I collect and shoot military rifles and 300-400 yds with irons is easily doable if you know how to shoot and practice at it and I mean really practice. Learn how to use your sling correctly and shoot in various positions, prone, sitting, kneeling. I see guys every year that go to the range to get a few rounds in before the season starts and they’ve got their rifles in a sled on a bench. It’s not going to happen if that is your style of shooting/practicing.
