If I could get them to 2800 or 2900 fps that is as fast as I like to shoot any round. Am I living a pipe dream or can I get there from here? ...

I haven't seen any real data yet that would allow you to hit these speeds, and I don't think the bullets would hold together or have the correct terminal ballistics at that speed, but I could be wrong. ... Also, the concussion/ recoil impulse would be close to unbearable I would surmise. Really, I don't know what you are planning on hunting, but that would be one insane round. ...

#1 on the very top of the list.... LILGUN.
#2 and one you had better respect.... 296
#3 is one used mainly for heavier bullets over 275 grains.... 1680.
Anything else, well... You would be better off leaving them alone.
If you study the data contained on this forum, these are the only three powders that get serious attention right now. If you are new to the cartridge, I would strongly suggest that you stay with LilGun and slowly work your loads until you get a good grasp on how this cartridge performs in your specific rifle.
As for the burn rates discussed in the OP, I don't know where you got those numbers but when it comes to safety, the best thing to do is always remember YOUR SAFETY COMES FIRST. From what I've learned so far about this cartridge, I see no reason to tinker with any powders other than the three I've listed. But that's just MY PERSONAL OPINION to keep ME SAFE.
