My best suggestion would be to remove the sling and sling studs from your rifle.
Now the rifle is where it should be when hunting, in your hands. Now barrel length becomes unimportant, as your barrel is leading the way through the thick shit.
It seems to have become fashionable to cut down rifles using the excuse that this makes them easier to handle in scrub. I call "bullshit".
Each to their own religion, so do what you will, but I can assure you that butchering your rifle will not make you a better hunter, whereas having your rifle in your hands may.
