some years ago when I first got a 2260 (same barrel, just longer) I was totally in aww as I had never experienced real accuracy in an air rifle. I had a silver streak for almost 50 years and a rws 45 for 20 years.
I crowned per instructions and set some targets up. the pellets were going in the same hole and I was sure it was some fluke or accident. I believe the cphp was designed for that barrel. they just work.
