HEVI-SHOT THROUGH TWIST & DAMASCUS BARRELS

[Dean Romig]

The problem in tightly choked guns is that this hard shot will not easily compress as it tries to get through the choke constriction and could (reportedly) cause ring bulges at the chokes. This was always the fear with steel and tight chokes.... shot cups or not.

[J. A. EARLY]

All guns are full and full. The big shot (bb, t, bbb, etc.) will bridge and bulge is a concern, but I guess my question is number 4s in Hevi-shot should not bridge but be compressed by the choke, and contained in a shot cup, should not score the barrels in the theory developed by my little brain.

That's where the doubt comes from.
