Maybe he means that the .22 bullet will strike the wipes.
I've had good luck with a .22 conversion that I've used on my rifle. It's a Ciener drop-in bolt replacement, but the barrel is still a 1:9 twist. I didn't notice any accuracy loss in 25 yards, which means to me that the bullet isn't going nuts in the can.

Yea sounds good. He's posted at AR15.com but hasn't gotten a reply so far, so I figured I'd ask here.
I just hate it when gun shop owners or workers are totally clueless.
That's the first thing I thought.
It sounds weird that more twisting would make things worse, but the more I learn about guns and ballistics the more I realize that physics is weird.
