The .30-30 is good. So would be a .44 Magnum lever action. I have a hunting buddy that's got a Marlin .30-30 with a red dot sight. It's very fast for close-in pig shooting.

Sometimes I carry a 12 gauge Remington 870 with slugs when hunting in thicker brush. Mine's got a 20-inch rifle-sighted Rem-Choke barrel and it's easy to get on target and have multiple quick shots. The nice thing about slugs is their tendency to shrug off collisions with smaller twigs without significantly deflecting.

Don't totally discount bolt-actioned rifles. One time I killed three close-in pigs fast. You will be surprised at how fast you can do that with a bolt rifle you're familiar with.

My luck with semi-autos has not been so good. Had a Remington 740 that had tendencies to not feed the second round from the magazine. However, my hunting buddy (mentioned above) has been using an AR-10 in .308 this year mounted with a red dot scope. So far he's killed three deer with it and two of those were running full speed.

Just to clarify, brush guns are considered brush guns because they are short, generally have open sights, and are fast handling in tight situations (such as brush). I don't recommend shooting through brush. For these reasons, lever action carbines are great choices for hunting in the brush.

30-30 is a great choice...so is .35 remington.

model 94 30-30. i have 2 and hadn't used them for a while until this year in close, heavy brush.

Bioguy01 I agree other than a good bolt action can get off a second shot quickly if you practice with it. I think if I was wanting something different I would get an AR-10 in .308. I have shot them on the range and they are really accurate but I probably would just purchase a good bolt action .308.

Browning makes a lever action 308.

Since you have a .308 why not get one in Bolt Action? Your used to the round.

I forgot about the Remington 7600 pump-action rifle. It comes in .308 and can be ordered with shorter barrels, police configuration, etc. The police configuration comes with ghost ring and post sights.

I have an .06 bit this year (except for 1 day) set her aside for a Marlin 1985GBL in 45-70 Govt. GREAT brush gun at 100 yards or less. When I expect to be in over 100 years, the .06 comes out. What I am saying is: Don't discount the bigger calibers because of their limited (under 100 yards) range.
