If your shots are close... say 75 yards and under, that little carbine might be a better choice as it would shoot conicals. I would get it in .50 caliber if I wanted to shoot conicals. Seeing you might go after moose. But a .54 caliber will do the trick as well. Its just that conicals are more common in .50 caliber over .54 caliber.

I hunt in thick stuff also and shoot a Lyman Trade Rifle in .54 caliber and never had a problem getting it to my shoulder. I have no idea if the deerstalker will shoot conicals. All of them are made by Investarms of Italy.

I have shot powerbelts out of my Trade Rifle but the few conicals I tried, I was not impressed. Because it is a .54 caliber I normally hunt with 100 grains of 2f and a patched roundball. That is all I need.
