I am really at a loss to explain your problem... I have never had that type of problem with T7 and I gotta tell ya - I do not take ay special cares with it all. It is stored on the upper shelf of a cabinet in the gun room. I open it as I am shooting at the rock pit and half the time I forget to close the spout - so it is exposed to the atmosphere most of the time. I just finished my last bottle of 2005 T7-2f and just opened a bottle that I bought 01/06 from a Wal-mart buy out.
I have never seen clumping in T7 unless it was compressed.
So as you can see - I am know help...
