When in doubt send a load out to have it tested for pressure. Best money you will spend this year. I have a standard load based on Fiocchi hulls trimmed to 67Mm. Pressure and velocity are known and I have them in shot sizes from 7 to 9's. I trimmed 5,000 hulls and loaded them all over a weeks free time. They sit boxed on the shelves and are my basic go to load for all my 12 double needs except non-toxic needs. The only thing I load in Fiocchi hulls is this single load so just be sight I know that the load is safe for all low pressure uses.
