Tumbling range is much further than firing range for rifled rounds.
Most firing ranges today require lead traps installed behind the butts, precluding standard target practice rounds leaving the range, except in the cases of wildly inaccurate ricochets. Those traps are driven by environmental regs on lead.
It appears the range uses the lake as an additional safety buffer, but it might actually allow some far ranging rounds to ricochet off the water.
IMHO, the range should insure QC inspections of all ammo fired as a method to document they are safely operating their range. Besides, it also would help defend nuisance lawsuits by those who would make fraudulent claims against the firing range.
correction: Tumbling range is much further than max effective range for rifled rounds.
...”IMHO, the range should insure QC inspections of all ammo fired”...
You sure lost me there.
