22 NoslerReview by mturner / (Posted on 7/22/2018)There are plenty of AR bolts for the 6.8SPC (rimless 30-30) case head. Rebating the rim only weakens the case head, which in turn limits performance. The 22 Nosler holds more powder than the Valkyrie. It would have a greatest potential to be the performance king in an AR platform. Rebated rims are not well accepted in the AR community. Just ask them if they want a rebated rim or not. Most would prefer to use the bigger bolt face.
