FieroCDSP said:My main question is why you'd need such a round for SD... The 10mm is a respectable round, but I doubt there's a lot of difference between a 180gr cruising along at 1000fps and one at 1200fps.
FieroCDSP said:You might get a bit more penetration with the 10mm, but in most SD shoots, that's exactly what you don't want. I'd also have concerns that a bullet that is designed to expand and retain it's structure at 1000fps might fragment at the higher speed.
