superotto80- welcome to the disease for which there is no cure....you don't want one either.
As for the question and your info. I have hunted with a 28" barrel on my Nova. It worked well. The issue is the swing radius- if you are in a wide open area then the barrel isn't as big an issue, but if the brush and woods are tight, you have a swing problem.
My other concern for you is the choke. I am sure the Rem Choke is ok, but I would seriously concider an after market choke. The best thing for you to do (IMA) is get a couple of chokes- one being a SSX for the Rem., there are 100's of opinions on this, but for the money (under $40) you can get a great choke (The place I got mine sent it cleaned of grease and answered any question I had). Then get a cross section of shells (3's, 3 1/2" and shot sizes 4, 5, 6 and companies. I have had great luck with Federal, but other guys like Rem or Winchester) the piont is you have to find what your gun likes. Fire those at 20 and 40yds to get a base line for all the chokes you have. The one that gets the best pattern and pellets in the kill zone is your combination. Also what sight do you have? If you have open sights and want a good cheap fix, triviz sights by HiViz are great. More of a tech head? I LOVE my EOTech I got from my late brother. It was his on his SWAT entry weapon (AR15) WOW, but it is $350 new. Hope that helps a bit.
Also what part of the country are you hunting. I have met a bunch of guys when i started that helped me is so many ways that lived close. Keep that in mind too.
