Several. Rimfire ammo can be notoriously inconsistent. I've seen as much as 275fps extreme spread from the same box (Remington BTW). With match ammo, the 1st consistency aid is usually Eley priming, whcih is much more unform and consistent on ignition. Then powder controls and bullet uniformity.
There are even .22LR uniforming tools on the market for the serious shooter.

I used to weigh my .22 rounds before a match. Used the High and low weights for warm up and plinking, all in the middle weight rounds for the match.
The FWB rifles we use at ft Benning on the army rifle team are $5000 .22's, they make a diff like match .308 in a custom rifle.
Have you fired any and can tell a difference?
I have a .22 short that is picky and has problems. For about 1 in 10, the bolt hits too hard and slams the nub of a firing pin too far so that the case bursts along the rim. Gives me a nice little puff of air in the face.
I've been thinking about trying different ammo (since not every casing shows excessive force) before attempting to adjust or modify the firing pin or the distance the bolt travels.

Like everyone else is saying you pay for what you get. Every type of ammo will act very different with every gun.
