I took some of the Georgia Arms "Canned Heat" in 45 GAP to the range today and ran it through one of my G39s. I found the ammunition to be very clean and accurate. It functioned 100%. I was using the 185gr FMJ - and it is rated at 875 fps. I found it to be a mild shooting load in the little G39 -- great target/plinking ammunition. I'll definitely be buying more of the Canned Heat in 45 GAP!
