>Getting an A in pellet together with good damage scores is torture though
Idk I found one with just that pretty quick. Managed A flinch and solid rapid fire too. This one I will just chalk up to me being really lucky though. (Though I wish that luck would translate to other parts.)
>nevermind farming Shotgun Shot 3
Also had no issues with this and actually have a tip. Find an orange/yellow dungeon card with chests on the first floor and you can get really any attachment you need really fast by just speedrun opening them and bailing out over and over until you get something good. Only exception to this seems to be AS/GS/WS attachments, but those can easily be farmed if you get a dead stray corpse in a yellow/orange by doing the same thing.
