Sure you can!
It being a free country and all.
I'm just F'in with you.
It's actually a good question.
Rifle's are loud. (outdoor use mostly)
They deal with longer Ranges. (take up more space at ranges)
The biggest reason I think is cost too.
I was thinking about this the other day as I went by the range I will be joining soon.
They have a 1000 yard range, and I thought,
"this 1000 yard range is more then just skill, its money!"
Think about it, 1000 yards, if your up agaist people that have rifles that shoot 1/4 and 1/8 MOA, and your rifle is 1 moa, how are you going to compair with them? At 100 yards or lets say 200 yards, you could compair, but at 1000, no way!!
Also if you shoot 600-1000 yard ranges, the guy with handloads is going to kick almost anyones ass that has factory loads.
So as you can see, rifles in competition is more a niche area.
This is of course, my opinion, not a fact by any means, but hey, opinions is what your looking for right?
BTW, what does JC stand for?
