I have a CZ 550 Premium grade in 30-06 that has developed a one shot flyer problem. The first shot will be 3-4 inches high, the rest of the 4 shots from the magazine will print a nice tight group. I tried firing the rifle single shot, suspecting that the magazine spring was a problem. Still does it. I am using Sierra handloads, 168 Gr. HPBT Match 2200, 4895 powder.
I have been a big believer in CZ guns, I have 8 of them. However, this rifle has been more of a problem child, the average factory load or my 150 grain handloads always had less than excellent accuracy, they shot fine for hunting, but not the tight groups I wanted. The Sierra Match 2200 have been getting me the tight groups, but with this first flyer problem.
The screws on the action and the scope are tight. The rifle is fired on average of 5-10 shots, allowed to cool, so heat does not seem to be it. The amount of ammo through it is believed to be around 1,200 rounds to date, not too bad for a centerfire in terms of wear. I used to have a Marlin Model 25 bolt action rifle in .22 RF that used to do that, one flyer in each 5 shot group, I sold off the Marlin as I suspected that it was because of it being cheap and poorly made.
Any suggestions?
Thanks.
