Thanks Shadow.

OK, so I ran another 195 rounds through the Gen 2 in stock setup.  150 were 180 Grain AE, 20 were Corbon 165 JHP & 25 were Underwood 180 TMJ.  With the exception of the Underwood, function and accuracy was superb.  The Underwood still had FTF & RTB issues.  I am convinced I have an out of spec lot of Underwood 180 TMJ.  I have 50 left and will most likely break them down for components .......

Thanks for all the helpful suggestions.   I really think my Gen 2 runs reliably with the stock setup, just not with the Underwood 180 TMJ.
