So far it has been Winchester Super X, Wolf Match and some CCI something or other. All ammo is stored in the house year round. I can remove the round that failed to fire, and it will fire in my 10/22.

My bone stock 10/22 with a cheap Simmons 6-18x50 out of the box. Did nothing but tighten up the action screws.

Upper 3 shots were winchester super x
3 shots under that were the same ammo but 4 clicks down on the scope
next 4 were federals with 6 clicks left on the scope
Done at 50 yds.
