Loading some 12 Gauge SD rounds, need some wad help

[nogaroheli]

I got a MEC 12 gauge press at an estate sale 7 or 8 years ago, it's stayed in storage until just recently. It came with some older primers (Federal 209, just plain 209) that are probably the same vintage as the wads in the picture that came with it. From what I can tell the wads are very similar to the Downrange Pattern Control wads-

At first I just want to load some 00 buck rounds to get started and see if reloading shotgun is for me. I'd prefer to not buy a bag of 500 to try it out, is it safe to use load data for those wads? Or are wads a super critical part of the equation?

I'm also planning on just using some once fired Winchester hulls from the Wal-Mart 100 rd target boxes.

Thanks!
