[QUOTE="mrultramag, post: 87246, member: 4467"] I'm on my 3rd reload with some of my cases. So far a-ok. I've notice with the Rum's that when you are getting too hot a load that the model 700 gives that signature ejector plunger mark on the brass head. This is also usually an indication that you have just ruined that piece of brass as the primer pocket has usually expanded more than I'm comfortable with. not so much that you can prime the case with your finger but you notice that it doesn't offer much resistance to the rcbs hand primer. I don't know how people feel about Rick Jamison but he had an article on reloading the 7 Rum a few years back. Seems he had some problems with the case neck area work hardening after 3-4 reloads and needing to anneal them to lengthen their servicable life further. PS- I size my brass just enough that it chambers well. I use rcbs fl sizing dies. [/QUOTE]
