Took my Knight Super DISC 45 to the range today. 25°f. 80gr Volume bh209, Oxyoke .45 felt wad, 425gr Buffalo Bore bullet .451. Lehigh bp shimmed for 209A, clean and clear, Fed 209A primers. Poured my loads into a BH tube an hour before I left, could NOT get it to fire. 3 different loads, 12 primers. Nothing except a pop from the primer. Then i had to reseat the bullet. I tried 3 loads that I kept in my pocket to keep warm. First time ive had that happen that was not from something i did. Even had the RO check and confirm.
