Well the velocity has surpassed your expectations. Now you've got to find a way to save cases for more than one shot. I think if you back down a bit you just might get that 3300fps with less powder than I need to get 3200fps!
That would be a good thing!
If you can get to the 3200-3250fps range with 60gr or so and use brass more than once I think you will find life is very, very good. Good luck!
