I use a 22 gauge as well........I think hoog's are blunt tip,,,but I got mine at Tractor Supply and they are regular pointed.....I just take my dremel and grind the tip off nice and smooth and it works perfectly.......the little plastic one that comes with them are okay, but i find that they bend and/or break VERY easily, usually after one or two fill ups, for me,,,,,,,,,hope this helps!
