powder fasteners are very fast to use, after finding out which load strength
works best.
holding strength is pretty good, but I think many people use adhesives on
the boards as well.
one drawback is that concrete is not a very homogenous material, and some of
the fasteners
are may not penetrate as far as desired. you then can't do much with the
protruding nail heads.
if you're going into brick, etc, i think i would use drilled anchors.

Was in home Depot and saw a small "kit" from RamSet that sold
for only $20. Has a bunch of "nails" for concrete included in various
sizes,
the cartridges, and the handle where you place the cartridges and nail.

Wish to fasten some 2X4's against a concrete wall to enable the
building of shelves there.

Is this Ram Set approach "better," than, e.g., drilling a hole
with a concrete drill and using one of the expandable fasteners
in the hole to hold a screw (not sure if they also have for nails with
this approach - do they ?)

Which is better ?
Why ?
Pros and Cons?

Thanks,
