damn you masterlock!

so, i have this rifle. and i have this little three number combination trigger lock for the rifle. the sort where you set your own combination.

a while ago, i figured out that i seem to have forgotten the combination. all my usual sorts of three number combinations have failed to open it. even more annoyingly, spending part of the afternoon trying the entire numberspace of possible combinations has left me with a sore thumb and a still-locked rifle.

i'd hoped to avoid destructive methods, but i guess i'll try that next.
