I bought from Mouser 100 each of these high HFE transistors with the intention of getting matched pairs out of them. I got them in ammo form so each type is from the same batch.

On testing, using a DMM with hfe, I find that all the 546Cs are in the 500 range & all the 556Cs are in the 400 range. I need closer matching than this.

I have a small no of these from another source & they are the opposite (BC546Cs 460-480, BC556Cs 500-520).

Anybody got any complementaries that would match for swapping?
BC546C range 500-520
BC556C range 430-460
