While at the range today I experienced something that never happened to me before. I had 2 rounds of .30/06 fail to fire. Both loaded from same box of Rem. 9 1/2 primers. I tried firing them twice and all I got was a deeper dent. I haveused Rem primers for more than 45 years and have loaded a few hundred rounds from this box of 1000. Primers have been kept dry.
