Oups, working on our documentation center, I may say that I have never enough info !!!
We have more and more books about ammunitions but I try always to find a book more, that we not have.
I known also, by experience, that it is sometimes difficult to obtain the correct answer on our question. Time, mood, authority, afraid of reaction on the question,...
Don't be angry, it's human !
Happy christmas and peace to people of good will !
