Hello mate welcome to the site..
You will most likely have an issue when trying all pointed pellets in those and other type rotary magazines, those magazines only really like Flat head and domed pellets and most prefer the flat heads.. I use RWS C02 target pellets in my beretta 92fs with a rotary magazine..
May i ask why you want to use pointed pellets? im guessing for penetration?
As for the umarex morph 3x, i have had one of those, and i enjoyed it, read my little review it might help you..
