Steel based hulls will do that on some of the " new " guns and older models even worse. AAHS AACF or Remington STS are Brass base only, not steel. Steel with Brass wash sucks. All Euro ammo for the most part and most other Federal or Remington products will use steel bases. They expand different and usually only work ok with some pumps or doubles that have ejectors. Hard on reload equipment dies, just over all cheaper metal that sucks for ammo in many guns not designed to handle the extra space needed for expansion of the Brass vs Steel.
What off the shelf ammo were you Shooting??? Federal tends to be loaded cheap but they offer lots of expensive lines. Winchesters Super-X is the same hull as AAHS, Brass based no matter 3/4 oz or 1 oz magnum loads. All the same AAHS hull. Remington has or had STS and Gun Club. Nitro Express or Express 28's are steel bases on some and older ones are Brass. Rio, Fio, and Euro all run Chedditte type hulls similar to Federal's paper or plastic base wad hull........( Straight walled hull ... room for everything + the dickens. )
Ejected the federal but wouldn’t the winchester
