Me and some friends were out shooting and a buddy was shooting my model 11 .223 and noticed how cool my brass was right after firing. I had never noticed before. But compared to the AR's and pistols we were shooting my brass was extremely cool. I'm thinking it only changed a few degrees. I was wondering if anyone else has noticed this or knew why? Just cause its a bolt gun? I'm not worried about anything, just like learning and curious. They are hand loads. 24.0 gr Varget pushing a 69 SMK. Thanks!
