Seems like quite a bit more striking force is used compared to when I bump a lock. It also appears that you have cut away more of the shoulder of your bumpkey. I also use a slightly different technique of applying a small amount of tension to the blank all the way through the bumping process. If the lock does not open with the first strike, I release tension letting the pins fall and repeat the process. I will try your techniques and report back in this thread, please try mine and report your findings here.
Also please let us know the brand of lock you were bumping. It appeared to be a kwikset, but the video was dark and I could not be sure.
Thanks for the video
