Tracer rounds

[One1]

I’m interested in picking up some tracer rounds and I’ve been watching this video which has given me some questions. 
 

 

First, do you think something as small as a 22LR would be visible in overcast light with it being such a small round?

Second, with these cartridges already being dirty do you think this will cause even more nastiness in the bore?

Third, these are the most unreliable cartridges as it is, would tracers make them any more unreliable?

I stumbled across these, but have not been a crash test dummy.

I've shot the Piney Mountain .22 tracers.  They work very well.  Only trace for about 100 to 150 yards, but how far are you shooting .22 anyway?

Tracers do not cause fouling or unreliability.  

They are expensive for .22 ammo, but lots of fun.
