Thread: Superformance just coz.

Superperformance is good but it's really hard to get published data on it, although there is some around now. It's also not listed in quickload unless has been recently.

The other thing is because it packs in so tight the extreme performance loads are quite a bit heavier than standard powders that you would load for a certain cartridge so you are often going into uncharted territory, so need to have your wits about you.

I think that's why most people just can't be bothered.
