N/A Contemplating a Big Bore Bush Gun

Sometimes situations arise that require specific or specialty tools. I’m interested in suggestions for a bush gun- something compact that I can shoulder and shoot at short range in tight spaces like thickets, heavy undergrowth, a pine sappling stand, etc. Might sound strange, but it’s what I want. If I can find something less than 30 inches that would be great! So far I’ve considered:

Evanix Rex-P in .45 (super compact)
AEA Element in .45

Just something I’ve been thinking about on and off. What else can y’all suggest?
 
What size game? Pigs and deer or armadillos and raccoons? That new Rattker 45 is pretty versatile platform for building off from, wirb barrel length and slug weights and power. (As is the 357) You'd have to get in touch with Western or commission someone to make the appropriate twist rate barrel consistent with the slug weight and length.
