I have a bit of a supply of Denver 43. But it is loose not in a box. Got it at Knob Creek years ago. Last I tried it the ammo was save the bullet, powder and brass due to duds and hang fires. It is a hassle to ship in my opinion especially in small quantities. So you might want to buy bulk. Now I am thinking it may have been Denver 42 Ammo. If your interested get back to me about a bulk sale or PU in Green Bay or Appleton, Wi. Regards, John.
