Hey guys I have a couple of quick questions regarding the 6.5x284. A friend of mine wants me to work up a load for him for his new cooper model 22. He has an ample supply of h4350 and h4831sc. All he has for primers is the cci 200. Im not seeing a lot of loads listed for this primer and that's all he can get his hands on. Will these work decent enough to bother with? And how hard is this caliber on brass? He bought the standard redding full length die instead of the bushing die so that will probably add to shorter brass life from over working the case.
