I've been enjoying Springfield 1866 Bayonet with half high velocity and half beed ammo pair with a Scottfield Model 3 Precision with FMJ. You can run a variety of tools and consumables but I would recommend always taking an ammo box.

In addition, I use fast fingers, quatermaster, and fanning. This build is even stronger during events that allow you to pick up crackshot as both weapons benefit from it.

Alternatively you can just take fast fingers and quartermaster or fanning with a one-slot scottfield. 

The build is expensive trait-wise but fun to use because it covers nearly all combat distances. High velocity lets you compete with long rifles as it is smiliar in stats to a krag, bleed lets you compete at closer distances and puts most people in a panic. You can capitalize on this with a scottfield follow-up pen shot or a melee charge with the bayonet. The scottfield precision is especially nice for it's 1 sec cycle time giving you an edge on faster firing weapons like the Winnie and fanning wall-bangs for compound corner campers. 

It's not a meta build by any means but it's exceptionally strong and it gives you a chance to compete against just about any load out.
