Easily I'm afraid
. A recent batch of JSB Express I bought were terrible in three rifles I tested them with. At 25 yards
I was struggling to get sub 25mm 5 shot groups
In one rifle (S410) they were ok.
Returning to my remaining EE and favourite Exacts saw a return to tight groups with the other rifles.
I always try and keep at least one tin of proven pellets back to cross check against, that way you have hopefully removed one variable.
