How do these heavy profile barrels compare to the lighter profile CHF barrels? I have been leaning towards a Criterion Core but these results are really promising from Geissele.
Had a chance to try some of the Hotter Loads with Geissele SPR and 22" Kreiger JP SCI-20.
Still haven't seen any pressure signs working all the way up to 24.7grs of Tac in 18" SPR and 24.1 in the 22" Kreiger.
22" Kreiger
Decent results with 23.7gr and 24.1gr
18" Geissele SPR.
24.5gr Tac
Shot this today with FF brass in the Geissele SPR. Creeping up on 200rds and the SPR barrel is starting to settle in, should get the TAC load locked in soon. Next will be IMR XBR and 77gr SMK.
23.8grs
