I have load data for the 7/8 oz lee key drive slug to use active 2 3/4 inch hulls (I have them) but the data asks for an ACTIVE TG-30 Wad with a .135 filler. (don't have them and can't find them). I am a new smooth-bore reloader, but committed. I have reloaded pistol and rifle for 25+ years, so I understand the need for care and caution. Please advise if you have a proven safe substitute. (I am leary of the pressure risks that I read about with shotgun reloading so, until I learn more about what's what with shotshells, I want to stay safe). I am new to this forum, but have been reading the posts for about a month now. I will have more than a few questions. Thanks in advance. rhouser
