Mylar Wraps are placed inside the shotcup to protect the barrel from contact with steel pellets. Designed for use with steel sized #2 and up. Wraps are .003" thick and can be used with all gauges. Package of 100.
Dimensions: 2 3/8" x 1 5/8"
Notes: When used to line the shotshell before loading, the mylar wrap stays with the shot upon firing and gives the barrel added protection from scoring caused by steel shot.
