The 0.25s are better if you want to make sure your opponent knows that he's been hit with a BB instead of a raindrop or bit of tree or bush or something that 'could be anything'. They are also great if you're outside and your BBs are being blown off course by a breeze or wind, and if you need to punch through some grass. It is true their range isn't as long as 0.2g BBs, but the difference isn't that great, and at least the people who are getting hit with 0.25g BBs know about it so you don't have to waste so much ammo. - Submitted by Al K
