I examined some material from my collection now. I have specimens with orange legs belonging to Sepsis punctum and S. violacea from Dalarna region determined by Ozerov. This is not so far away from Ångermanland. In punctum smaller specimens have more dark legs, there is the opinion in literature that specimens from dry habitats tending to have black legs, and all of my very large males have those orange and in comparison thick femura as shown in your pictures. Finally I have a female with orange legs from Dalarna determined as S. punctum geniculata. S. geniculata is synonymised in 2004 with punctum by Ozerov.
I still say Sepsis cf. punctum to your fly.
