Root,
cant say you are wrong, lol, just going with how the two diff types work
for me. yea, same ammo, 36 grain, same velocity, h.p. copper washed,
but cant get the 750 stuff to shoot right, maybe the 745 stuff is older stock,
i dunno, but sure makes a lot of diff in my guns, night n day, the 750 ammo
was all over the place with all my guns,
