I was shooting at Gander Mountain the other night and there was a guy shooting CX Maxima 250s with 75 grain tips trough a 70# 82nd Airborne with a 29" DL. I don't remember how much he said they weighed, but they are clearly less than 5 gpp. Wouldn't that void the warranty on the limbs? On to under-spining. I know for a fact that he should be shooting 350s at those specs. Couldn't he possibly snap an arrow into my arm if I am on the line with him? I asked him why he is doing this and he said, "to get to 350 fps." This isn't a young guy, he is at least 40 and a total jerk.

He said that as long as he cuts the arrows shorter (28"), they are not under-spined. He also said that as long as you have a string stop, the 5 gpp rule does not apply.

I tried to explain to him that my arrows carry more momentum than his because they weigh more, but he wasn't having any of it. What do you guys make of this?
