I hope you got to shoot some of those tracers into the ground. It's interesting to see how much they get deflected and bounce.
While tracer rounds are HOT, most of what you see in movies, when a tracer round hits a vehicle gas tank and explodes the entire vehicle is purely "Hollywood".
I had some 7.62x51 tracer rounds, and during a desert shoot, a buddy of mine wanted to see some "pyrotechnics". He had a full can of Coleman white gas, which is VERY flammible, and he set it up in a cleared, sandy area. I told my buddy that NOTHING was going to happen, other than putting some holes through the can, causing the white gas to spill out, even with the tracer rounds. He didn't believe me.
I backed off to 100 yards from that can and fired 3 rounds. The can didn't appear to have moved, and my buddy announced, "I think that you missed!"
I told him that I had hit it with all 3 tracer rounds. Again, he didn't believe me!
We walked out to the can, and....sure enough, there were 6 holes in that can (3 entry, 3 exit)!
By the time we got out there, the white gas had emptied to the level of the lowest hole. "Maybe that white gas isn't as flammible as I thought it would be", he said, just before he flipped a lighted cigarette onto the soaked sand. WHOOSH!
I sure wish he hadn't done that with me standing that close!
The reason why the white gas hadn't ignited from the tracer rounds? The gas wasn't mixed with air, and the rounds had gone through the liquid! Had that same can been, say, only 1/4th full, I think that it would have ignited if the rounds had gone through the FUMES!
