Azar,

Thanks for that as that was where I've been running my pressure limits, 2 to 3K below MAP.
I'm relatively prudent about working up to max loads but I'll admit that I'm a fan of velocity and I'll generally try to wring the potential out of the cartridges I load for.
Sometimes I find that I have to back off a bit after I find pressure but more often I find acceptable accuracy up at the top.
Silly as it may be, and it is, I'll sacrifice 1/4 MOA for an extra 200fps. Mostly though, that has not been required.
