Some good points.
1 shoot far left.
2 shoot as far away to avoid vibration from sustained fire
3 avoid public ranges filled with black gun / rubber knifers
4 wear plugs and muffs to give extra protection from noise and BS
You guys missed the most important one, be friendly. One day at the local range I had a hard time getting off the 10 test rounds I came with due to non stop fire from them;) So at the end of my shooting I was talking with an elderly gentleman / range officer who is a friend of mine. (he too loves black guns) So while a few of the black gun owners were listening I told Jack we should hold a BLACK GUN SHOOT. Boy did that draw some attention. One asked what would you shoot and how is it run ( yeah he took the bait, now I got to set the hook) I tokd him I would shoot a 338 Lapua with 300 grain smk's at 2950 fps. He said well thats not fair thats not a black gun (assault rifle) I told him yeah it gets better, the rules for the shoot are we hang all the black guns from the target backers and I get to shoot each one. I guess i forgot about being friendly that day
