Some 10/22's will throw a 1st round flier when bolt feeds first round from magazine but not on subsequent shots.
Some serious 10/22 shooters at my club use that first round as a sighter only..then shoot for group.
Probably something definitive at rimfirecentral.com....may be related to having or not having a pinned firing pin.
As for me fliers are always equipment-related and I'm sticking to that story.
