The best 209 primers I have found to date,are the Cheddites. I've tried about every brand of 209(including the new 777 primers). The Chedittes seal the best,and are moisture proof. I shoot trap,and allot of shooters are using them,plus if you live around a gun club you can pick up a 1000 for around 20-22 dollars! They also seemed to produce the least crud ring in my prohunter.
