Will any of you be using this?

It seems the numbers either look very promising or very optimistic, depending on your viewpoint.

I will be giving the Superformance a shot (pun intended).

The data is also available here:
http://data.hodgdon.com/cartridge_load.asp

I tried the Superformance on my .280 Ackley and .264 Gibbs. The results were just a little slower than I get with Vhitavourie N 550, so I did not proceed with it. I had to do a lot of reserch to find starting loads since there was no data for these catritridges. It may work well for the specified cartridges and maybe later formulations will offer something for me.

3400 fps with a 150 gr bullet in the 300 WSM is pretty impressive. 3580 fps with the 80 gr TTSX in the 6mm Rem is pretty close to 240 Wby performance. It looks like Superformance powder deserves a little testing. The next trick will be to find some. Anyone else out there tried this powder in either of these calibers??

I will wait for more load data.

Superformance = Kaboom. Chasing velocity will get many new reloaders in trouble. IMO

Looking at how many charges are compressed loads one may not be able to put too much powder in the case to blow themselves up .
