Does anyone know the capacity ( grs of water ) for a 41 special case ?

Roger

I could just calculate it like this; water capacity of a 44 mag. Water capacity of a 44 Special. Find the percentage difference.
Apply that percentage to a 41 mag case capacity; voila; that is the value for the 41 Special.
Or do the same formula from the 357 mag/38 special data.

Thanks, I'll give it a try

I show it at 31.15 grains H2O

My understanding of the 41 Special is that it is a 41 Mag cut down to 38 special or 44 special case length.

Pi times the Radius (squared) times the height.
