Alright alright, let me try to explain a little more clearly.
This is a multiplayer game, which uses the same blueprint (instanced) for each player. There is one character blueprint used - so therefore I cannot cast to another blueprint or whatever.
I am attempting to set the Physical Animation component of the character that I hit - which is the same character controller that I am using…
Here are a few images of my raycast things, excuse the noobiness, I am new 
So essentially when I hit the bone of another player, it applies the Physical animation to me as we share the same blueprint.
I’m sure I’m just being a noob and there is a really obvious node or answer but thankyou for your patience
