Received my 24" 264 LBC barrel after waiting for awhile. This is my 5th Grendel/264LBC barrel and I must say every barrel I have has a different throat length on them. The BHW is by far the shortest throat of all my barrels. I have a Base to Tip and a Base Ogive digital measuring set up to measure everything that I shoot. My BHW barrel is without a gas port as I build an AR similar to what the English are doing to shoot AR's. I use a side charging upper, free float forearm. It is a bench rifle. Has anyone done any bullet to lands measuring on their barrels?
