I found a shotgun primer that will ignite rifle powders, like RL15-19, IMR 4064,4198, etc. With regular shotgun primers I had to use Blue Dot starter. But not with these.....They are the industrial shotgun primers used in the 8ga kiln gun cases. I use these cases with basecup reduced in my 8 gauges. When I set up first 8ga I fired the primers only to test firing function(cases came with primer), then I put regular 209 primers in to test loads, with 4759 powder. Found box of WIN paper case kiln 3oz loads and took one apart and noticed it had 94gr of some ball powder. I wondered what powder is and how a regular shotgun primer could ignite that, based on our need for starter powder using regular rifle powders. So I fired that industrial primer and flame and sparks came out of 8ga NEF barrel 2-3 feet. Put a regular primer in same case and flame just a few inches. So I took REM kiln case with original REM industrial primer and 2-3 feet of flame,and put regular primer in and just few inches of flame. If anyone got info on th powder used and how to get these primers, let us know. I took some out of 8ga and put in 12ga plastic. Using these hairy industrial primers today fired 180gr of RL-15, in 12GA FH NEF, in 3.5" plastic cases with 437gr Brenekke KO slug. Got perfect ignition, no starter. 140gr with 600gr dixie, perfect ignition. Also I have the 12ga Encore that we tested loads in, on Gunbroker, in shotgun singleshot section.Ed
