I use cutters of various types, and when you don't overdo it they work fine.
Also used a cutter on a PILE of .17 Hornet brass when Hornady first came out with the round. For some reason quite a bit of the factory ammo had very shallow primer pockets, loaded with very "shallow" primers. (Where they got the primers I don't know.) Set up a small-primer uniforming tool in a drill motor, and deepened something 250-300 primer pockets so I could use "normal" SR primers. Am still using that brass today, no problems.
My 10 bucks says you had your dies set so the decapper was too low and the collet for the pin was pushing down from the inside and shortening the pockets
Ammo companies don’t make faulty cases then primers to match
