Recommend me powder (s) for 12g and 20g

[Ranyhyn]

Any favourites for a 12g powder using fibre wads pushing 24 - 28gram loads

And

Any favourites for a 20g powder using fibre wads pushing 21 - 28gram loads

And, is there one powder that will do both yet? (I'm expecting the answer is probably no!)

Thanks for your thoughts

Talk to John at Folkestone Engineering Supplies, he's got a lot of info on loading for shotguns and also check out their web site. FES can also supply wads, cases, primers, etc if needed.

Csb5 will do both

Csb5 will do both

Could you point me to load data for this powder because I'm damned if I can find any!!

Have a look on feskent and gualandi website.
They don't list Csb5 for 20g but do list csb3 for 12 and 20

Vectan AS will do both
