I’ve definitely considered the 129 Interlock and will pick up a box and work up a load to try. At the ranges I shoot at BC has never meant anything in my bullet choices. Actually, I did some searching and stores up some .243 and .284 Interlock round nose bullets to hunt with.

JCMCUBIC, what powder idi you use with the ABLRs?

Thanks for the replies. I’m really looking forward to completing and hunting with this rifle. I wanted to build a 6PPC years ago as a hunting rifle but there were no actions that fed them reliably until Sako, and those were expensive and difficult to find. The Grendel will be the PPC I always wanted. I built a 6x45 on a Sako Vixen action that scratched the small 6mm itch.
