I've got a number of comparators but not .277.
I was wondering how much rifling bearing area the new ablr has. Just trying to get a finger on how "sticky" this bullet might be.
Using some hillbilly measurements using two calipers I'm coming up with the actual caliber width of the shank being surprisingly short compared to how long the bullet is.
In other words subtracting the length of the boattail and the length of ogive to tip I'm actually coming up with the ablr being less shank than a 140 AccuBond.....and being real close to a conventional cup and core.
Can someone check this out via a. 277 comparator?
