I have a few boxes of FACTORY Norma ammo using 250 grain Woodleigh roundnose bullets that chronographs an honest 3200 fps. I have pulled bullets and weighed them and shot it over 3 chronographs. Not sure how that bullet would hold up at those speeds but it gets your attention when you pull the trigger!
They are loaded with pixie dust I think.
There are a lot of new powders I haven't tried but three of the best have been R17, MagPro and R19.
