shots in group for testing

[m77mkii]

Just wondering what is accepted as guideline for the grendel in accuracy testing? 3,4,5 shots for a group?

5-shot groups

[m77mkii]

so if 5 shot group is tight then you know it is a good load?

Up to you as to what metric you use to compare variables - I use four. The manufacturer industry standard is three (cheaper, and the groups are 'smaller'). Some of the F Class shooters at my old club used 10. I'm thinking there is an argument for shooting more rounds/group the more precise you gun is but then again, you can just shoot more groups and average them all. Or be more precise in your measuring.

As long as you compare apples with apples, and on that point make clear the number of rounds/group when sharing with others.

In my own view, if one is interested in hunting, where each shot is critical, then the groups need to to be repeated over several range sessions to determine what variablility in size and center can creep in from temperature, light, and wind. This applies independent of range.

When I'm working up loads I use 3 shot groups, just because I got sick of what felt like wasting bullets. Though so far I've only used groups to gauge performance at 100 yards, 200 yards to 1000 yards I'm just trying to hit the target as close to a specific spot as possible.

I used to compete in archery, and always thought if someone shot just one arrow every day at random distances 10-50 yards, he or she would be a very good shot.
Kind of reminds me of the above post.

I use 3 shot and call every shot [ if i feel i was a little off one way or what] I am a hunter so I sight my rifles only on first shot cold tube, when i get down to two loads to stay with i shoot 5 shot with a warm tube.

5-shots and I always record my cold bore shot. For load development I use 5-shot and because I'm just not that good I dismiss my usual flier when evaluating best load.

I was also told that when I was very young.

I believe the same is true with rifles and pistols.
