I usually do 5 shot groups.I usually do 10 shot groups. IMO that gives you more information than 3 or 5 shot groups.
That's why I always load at least 10rds of each powder weight when I'm testing new loads.
I sure hope that 8" group isn't at 100yds. I'm pretty sure rifled shotgun slugs with iron sights can do that.
This is something that we easily forget. Good aligned irons are pretty accurate. One of the 1000 yard matches at the National Championships allows "any sight". I set my rifle up with a good tapered base, a good scope, on good rings. It was an accurate rig.HOWEVER last range trip I just did 3 from my Yote rig w 1-4X at 100 yds.
It did an inch or just under. Which is what it did before I removed scope/mount.
Same ammo, same lot #.
This is true. My muzzle loader is set up for sabots. It is very accurate, AFTER the first shot after cleaning. I always foul with at least one shot before taking it to the field.Honestly, I would test for cleaning interval and clean vs fouled bore.
I want my first shot on critters to be known.
Some rifles could be picky.
Try reloading. At 100 yds, my Armalite AR 1:9 averages 1.5" with 21.8gr H335 and Sierra Game King 55gr pills.Yes, 16" barrel with 1:8 twist. Dang, I had hoped to stay with 55 grain since that seems to be much more available. You`re right though.
My hunting rifles get cold barrel loads and accuracy tests. Because of doubt I'll get more than one shot anyway.I usually do 5 shot groups.
Doubt I'd ever rip 10 shots at a non paper target.
Of course, seeing what a hot bbl does vs lesser temp is proly worth checking out.

That is exactly what Springfield Armory said they accuracy check with.I would suggest you buy a few boxes of these and see what it does.
