So another question is if the compounded throat for the Grendel measures different CBTO from every manufacture, Liberty, Lilja, AA, Brownells and so on, and the Ogive is all over the place, this is making factory ammo have to jump to the lands. I have different CBTO measurements on every one of these barrels. The Lilja has the longest CBOT out of all of them (SST's 1.768). The AA Barrel I have and Liberty are only .036 difference on the SST123's (AA 1.694 & Liberty 1.668).
