Help with Master Lock?

[22Delta22]

So since everyone started picking I've had people just give me locks. I've always got through most of them. Maybe not fast but I did get them open.

Anyway I was given a Master ProSeries 6321. Looks like a "high security" lock for storage units and such. The only thing thing is they keyway feels small. Have trouble getting getting the pick and tension wrench in. Any advice?

And there is also a hole that looks like it's for an Allen wrench. Is that a bypass thing? I'll incluse a picture if I can figure out how to get one on here from my tablet.

Guess I can't. But here's here's a link to facebook photos. The hole I was talking about is in the second. You can see the keyway, then a dimple in the plastic, then below that the hole.

I cant be sure, but it looks basically like a Master 911 but black with a shrouded shackle. If it works the same way and has the same driver pins as the 911, then it is full of spools and has no spring presure on the core until it is turned a little past the pick point. If it is like the 911, then here is a video. BosnianBill can do much better justice to the picking description than I can.

I think one is a drain hole and the other is for the missing cover. Whatever they are, they won't help in bypassing.
