I'm not sure what all of the fuss is about...I mean it's ONLY 2 shots through the same hole.......
For an impressive demo, go with TS and WATCH AND LEARN when he puts an entire magazine through the same hole and he doesn't take 30 or 45 seconds between shots, more like 4-6 seconds.
TRIGGER CONTROL, SIGHT ALIGNMENT....he preaches it, I practiced it with dry fire and now I'm proud to say I can do 2 shots (a small increase in hole size but definitely not 2 holes...hole incresed by 10-20%.....more practice and I'll have it down.
Shooting is a perishable skill and for anyone that does get to shoot nearly everyday, they can prove it to you....just give them time off ...it takes a warm up period to get back on track, yes it can be quick and the more previous xperience the faster it comes back.
BTW, to incapacitate a human life form, don't put holes in holes, spread them out to make more things bleed...just a public service announcement from your local trauma surgeon
