[QUOTE="TonyRumore, post: 2973778, member: 2222"] The parent case is a 220 Swift with a re-machined rim-groove to 6.8 SPC. Runs in 6.5 Grendel mags. Shoots 85gr bullets at 3100fps. 90gr Accubond at 3025fps. 18" barrel. No pressure data, so take that for what its worth. I have one with a 1:7 twist and one at 1:10. I like the 1:10 better with 85-90gr bullets. If you want to shoot heavies, I would stick with the ARC. Tony Rumore Tromix [/QUOTE]
