I mostly hunt muley sheds and have tried a variety of methods for hauling antler. I have tried daypacks, frames, etc. and they all work. Obviously there are plenty of days where you could stuff all you find inside a daypack but I will talk only about the "big load" days where you really get into them. I do not like the lack of flexibility(comfort-wise) of a rigid frame so I ditched that long ago.....p.i.t.a. to have to keep tying on additional antlers to the mess and hate having to waste that much time when I am in them thick. I ended up just switching to "horn ropes". Basically two 1/4"-3/8" stretches of rope with a slip-noose at each end that when the loops are expanded to join in the middle make about 3' diameter loops. As the deer sheds stack up I can just lay em "tines down" over the loop and then just lift up and they squeeze in tightly together.......one bundle on each end. A simple overhand in the middle to adjust the slack and then throw it over the shoulder with a bundle in the front and one in the back balancing eachother out. With two of these I can carry 4 balanced bundles out. I too carry a badlands 2200 and as the previous guy demonstrated it carries elk sheds well along with your other needs for the day and the wide shoulder straps make a nice cushion for my "horn ropes".
A few years ago I hit a helluva little jackpot that produced 133 deer sheds in a day. I was able to carry all of 'em out on the horn ropes in one trip about two miles one way. Won't say it was easy but I can't see being able to do that without my rope system. Cheap method to try and see if you like it and is easy to carry even in a cargo pocket on your pants if you don't like carrying anything but a fanny pack. At the end of the day it is always going to come down to personal preference.
