Tried rubber mulch in two different plastic tubs already on hand, but both had weak lid/attachment hardware & bowed too much for my liking (would also let pieces out here & there, & the mulch would get loose).
Found the exact tub @intenseaty22 used in his video at Lowes & bought one. Lid is sturdy & is secured in six places- one big one on each end, two smaller (but still substantial) ones on each side. A larger, deeper version was there too, might be a better bet for big bores. Mine is doing fine with up to 60+ fpe in .25.
