Nice group! If the accuracy holds up I would pretty much call load development done. Someone posted that they fixed collapsed shoulder brass by running them through a 30-06 sizing die first (I think they were 6.5 grendel) and then again through the regular die. Give it try and let us know if it works for the ARC as well. As for Imperial sizing wax, it's pretty hard to remove. In fact I'm running some .223 brass for a second time through the wet tumble process as the first time left some sticky residue. Good news is that it's likely a good thing to have in the inside neck to prevent neck weld if stored for a long time. Appreciate the write up, thanks!
