.22 AR drum mags larger than 50 rounds?

[little_airwolf]

Is there such a thing as a larger drum than the Blackdog 50 round drums?
GSG has a 110 round drum but they have has issues. I've seen alot of issues with the blackdog drums.
I have three 25 rounds mags and have had NO issues with them!
Thanks Andrew

Promags are notorious for jams but my blackdog is good!!
