He said what ? Obviously shooter error . There is no other reason all rounds shouldn't pass through the same hole . Just about every other sporting rifle on the internet can shoot caliber sized groups , yours should too ! Actually a quarter inch from centers is probably more like 1/4 MOA . It could be the rifle , there's alot of junk out there on the market these days . Seriously , if you can improve the performance of your rifle , please document everything you did and PM me with your results , inquiring minds want to know !
