Ok it fits good, and I think it's a delrin tip right? So it's plastic?
When squonking, as with many other things, longer firm pressure instead of quick hard squeeze works much better.
I find with 100% VG squeezing for a good count to three works well and as I go below 1/2 a bottle a 5 or 6 is needed. If I don't refill at 1/3 of bottle but try to milk it to empty I need to hold for 8 or more.
No, the atty was loose.woohooo
Did you have to remove the oring?
