i use .030, or .060 vegi wads from john walters, 405 799 0376. they work well under the bullet for more reasons than i know.. for me it increases compression with out increasing powder amount.. i use on one of my loads two .060 with a gas check bullets without gas check and have no problems.. to develop a good load for your climate, gun, type of powder they can do the trick sometimes.. i would recomend trying them. i dont know about the .025 cards.. dave..
