Tips for axes in general:
For Tac Axe variant we want to drop Weight of the Lex for Strike Down
Tac Axe For this build: Mark II or VII (Unyielding/Carapace Headtaker/ Shred)
If you are struggling in melee, i advice you to switch to Forceful keystone variant, which is much more durable: https://darktide.gameslantern.com/builds/9f362c74-5f5a-4274-a25d-e0786ae4e553/forceful-castigator-lw-melee-h40
