Basic attacks with guns work differently, because the actual SWA is calculated and divided as bonus damage. When you 'force' an attack with it via Shinken it doesn't apply. The only times it does are for skills specifically for guns where it uses the attack skill of the weapon, such as with Lead Storm.

Sorry if I'm misunderstanding- I know multiround guns do this on forced autos because they only fire one round instead of multiple after the SWA is divided, but I'm using a single shot shotgun so shouldn't the attack be the total SWA and not whatever it's using that's making it deal such low damage?
