That is an insane idea.
38 and 357. ridiculous. those are not good calibers for game. what about 30-06, 300 win mag, or 270.
leave to someone to screw this thing up.
There is no barrel...bullets gain velocity through powder charge, barrel length and burn rate on the powder....there is no barrel....so there is very little force being applied to the bullet....but...
Even if you could contain the blast....I'm guessing that it is shooting around a 125-150 grain bullet.......your arrow is most likely beween 300 and 400 grains (with out the head)....every action has an equal and opposite reaction......just a thought, but how fast does the arrow go backwards when that thing goes off?
A .357 fired out of a two inch barrel (which this does not have) will generate between 400-500 ft lbs of energy.....the general rule of thumb for deer is 1000 ft lbs of energy. I doubt that this even generate 200 ft lbs with no barrel (about 20% of the recommended energy for a bullet kill on a deer)......my bow has damn near 100 ft lbs (about 250% of the recommended energy for an arrow kill on a deer)
I'm not saying that they can't kill big gam......I also wouldn't say that you couldn't kill an elk with a 30lb draw weight and a 24 inch draw length....if it all goes just right...you could kill an elk with this set up...but nobody would recommend it.
This bs set up has no where near the energy a bullet needs to be shooting big game...period... and anyone that would try is very uneducated on what is needed to harvest an animal quickly and efficiently..
I'll guarantee that any bh out there will be much more deadly than this joke....bullets and arrows kill in two entirely different ways.....an arrow out of a gun would still be deadly.....a bullet out of a bow...not so much. It's just going to wound animals...these should not be allowed for big game hunting...we have rules an bh cutting diameter and in some cases arrow weight....theses rules are to keep people that don't know what the he11 they are doing from doing something stupid.....we are going to need the same rules for these.....damn it...I hate rules....but this is just stupid.
