I was assigned the 100 yard range.
Learned a couple of things today through observation of others on the range. When buying a used rifle look at the stamping on the barrel to confirm the cartridge the firearm is chambered in. Do not trust the seller even if they are a reputable LGS.
A LGS might sell a .300 Weatherby (WBY) as a .300 WSM. A .300 WSM will not chamber in a .300 Weatherby and I assume the reverse is true. The .300 WSM is too fat for the .300 Weatherby and the .300 Weatherby would be too long for the .300 WSM.
If someone shows up and there are screws falling off there firearm right out of the case and the screw on covers inadvertently fly off their optic then they may have other issues such as malfunctions, bad ammo.. leading up to a stuck case and an out of battery discharge on a pimped out AK.
Great time on range duty. Every shooter acted in a safe manner. No firearm was pointed in a direction other than down range (that I saw or heard about). When the range was cold shooters respected the safe line and did not approach benches nor handle firearms while others were down range. Everyone heard and understood the range commands. I can't wait to get out and actually shoot on Wednesday. Also looking forward to my next RSO day in October. Today was not a very busy day. I assume that, getting closer to deer hunting opener, it will be busier next time.
