Dart projectile collide with another dart in the board

Hi,

I'm writing a darts game and everything is going great. I'd like to be able to add a bit of realism to the game for when a dart hits another one in the board. The trajectory of the dart is calculated manually with no rigid body or colliders at the moment.

I've had a play around with rigid bodies and colliders for when it hits, and I have had some success, but it doesn't move how I want it to. The pivot point for the dart is on the tip, but the rigid body moves around the centre of the object. Also, it doesn't always move enough and is still "colliding"

Are there any suggestions of a way to do this? I don't want to change the trajectory code as it works exactly how I want it and the game has been balanced. Is there a way to calculate this without physics? or if I do use physics, how can I make it move around the tip of the dart and so they are no longer colliding?

Just to note - this is in C# and for mobile.

Thanks
