Been packing my BullMaster mAgnum pretty regularly for last year.
Since they aren't making Magnum let alone making bigger ones. Decided to have one made on my own. can't wait to get into the MEGA Magnum!
Could You please direct me to where you purchased that tube.
It's nearly impossible to find a HUGE Tube, I have a 12x5 but it hurts too much to use that one. I can't find a cushion large enough for the opening.
The White ones look like you may have made them from a 3D Printer.
Hope to hear more about them soon.
Thx-n-advance

P.S. This is me with my new 10x2 Tube.
I have been a pumper since I was in College but took a 10 year hiatus & just recently started back
