Some folks in a local GShop were claiming their 5.7 was way faster than 2000 fps or so.. more like 28 2900.. I did not go check on it but made a mental note to do so.. the round was also said to not stop in kevlar jacket material due to the extreme speed and small diameter.. I wonder if it will be attacked by the bad politicians that want to ban us having such a capability... ??
As to the 22 wmr... love that cartridge and that is very good speed out of that amt.... I wished I still had mine... the 22 mag kills small game like nothing I have seen before, having been a 22 long rifle fan for a long time. the .204 and the 17 cals. put a real hurting on varmints, but the cost is also a bit high for my tastes... but they work.. of course the 204 is in a league of its own.. like I would imagine the 22 reeder would perform, I guess... I got one of the 204s and it is a barn burner... do not shoot anything you would like to eat and do not intend to pick up with a strainer or a garden rake... it makes a bit of a mess... the 17 tears a terrible hole in rabbits and such and the speed is incredible in the centerfire version... noticeably faster than my 22 mags when I shoot at moving vermin far away... it is almost instantly arriving there with great aplomb...
bang for buck I like the 22 mag, but the fair comparison is the 5.7 compared to the other centerfire speed demons that can be chambered in a handgun for hunting... the 17 rim and 17 centerfire can be stuffed in a centerfire pistol, and that is all I know about... the 5.7 I saw was in an auto format and it held a ton of ammo, by the way... I found that incredible ...
if the speeds would be as fast as I thought they were, then it could be a great, lite, multi-round semi auto with great range and magazine capacity, like for two legged coyotes, and such when hiking, camping, etc... I would not use it in the house either...
