If cost is a concern and Wolf is considered, I'd take a good look at Silver Bear ammo. I've been shooting it for a while and have well over 4K rounds of it through my latest pencil barrel build. It's it a bit more of a stout round compared to the Wolf and it burns a bit cleaner. I shoot the 62gr HP. The only problem I've had with it is an occassional failure to extract. It does that when the chamber gets way too dirty and this happens sometimes because I've been running it on a piston upper that I don't clean very often. I just run the chamber brush through it and all is fine again. At less than $5 a box from cheaperthandirt, it's hard to beat for plinking ammo.
I don't know why opinions of the PMC stuff always comes with qualifiers. I've found it to be good stuff. It isn't tack driving stuff, but neither is any M193 ammo. It is a bit underpowered, since it's loaded to SAAMI spec, but still good ammo. Lots of places have it for around $7 a box.
And still, if cost is a concern, you could also check out the Speer M193 (stamped LC) at surplusammo. It's the same price as the PMC. You might also want to take a look at the BVAC reloaded stuff at cheaperthandirt. Something around $16 for a box of 50 55gr FMJ loaded in LC brass.
I'm gonna keep shooting the Silver Bear. If you go the Wolf or Silver Bear route, you MIGHT want to pick up an extra extractor, as the steel cases are sometimes rough on the extractors. As for the Wolf, (if memeory serves) stick with the military classic. It's loaded a bit hotter than the other stuff.
