Quoted: Did you mean 1X14 instead of 1X12 Dave?

Both, Tweak...
1:12 less so than 1:14, but both were still too slow... And he wants a 16" barrel, which will make it even worse...
.222 Remmington bolt-actions had these twist rates, and with no experience in making a shorter barreled (20" hunting rifle??? Most are 24 or 26" bbl) weapon in a slightly larger caliber, they just copied the twist rate...
Finally, twist rate has nothing to do with wounding, this is a myth...
All twist rate has to do with is weather or not you can hit the broad side of a barn... Too little twist with too heavy a bullet -> keyholing and horrible groups...
Proper twist -> accurate group size, and the bullet fragments (does NOT tumble) in flesh or similar mediums....
And as for fast twist rates, 1:7 is perfect for the new, heavy/long .223 rounds such as the Mk262 (77 gr Sierra)... Given the poor performance of M855 (M193 would be worse if it were still in use) out of the 'chosen' 14.5" barrels, the fast twist is a GOOD thing...
