Larry;
Agreed; read this line from my last post "The pressure there will in fact be very sightly higher, though mostly insignificant". This is what I have been saying for ages. People though still keep saying I have barrels which are thin in the forward end, therefore I am going to shoot "Low Pressure" loads to protect them. They are simply like an ostrich with their heads stuck in the sand. True the difference is very slight, but whatever difference there is, it is in the opposite direction of their stated goal. Nuff said, you either have it by now or you'r one of the Ostriches.
