Re: 2950 with a 6.5 Creedmore?
I got 2910fps with RL-17, but although it didn't show typical pressure signs, it did fluctuate vastly, and shucked a couple primers.
I say you can do 2900+ with the CM, but at the expense of your brass... Not to mention the RL-17 didn't seem to be that consistent, although I'm going to retry it before I commit to that statement as I was having some funky neck tension problems at the time.
