Re: shooting tracers
Roger that. A 62gr NATO tracer is a very long projectile, since it doesn't have the same density as lead.
They are the reason behind 1/7 twist as stated above, which is really for some of the 80gr and longer VLD-type pills with long bearing surfaces.
If you live anywhere out West, it's best to avoid shooting them out in dry conditions. Utah had at least 5 large brush fires started by shooters this year, resulting in loss of people's homes, evacuations of certain neighborhoods, and $$$$ damage.
Almost every belt-fed weapon range session in the military during dry months resulted in range fires, some of which included loss of life by foreign nationals who tried to fight one particular fire in the hills/mountains of Korea.
