Sorry to disagree with ya Grumulkin, but W296/H110 are slow burning pistol powders. That's why you need the amount of powder in the case. Faster burning powders are AA No.5,W231,Bullseye and Unique. Less powder, higher pressure quicker. Blue Dot is right in the middle. I doubt that you can get 1200 fps out of that short a barrel. MAYBE, with a 180gr bullet. Let us know what you find out. gypsyman
