mikeh416Rigby; I agree with the rest of the replys. One and a quarter inch groups are good enough. Some people measure group by using center to center of the bullet holes, this is the accepted method in competition shooting. I measure my hunting rifle loads by just laying a circle template over the group and with 4 or 5 shot groups,just call as it fits. With a good shooting rifle and good ammuntions, just think about a 4x or 6x scope and a four inch black square target at 100 yards. Is every shot exactly centered when you break the trigger? If it's not, there is sighting error in you group results. The point is, if every shot you fire lands within three quarter of an inch when you broke the trigger, I think it's good enough. Load up a bunch of cartridges, shoot the hell out of your rifle, and take a really good buffalo with it. ERIC
