i have shot both out of my marauder in .22 and i honestly had better groups with the boxed ones but not so much better that ill pay double again.and even though i shot ok with them they still have fliers in the box.
i think the only way to not get fliers with any of crosman pellets is to weigh them and inspect the skirts.pain in the %$# yes but i think its the only way with this brand ammo
HnN and predator polymags are the only brands of ammo ive found to not have fliers and you can see how good these pellets are made.
