I went with a 22" Benchmark which has their own contour, but ultimately was aiming for a 22" Kukri Contour. Goal was to get a balanced rig that wasn't overly heavy.
The extra 2" of steel up front does help a good balance.
Downside of the 2" of extra length is my velocity is a bit slower, and Center-X ammo shoots like 1085fps in a 18-20" and it shoots down around 1055-1060 in a 22". Eley ammo though is a bit hotter and out of a 22" will shoot around 1090/1100 which is good. Curious if Lapua makes hotter ammo, maybe a 29xx lot.
Ace/Bartlein are more or less the same. There is no price difference between Ace or Bartlein.
