Go with a .169" if you want shorter as that will put them at 2,820" at about .020" off the lands but I would try to shoot what you have now first.
Haven't put barrel on yet. Still shooting M12 LRP
Just getting as much information ad I can before I switch barrels.

Rob01 hows come you're not shooting 147 eldm?
Could they be just a little heavy for the creedmoor?

Thanks
