Good pictures as usual, Ed.

I am at a loss to understand why anyone would restrict & reduce the power of a gun by shootng an undersized projectile. Now, shooting sabots from a 120mm cannon, I see that and it certainly has merit. To reduce a wonderful .73 cal. rifle to a .50 or .54, well, I just don't understand the logic - unless it's just an execise in testing 'something' - that I understand.
