Chuck --

I understand your argument with respect to the point of impact for the upper barrel vs. the lower barrel. But, in point of fact the upper barrel does shoot high. Roger (see Roger's reply) and I undertook extensive testing. We considered barrel heating. We exchanged chokes between barrels. We both shot the gun. All these experiments lead to the same conclusion. There is a substantial divergence in the point of impact for the barrels.

Best Regards,
