Files don't aspook me.(grin)
The Whizzum is a vastly superior chambering,but might not make the cut in the long term...being the 77/17 is the only Factory Rifle worth a fhuqk,chambered same. Ruger REALLY needs to chamber same in a S/S RAR.
I've multiples in each chambering,including both boltguns(obviously) and AR's.
LOVE 'em all.
