Good info larry. I will concede paragraph 1.

And totally agree with paragraph 3.

However, I am also an Engineer and as far as I know "Obturation" in the sense of firearms usage means the same thing as "expand" with reference to a soft projectile. I agree the 500 gr was to fill the bore from inerita, so you are saying the 405 was intended too also? I never talked with Spence, as he died before I was reloading for the Trapdoor, so I will have to concede to your knowledge here also. If there were issues with the 405 filling the bore, I dont remember he stating such. Figured his Son would have added something in the 3rd edition?
