Through all these posts, I am not sure I have figured out exactly what your goal is. If it is speed alone, only in the perfect storm will either of those powders give you more than what you are using now.
I am going to assume just by your original post that you are newer to reloading so I am going to give you one piece of advice, you can sort through it.
Forget the glitter(speed), develop a load that holds a tight waterline to the distance of what the rifle and load can accomplish efficiently. So, just because your rifle can make a hit at 2300 yards, it does not make it a 2000 yard gun.
Random numbers here, just say 1300 yards becomes your apex, you want this rifle capable at this distance. Develop a load where your vertical spread is minimal here. It will carry further out and still do fine to a point. But now, any shot from 100-1300 yards now will be like you eating a big fat piece of german chocolate cake with not one, but 3 layers of yummy frosting.
Most, not all of us go through phases in reloading, from scared to pushing the limits and in between. You run on the edge of hot, moisture, heat, and others are now elements that cannot work in your favor.
Milo-2 thanks for all the info so far. Rifles are mostly a fun hobby for me. I enjoy reloading just as much as shooting at the range. The fun for me is wringing out the best accuracy and velocity out of a rifle (safely of course). I have easy access to a 1,000yd range so that's usually as far as I shoot.
I'm also a hunter, and will probably make this my primary Elk rifle, if I get the accuracy and velocity I'm looking for.
