The load data from Hodgdon shows both powders with identical info.
So, they must be the same or close enough to be thought of as the same.
But mixing them is supposed to be a NO NO.
They might not be exactly identical.
Don't even mix different batches of the same powder.
There might be some variance, batch to batch.
That's why we're supposed to work up loads with any change of components.
Especially if the loads are anywhere near max.
Can't ever be too careful when messing with gunpowder.
