I have had a special built .20 Redwolf. There wasnt good enough accuracy with pellets. That project is on hold awaiting a different barrel. I also would like to see more options for .20 ammo and guns. In fact if there were a Aircuda Max in .20 I would likely buy it. With that said the ammo that some manufacturers produce while it shoots good and acurate. The issue I have noticed if you try to go back to 100% lead ammo, that ammo shoots like crap. So then you clean all that debris from the non 100% lead and the lead ammo shoots great again. I would like to see especailly JTS, and Crossman Premier switch to the 100% formula as well. I have barrel bore scope video showing this and have posted before.
