RamSet For Concrete Nails Quest's ?

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, B

Hmmm. It depends alot on what you are trying to fasten.
In court - if you tell the judge you were trying to hang some shelves, when your drill slipped and bored 5 holes through your wifes skull - well, it's just not very believable.
Now, on the other hand, if your ramset slips, its entirely possible that an errant nail or two may be sent flying.

So many questions! Have you used a ramset before? Does the kit have different charges for different hardnesses of concrete? How old is the concrete? (Age determines hardness) How thick is your wall? What's on the other side of the wall?

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. bill

if using it in old concrete it may spall the concrete. and the nail may not hold. I use a roto hammer and a rawl pin or a tapcon screw now.
