Howdy. I just signed up but i have been reading for a while.today i did a bunch of chrno work with a 300 wsm and because of this thread i shot 2 pieces of brass to see how long they would last.one was Rem and one was winchester well i wore out before they did i quit at 20 times.the load was:190 gr match king bullet with cci 200 primer and 66.0 grs. of RL-17.the brass was fired before i started about 3 or 4 times oh the load shot 3019 fps.Good Luck
