temp stable

Selling 5# of new Winchester StaBALL HD powder. One can is opened and roughly 500 grains were used in a pressure test. It was determined that this powder was not a good fit for the cartridge, which is why I'm selling. All bought together, all same lot number. Will only sell together for $35/lb...

I have a 6.5 creedmoor with a 26" barrel. Been reading about the high velocities achieved with reloader 26. Claims as high as 3000 fps with 140s. I'm like to hear more success stories and what your data is for it. I'm also wondering how temp stable reloader 26 is?
