What can i get by with for a primer in this case. Cant find fed mag or any magnums for that matter.

I had the best results with a Rem. 9 1/2 Mag primer. It was enough to light off 108.5 grs. 24N41 with never so much as a hiccup. I tried every mag primer I could get my hands on & the Rem. worked the best.
