Well still havign dificulties finding the over powder and over shoot cards and the wads for shooting a 28 gage shootgun load. I did how ever find a 9/16 hole punch at dixie gun works for 29.95 it is decimal diamiter of .562 where the guage diamiter for a 28 gage is .550 No way to meshure my barel to decimal diamiter but it is a .54 caliber which I am told is a 28 gage as well. For shooting patched balls the gun smith sugested a 530 ball with a .10 patch which adds up to .540 Just thouhgt of this. That might explain why my .535 diamiter roundball and a .15 thousands of inch patch is such a tight fite gettign into the barel of my lyman .54 rifle. Alsmost nead a hammer to drive the load in but boy is it an acurate round when sittign ontop of 80 grains 3f goex. Basically I am asking is this. I know the cards and wad nead to be a tad over sized so it will fit snugly and stay snug. But is a .562 to snug for it do you think? If I do buy that 9/16 pounch any idea where i get teh sheets of fiber wad to make my wads? And what type of material do i use to make my cards? Is poster baord thik/rigid enouf? I got a month to figer this out as i will want to ahve from start of april till terky season opener to practice shooting it shootgun style for terky season. It will also give me 23 days to work on best laod for it.
