I bought 4 boxes at my local Cabelas & none of those had the red around the primer, but i picked up a box at my local gun shop and all 50 primers had the red around them. Can someone explain to me what the purpose of the red stuff is for(I think i have an idea lol)? All 5 boxes are Q4369 if that matters, is this decent ammo? Thanks. Chris Wanna kill these ads?
