In the present case, both Hodgdon and Alexander Arms load data recommends a COL of 2.200" for the 90 gr TNT in the Grendel.
Who made the handbook and under what authority? Did they check with SAAMI specifications to come up with what is ok? Just wondering who has authority over anything. It sounds like nothing but opinions is driving the trend.
I think this trend of a possible chamber issue has gone off the tracks and down the tube.....
