I have a 27 Nosler, but it's based on the longer 26/28 Nosler so has a bit more powder capacity than Noslers 27N.
In load development with the 170gr Berger Elite Hunters while laddering up looking for max load I've seen 3,300 fps on the chrony.
Mr Songhurst created this 27N well before Nosler introduced it into their line up.
