DF,
How many bullets per group?
The reason I ask is on the first near-windless day I shot my CZ 452 back in 2003, the initial group at 100 yards was with the 17-grain CCI/Speer TNT load, and measured .24"--but was only 3 shots.
That impressed me, but the next group was shot with the 17 V-Max Hornady load, and the first 4 went into exactly half an inch, with the 5th shot a "flier" to make the final group 3/4".
Haven't shot another paper group with the 17 TNT load since then, though have killed quite a few varmints with it. I have far more faith in 5-shot groups as a real measure of a rifle's accuracy than 3-shot anymore, but also know benchrest shooters use hollow-point bullets instead of plastic-tips!
