dipper Posted September 30, 2012 Report Share Posted September 30, 2012 Been loading some heavy L/V loads with new cases useing frangible plastic top wad.Surfing the net on some reloading sites saw recommendations for card o/s wads 30 th thick cut some out of yellow card my thinking was to write data on wad so i could identify them. Loaded a few to try clays they seemed ok . on cleaning. barrels were not as clean as my usual cartridges. got me thinking with the thin card not much resistance holding the shot reducing the velocity a bit too much. Back to the drawing board.Dipper Quote Link to comment Share on other sites More sharing options...

snarepeg Posted October 1, 2012 Report Share Posted October 1, 2012 If you are useing heavy load powder(/i.e slow burning )for a light load you will get unburnt powder left, it needs pressure/wieght to burn cleaner a deeper roll/crimp will help but probably not as much. john Quote Link to comment Share on other sites More sharing options...
Mick Shaw Posted October 1, 2012 Report Share Posted October 1, 2012 Hi Dipper I have found that to get the right pressure with roll crimps the following cards worked best for me... 12 gauge- 1.7 mm thick. 20 gauge- 1.5 mm thick. 28 gauge- 1.2 mm thick. 410 gauge- 1.0 mm thick. Hope this helps. Mick. Quote Link to comment Share on other sites More sharing options...
