I prefer to shim the bow,so as to keep lotsa case head engaged to boltface(PF's and CRF's both),but it appears that you've got it whipped.
Shot THE fhuqk outta my 22BR today and it's trying to swoon me like my 6BR's,which is BIG medicine.
Hint.
Your COAL looks purty short and if thangs get hasty,it shore is nice to be driving AICS DBM's.
