If it's not readily recognized , small caliber,lots of wood, blue steel, and single action or double barreled, it can look cheap or repulsive to this crowd.
Great, less competition for the stuff I happen to like.
I remember way back (in the olden days my kids remind me) when I went deer hunting and I was about 19 or 20. I was invited by a friend, and I didn't have much money and certainly not a fine hunting rifle, so I took what I had, an M1 Garand. Well first evening after arrival I was pretty well derided about my choice in rifles, and everyone pretty much doubted I could take a deer at the west Texas distances they shot at.
Long story short version, only one deer was taken the next day which was opening day, a nice 8 point buck at about 180 yards, yep, my Garand. So don't worry about what others think. As long as you're comfortable with them, have fun. Life is too short to worry about inconsequential things.
Oh one other thought, do you think those other guys at the range can outshoot you with your "junk" guns? Nothing better than to show them up. That's the best kind of satisfaction.
