Had mine about three weeks. GREATEST rifle of all time. Mine is a CZ 527 Varmint. I cannot believe anyone that shoots does not have one. They have only been around about 10 years. They shoot, according to my wife, "cute little bullets." But, they leave the muzzle at 4000+ fps. I reload, they only take about a 1/3 or 1/2 of the powder of my 25-06 (which is not that big a cartridge either.) As most of you know, I am an idiot. Here is picture of my 16 through 20th shot. My first shot with the VMAX (Hornady) bullet. 99% rifle, 1% me!
