i just use the winchester original 209 primers. You have to realise that every company is going to throw out something cute to sucker us in. Like the lil silver 209 primer with the lil black center. woohoo its cool looking! These places have suckered me in before but now im sticking with the original stuff that works great still. Take the new powerbelts for example. Sure they have a new covering and a new base, Okay good, But the Originals work great for me and therefore i see no reason to change. Find what works best for you and stick with it. Ive been shooting off a box of 100 primers for going on 2 years and they still work great. Never had a misfire or delay. And what ever you do, Do not use the Sabor tooth bullets. They just want to you to think they are a powerbelt. I used them lastyear and 1st day of the hunt i fire at a deer and it looks around, runs off. Hmmmm thats weird the gun didnt kick.. Walk back down the trail. AHHHHH fudge! Yeah that cute lil cup they sit in, Doesnt hold the bullet and it fell out while i was walking up the trail. Good thing i had some extra powerbelts on me because i used it.
