Also some primers are better tolerated than others. Several friends have K-80 which do not like Cheddite primers. One Browning gun I know pierces them with regularity. Different factory ammo will get you to different primers.
Yes, if you can get a few factory loaded rounds each of Winchester and Remington. Try those.
Winchester's are softer and the gun may not open easily after shooting.
Remington primers on the other hand are harder and may open easier after shooting.
I have a Fox double that likes Remingtons but not Winchesters.
