153.5 hybrid in Creedmoor, x47, or 260?

[6.5grendel]

Anyone shooting the new Berger 153.5 hybrids in a Creedmoor, x47, 260 rem, or similar sized cartridge? I have a 26" long throated 260 Rem and have been shooting the 142 SMKs. I am thinking of trying the 144 or 153.5 hybrids and can't find much load data on the 153.5's. What powders and speeds are you guys getting with them and have you had any luck running them? I was hoping to run H4350, H4831SC, or IMR4831 and just start by backing off my current charge weights by several grains and working up. Thanks for any advice.
