First off don't buy into the "brush gun theory" that the bigger slower bullets won't deflect as easy. This simply is NOT TRUE! A "brush gun" is a short, light in weight and well balanced carbine like rifle that is easier to carry in the woods then a regular full size rifle is. It has nothing to do with "bullet deflection" I have read article after article that said the lighter and faster cartridges deflect less then the larger slower cartridges do! The bottom line is.......make sure you have a "clear" shooting lane! Have people shoot through brush and kill their game, yes. Airplanes have also landed without their landing gear.......its just not the preferred way of doing it! :shock:
As far as guns and cartridges go, there are quite a few of them. The most common kind of "brush/woods guns" are lever actions. Marlin and Winchester are by far the most popular manufactures of lever action rifles. I think Marlin makes a better gun then Winchester does, this is just my opinion, other's will disagree.
The 30-30 Win. has probably killed more whitetail deer then any other cartridge we have. The 35 Rem. is another really good cartridge for woods hunting. I shot a deer this year with my 35 Rem. The 32 Win. Special is another good one. They haven't made them in a while but there are used ones out there.
You can use a 41 Mag. or a 44 Mag. Marlin makes both and Winchester makes a 44 Mag. I don't know if they make a 41 Mag. or not. I think Rossi make a lever action in 454 Casull. There are a few other cartridges too.
The 444 Mar., 45-70 Gov., and 450 Mar. are killer rifles for woods hunting. They get the job done in a hurry!
Another good rifle for woods hunting is a "pump action". Remington has a model 7600. It comes in 243 Win., 270 Win., 308 Win. and 30-06 Spr.. They use to make it in 280 Rem.. There was a "special run" of these this year in 7mm-08 Rem., 25-06 Rem., 35 Rem. and 35 Whelen. The 35 Rem. has a 18 inch barrel as does the "7600 Carbine" in 30-06. The other ones have a 22 inch barrel. They are a little longer then most "brush guns" but they handle really well and you get a really fast second shot if you need it.
Semi-auto's offer an even faster follow up shot. Some guys like them and some don't. Cartridge wise they simular to the "pump's"
Theirs "bolt action's" that are really short and light too!
