I was going to just get a 12-inch .177 barrel for my AirForce guns but decided to get my LAST PCP today, No really. I don't like to spend a lot on one gun, and I am paranoid of them leaking or breaking so I ended up getting one more AirForce gun. This time it is a .177 TalonSS. I now have all of the 12-inch barrels, .177, .20, .22, and .25. and enough platforms that I will not have to be constantly swapping barrels. The .25 has always been my favorite because I can load them easily and see the holes in the target easily but with the cost of ammo as well as sometimes being hard to find. I decided to start shooting all of the different calibers and I am really enjoying the .20 once again. That caliber has just been crazy accurate out of every gun I have ever shot it out of.
