Well, this sounds excellent-but the point of the forum is to tap your wisdom as to a specific drill, or drills that you use.
As for myself, I can't think of a firearm I would chance damaging by have it bounce of a floor.
To use a firearm in such a manner would violate the NRA and, by implication, this states law on firearms handling, as well as my sensibilities..
That shows you my priorities.
I would no more use a real "piece" in a driale that a real katana in Seisan BunKai. It would not want to scratch it or mess it up, as I said, my priorities are a trifle 'different".
Having said all that-no disrespect intended-there are plenty of metal non firing pieces available.
However, if the person in question is beyond arms or lunge's reach, I might be inclined to hand over the cash.
Fred Sensei will tell you in Iiado study, that his master does not even allow steel blades, but only the type of aluminum blades of which he approves.
We do spar a bit with padded pvc Bos-in the same conceptual thrust as our empty hand two man sets. We have not done the same with the Shinai, because we have no one to teacj us Iado forms, But Perhaps Fred Sensei might help us .
Finally, my ego is such that even after 32 years of Karate, 20 years of T'ai Chi and Chi Na, and some years practicing one TC "Gim" form with various live blades-I would neveer efer label myself a member of any "elite."
But -everyone to his own, and if you have and specific drill or technigniques you want to share-you are very very welcome to do so.
As for speed-it is king, and relaxation leads to it in most practices to wit, the arm muscles do not tense, until the hand turns over and/or the target is struck.
I had a bit of fun in the "Cowboy Shoots" ()SASS-single actiion pistols, hamered pumshotguns or vintage type doubles and pistol caliber rifles, and, with the time limits, the object is to hit the target.
One gentleman rushed a bit before ltting his weapons re center after recoil, an "lo" a bullet (from a weapon using jacket ammo at over 1000 fps---which is not allowed) and raather ruined the fun for us all by putting a JHP over the drop zone.
So the range is closed.
