That range sounds like...no, wait, *IS* an accident waiting to happen, thank the great Flying Spaghetti Monster that you escaped largely uninjured, and I think you made the right decision to find a different range, my local range has a single shooting hut with individual bays on the rifle range and on the handgun range, all shooters are pointing in the same direction, and nobody is in the lane of fire on a hot range
South Berwick Rod and Gun Association GPS coordinates are;
43.18737,-70.799117
Plug that into your GPS/smartphone/Google Maps, and see how a safe range is set up
from top to bottom;
doubles trap range
singles trap range
handgun range (up to 25 yards distance)
rifle range (200, 100, and 50 yard ranges)
It's an old satellite picture, the handgun range now has berms and backstops at 15, 20 and 25 yards, the pistol range in the image was the older "movable target holder" range with the single berm at 25 yards, and the rifle range shooting hut now extends all the way to the 50 yard range, the bright sand patches on the rifle range are the 200, 100 and 50 yard berms and backstops, the curved white blob is the side berm preventing stray bullet escapes to the right
the structure near the road is the clubhouse, and the archery range is directly across from it
notice, no shooting positions beyond the shooting huts?
