A few comments in the tracers and gas thread got me thinking.... One poster wrote about tracers needing a certain amount of time to light off. A few months ago I bought a bunch of old ('60s) Lake City 7.62 tracer because it seemed like a neat thing to have. Normally I wouldn't dare shoot it at the range in dry west Texas but a couple weeks ago it was pouring rain and I gave it a try. Shot it all at a 100 yard gong and was pretty disappointed, really couldn't see much of anything other than some smoking holes in the dirt berm. Does it take a certain amount of time for a tracer to be fully visible?
I'm also a bit curious about tracers leaving residue in the gas system of semi auto rifles. The 7.62 tracer I shot through the PTR-91 so no concern there but I also have a quantity of 5.56 that I would like to try in the Sig556. Would any additional cleaning of the gas system be required afterwords?
Since it's for personal amusement rather than any tactical consideration I load up the whole magazine full of tracer. I'm assuming that any residue in the barrel would be blasted out by the following round which would negate any cumulative effect but I really don't know. I have never been shy about heating up the semi autos, is there any additional consideration when shooting tracer?
