Face, no problem, stomach, is that even possible? I did a quick search on Youtube, finding a few slow motion revolver clips, but nothing remotely displaying your described technique. P.S. Thanks for translating your abbreviation. There are so many, I can't keep track. For example, doesn't FTW translate to "**** the waitress"?
Look at around 8:45 when they shoot the 475 Linebaugh (stainless) and then the 500 Linebaugh (Blue). You can clearly see the handgun has rotated almost to the point where the web of the guys hand is touching the hammer. The long haired guy allows so much rotation he needs to use gloves to protect his hand. Edit - I just noticed the 500 Linebaugh in the video is ported. That and what looks like a 7 1/2" barrel does a lot to mitigate roll.
Definitely longer than with a .22 l.r. .... but you would deliver the same energy to a target with one shot.
It depends what caliber you're are shooting. On very light 357 loads (loaded down to 38 special level) as I use for Cowboy Shooting, you can shoot very fast as the roll is very slight. With a 500 Linebaugh and similar, possibly fast enough to put a second shot into a charging Cape Buffalo or Grizzly, but probably not fast enough for a third shot.
Ps. I am not advocating a shooting style/technique. I'm sharing my approach and why I prefer grips that others may not.
I ask because I use handguns for competition only. Hunting with handguns and wearing concealed weapons are illegal in my country. If a grizzly or a bison stormed toward me, I'd most likely panic and do all the wrong things. I would however like to know if firing 5 rounds in your style takes less or more time than using your shoulder to absorb the recoil, which is why I suggested target size and distance. Maximum available time with a 10" target at 25 yards would typically be 14 seconds. "Light" Magnum loads are not permitted in competition. You can find a list of projectile weight (Kulevekt) to velocity (Hastighet) ratio (Faktorkrav) here. The smallest weights in each category state minimum allowed projectile weight. Oh, Magnum I is .357 to .40, Magnum II is .41 and up. On a side note, I've been doing a lot of reading today. I found, among other things, that many modern factory Magnum loads available here are too light for Norwegian competition demands, requiring of us to load our own ammunition. Scandinavia is way too small a market for ammo manufacturers to bother catering to our needs. John Linebaugh's sixguns is also an interesting read, yet I doubt I'll ever see any of their products in my neck of the woods. Pretty tough toy, as long as the cylinder is lubricated at either end for every other reload.
