I tap them through using a screw, backwards. Perfect.

I just put the screw in a few twists by hand then tap it.
If I had to go really deep to get some firm stuff then I tap 1st plug in
all the way until it bottoms out using above method then tap a 2nd plug
into the remainder of the hole.
Make sure you "unscrew" the screw (check it's loose) when knocking in
the first plug or it can expand prematurely before getting to the end of
the hole.
Snip off any excess with side cutters.
Now your long screw will expand the first rawl plug without and problem
or risk of it pulling out on tightening.
No need for fancy fixings just the cheap old red ones for most jobs.
