Trouble feeding in my ABS filament

[inventiprint 0]

I've taken out my pla and i've tried to feed in my new ABS filament. This is my first go around with ABS and I'm getting really frustrated. With PLA i just pull out the filament and swap in the new stuff or different color. I tried this with the ABS after setting my nozzle temp to 240C and nothing. My nozzle was jammed so i removed the nozzle cleaned out the print head and nozzle and tried it again. Same thing, nozzle jam. So i sanded down the first few layers of the ABS thinking maybe the diameter was too large. Another jam. Then i increased the temp at the nozzle. Another jam. I've taken this stupid thing apart around 5 times now. I've taken a torch to the nozzle to make sure that it was thoroughly cleaned. I've pushed the filament through the print head when it was cold and with the nozzle removed and it went through without a problem. I put on the nozzle and heat things up and nothing. Jam after jam. I'm about ready to give up on ABS. It prints great with PLA never a problem like this. Are Ultimakers just extremely bad at printing ABS? The ABS is from IC3D. Do they make bad stuff? What's going on?
