Thanks all.
I put a couple of screws through the back into the wall to keep it in place. Have some shelving to put up too, just haven't got to it yet.
Franks right, more economical to reload, at least for my rifle shells, which is the reason I got into it. What I saved by loading just 1000 rounds of .223 pretty much paid for the cost of the equipment, so it's not that expensive for a beginner setup. I've got a progressive press, which will de-prime, size, prime, load powder, press and crimp the bullet in about 5 steps and could load sever hundred rounds per hour. I don't use it that way though, I usually do most steps one at a time instead, I find it safer that way.
My pistol ammo is still cheap enough that I buy it, but have the plates and dies when/if that changes, just save my casings for now.
