How many reloads are you guys getting with Remington brand brass? I've got a 338 RUM and yesterday when I was priming the cases I noticed the pockets were very loose. And by loose I mean I barely had any resistance putting the primers in using an RCBS hand primer. I know it's time for new brass when this happens but I've only gotten 4 loadings out of them. The other interesting thing is that I havent needed to trim them yet so I figured they were still good to go. I'm alittle confused by this. Any info would be great.
