Shot a bird yesterday with the 3 1 / 2 1200 fps 5's. Had 2 of the magnums in the magazine, when I unloaded one the shells had the plastic disc completely gone in the end exposing the shot enclosed in resin. The other one the disc was partially broken and when I flipped with my fingernail it popped loose. Im assuming this happened under the recoil of the shot. Never heard of this before.Been shooting Long beards since they came out. Gunna call Winchester and see what they say.
