You can order your completed fingerprint cards from silencer shop for $15 since you already used their kiosk. Some think it's expensive, I personally think it's convenient.
You asked a long time ago but I'm shooting the 300 prc with factory Hornady 212 ELD-X.... I'm happy with it/ them... they shoot better than I do.
Has anyone installed an area 419 ARCA rail on theirs?
