I am very fortunate that I still have primers of all sizes, but I am be conservative with the primers. I bought a 43c, 617-6, 63 and I have a ruger bearcat because I have a bunch of 22s and I have been able to buy 22s. All so me and family can shoot for a long while.I only have one 58 and it's all I need . It gets regular use . Primers ? I haven't seen any for sale for over a year and half . With ammo becoming more plentiful it would seem primers would be coming more available . I was in a small family owner gun store this past weekend and he had a pretty good selection of powder , but no primers . regards Paul
