I got a case of Rem 6-1/2 primers for reloading 30 carbine. But I'll never load that much for 30 carbine. I'd like to use them for 40S&W in my Glock 23. Anyone try this. I'll start low and work up so thats not a problem. But the Rm 6-1/2 is a small rifle primer with a thinner case. I've heard that the Glock might not have enough 'umph' in the firing pin to ignite small rifle primers, but the 6-1/2 is a thin walled primer as rifle primers go. Anyone try this.
