Brent - i had used mrp-2 and either 123 or 139 scenar. both hunting and competition. in my 6.5-284s. no more mrp 2. i went to mrp. several years ago i picked up 400 -130 grain norma. I had not tried them until a year ago or so, awesome. they were i think 2.5-3" flatter at 500 . than the other ones. geat groups too.
I'm working with a custom 6.5PRC with a 23.5" Proof barrel. So far it has been very difficult to establish an accuracy load for, generally shooting about moa. I've got some Berger 135 Classic Hunter bullets and noticed that you're getting 3,100 ft/sec with 135s. Would you be interested in sharing your load info?
