This is a real head scratcher.
Buddy has one and cannot get groups under an inch and a quarter at a hundred yards.
So he was shooting beside me today and finally I said: Mine is in the back of the truck, give it a try w/your ammo. He took a shot and I said it is sighted in about an inch high. He said it is right there. I told him the first shot usually goes a bit wild, then it is usually good the rest of the day. Then he took four more and those four cut one hole less than a quarter inch about a half inch left of the "fouling shot."
He tried my Calhoon Single Shot adapter in his rifle, just to see if the bullet was being bent coming out of the magazine. No bueno. It shot as bad with the SS adapter.
The barrel is free all the way down to the recoil lug. We took it out of the stock and I have never had such a problem getting a 527 back in the stock. I have three and have owned a five and this is a new one on me. You just cannot get it together unless you shove the magazine in.
I am saying: Send it to CZ, but they might say it is w/in spec though. It is shooting ~ an inch +-. His rifle has a nice looking stock too, and he might end up with a stock that looks like a fence post (like mine) when he gets it back.
Any thoughts? Given it is a 250 yard chuck, prairie dog and grey digger gun... it is capable on all but the diggers. But I would be pretty let down if any of the three 527s I am currently shooting were not capable of "threading the needle" and slipping a 20 grainer between two basalt boulders an inch apart off a harris bipod to take out a chuck that wouldn't give me more to shoot at.
His rifle had a 24x Leupold on it today and mine a Leupold 6.5-20. I guess it wasn't doing any better w/a 4-16 he had on it before this morning.
