It really depends on the accuracy of the rifle you're shooting, to firgure out how many reloads you should have on hand.
For milsurps, especially those with a lot of wear, it's not a bad idea to have a lot of loaded ammo on hand.
For newer, new in grease, sniper versions, etc. it's not a great practice to have hundreds or thousands of rounds pre loaded.
I fully understand the practice and idea behind having reliable loaded ammo in quantity on hand.
However, as you start shooting, the leade wear and the throat is extended by however much it's worn.
For average rifles, this bit of wear doesn't make much of a difference, but with very accurate firearms that bit of wear can bring on all kinds of group or POI issues as the wear increases.
The 22 Hornet is notorious for being "fussy" about little changes.
OP, you may notice your accuracy falling off as you use that ammo.
