Objectively demonstrate how 1:11 will not stabilize any reliable hunting bullet fired from a .308 Win. Please also tell all the animals killed by 130-200+ gn bullets from same how not dead they are (including those in my freezer). Also, we should probably remove all the Palma and F-class records set with 1:11.25 - 1:12 (see Brad Sauve, 2004).
The argument that greater spin rate is "necessary" for the .308 has been repetitively disproven on this site and by any reputable reloading manual.
On the other hand, I may be misreading your statement and if so, please ignore all the above.
