shot"
.
I finally checked it out tonight (after reading the barrel section of the FAQ again).
I found a big burr on the barrel latch shelf. I removed it with a hard flat stone, now I have a good lockup! Wish I had seen this right away.
enjoy it, nothing like throwing 1/2 oz of lead 500 meters and hitting something!
