Just use FFFg American Pioneer Powder(APP) instead of old Cruddy 777[:'(]and all that swabbing between shots[]
And lets not forget all those Trip7 stuck breech plugs--Oh joy[>:][>:]

FFFg Pinnacle Powder is good also from what I hear. It's made by APP as well.

Forget all that 25ACP/small rifle primer hooee[:-] and just get some trouble free APP
Cost alot less than all that conversion stuff
