I've only had one rifle that shot better with factory ammo over any handloads....a .225 Winchester in 1965.....

1 1/8" groups aren't bad at all.....but you should be able to improve on it....if it's worth it to you.

You didn't say what cartridge but if it's a .30-06 you probably can add 100-200 FPS and retain the accuracy by handloading.....and at less cost than factory stuff!
