Well, Tactical/LBE and hunting vests are very different.
Seems like you need more of a hunting vest to me, and the best advice I can give you on that, is to go in to your local sporting goods stores, and try some out.
"Tactical" or LBE's are a completely different rig which most of the time don't offer padding on the shoulder. The reason behind this, is mostly based on the way a combat rifle is shouldered more towards the center of the body, and also the fact that it doesn't "kick" as much as the large hunting cartridge.
Some of the cheap/airsoft vests do have a padding on them, but in real life application you'll see how soldiers and LEO's tend to go towards the chest rig platform with simple unbulky straps instead.
Thats just MY take on the subject, however I suggest you go with something that fits you well, and is comfortable. There's no reason to drop too much coin on a heavy duty rig if your just hauling 5lbs or so of gear.
PS - You might want to look in to a good pack as well. For hunting I use a Maxpedition Monsoon, and have a very nice rubber pad on my rifle.
