You have a battle rifle not a target rifle. Those groups fall inside the accuracy requirements for a Enfield battle rifle. These rifles can be tweaked a little but this will change a collector Milsurp to a range rifle. I have both with the amount of work to be done for a little gain leave it as is and use it as a battle rifle and compete in service matches with similar rifles. If you want a range rifle buy one already to go. Then work on finding a reload that works in that rifle. The battle rifle will put down any thing at normal hunting distances. Enjoy what you have.
