I generally find people are pretty interested in them. Our range has few people who come to blast away. Most are competition shooters, F-class, center fire benchrest, 22LR guys, and a handful of guys who just hunt. The only negatives I get these days are when the benchrest guys are trying to shoot bughole groups and I fill the air with smoke so they can't see. I avoid shooting my long range BPTR rifles on still air days for that reason and then we all get along .
I've had plenty of non-competition guys shoot my rifles, but I've never ever had a serious competition shooter want to try my rifles. Not sure why. They are often impressed at the accuracy though. I once had a TR guy think that my shots were all over the place at 300 and he was concerned that I was maybe damaging some of the equipment in the pits. When he saw the group in the spotting scope he said it would have be a pretty decent TR score . He became much friendlier after that.
