as far as your 45acp reading Hoot, that might be all you can get from 6-8gr of powder

Interesting article. I ordered that upper last week. I called Windham and they sent me a ballistic chart for their 9" barrel using Hornady 250gr FTX. They have the muzzle velocity at 2000 FPS. Seems way off compared to the American Rifleman review.
