Try shooting 10 shot groups.
When I worked at Federal we shot 4, 10 shot groups and then take the average.
10 shot groups are just too exhausting. No one wats to do that crap anymore. By the way, the op found out his rifle bedding was the culprit. A tweaked/torqued receiver or one with poor bedding can always be an issue. Hence the reason i always say proper bedding is the foundation for a consistently accurate rifle. Others have been saying the same schidt for a hell of a long time. And yet, you still have guys with improperly bedded, or not bedded at all rifles, and expecting them to drive tacks day in year after year. Let me tell you folks, you are living in a fantasy world. A pipe dream, if you will..
