Indoor shooting contributes to blast exposure more than outdoor. Blast exposure to the head is harmful and may be cumulative.
The larger the caliber, the closer the muzzle to the shooter’s head, the greater the exposure.
There is a time/rep component to hitting possibly harmful thresholds. More shots faster equals more possible damage.
Hear all the maybes? That’s because there is no real science-based standard. Uncle is working on it.
Muzzle devices that mitigate blast seem to help.
Work in progress.
I’ve been shooting 375 and 470 indoors. And 9, 45, 22, 223, 257, 30-06, 300
Thinking I oughta take the big stuff outside.
