 Veteran Build - Warhammer 40k: Darktide 

My take on the Death Korps build allows you to shoot infinitely, rarely if ever consuming ammo because of Surgical and Shock Trooper, hence why I dump Ammo on the Lucius Mk IV Helbore Lasgun - it might not shoot fast, but it will usually one-shot its target.

I take Infernus quite honestly because I don't think any of the alternatives work in this use-case - sure, you could run Hot-Shot, but how often are you shooting this into crowds? That's what the Munitorum Mk I Sapper Shovel is for, which you'll also notice I run without Uncanny Strike because this is meant to be used more as a horde-clearer than an armour-killer - that's why I suggest Krak Grenades with Grenade Tinkerer. Armourbane and Sustained Fire are probably the best competitors to Infernus, but I like the extra DoT that is all but guaranteed because of Surgical.

I also want to quickly note that, regardless of which Shovel you're using, you should be dumping Mobility over Defences because the Stamina efficiency is worth more than a small increase to movement speed and Dodge distance.

I also use this same Talent tree on another build, so I'll touch on that quick:

My Vostroyan runs a Lucius MK V Helbore Lasgun with dumped Charge Rate, running Carapace and Unyielding Perks with Armourbane and Weight of Fire; and a Turtolsky Mk IX Heavy Sword with Flak and Maniacs Perks and Deathblow and Rampage.
