Muzzila,
your thinking of a .17 remington bullet thats a 25 grain and its a center fire.This new round is a .17 calibre rimfire based on the .22mag case.It does use a 17 grain V-MAX bullet.From what the artical says its extremely accurate and hits pretty hard but it does blow around a bit in the wind.Its said to have absolutely 0 recoil flatter trajectory then a .22 mag and around the same muzzle blast as a .22 lr.It sound like a great little round to me.Ill be buying one when they come out mid this year.
