I'm decent at SPP'ing deadbolts and even the one's with moderate security features like Schlages with the 4 spool pins. But I've had a lot of trouble with the very new masterlocks it seems like the springs are so stiff I can't feel what I'm doing. One in particular has been a real issue for me. It's a MasterLock Magnum Solid Body with the boron shackle and re-keyable features. I've seen it picked many times on youtube and the like. Does anyone have experience with these "magnum" locks that could provide some knowledge to a newb?
Thanks in advance!
