I have the same issue (worn tips), but just lop off 19.05mm with some shears.
I'd love a gaggle of these belt fed sticks, but with a drawer of rarely/never used measurement thingys, I need to preset a frugal face or SWMBO will assume anything goes equipment wise for what can be done at a much lower price point (like using a high dollar chisel to open a can of 15 year old, half used latex)
