Great to see someone with a video of a crony in use.

I have these crony's also, when I quote my shooting on the forums these AK lovers always blabber on and on I don't know what I am taking about when I've done test with 7.62x39.

Every AK lover soildly belives the AK is some super hand held cannon !

@Hincesti07 Lol, I see you have meet the Ak fanboys too! They never speak with any fact, they just parrot stuff they hear and read. Thanks for the comment

So does the 5.45 continue to tumble out to 600 yards (supposed effective range)? That would be an advantage over the 5.56, which needs to be above a certain velocity to be effective. Nice video, thanks for posting. I can't wait for more manufacturers to come out with commercial 5.45 loads (Hornady just did apparenly, so the ball is rolling) and some reloading stats/equipment! Then we'll see the real accuracy of this round.

@ImWatchinTheTube, Thanks for the comment. Im not sure what effect velocity has on the 5.45 ability to tumble. In the test i have done I have been very pleased with its accuracy, penetration, and terminal effects. I have a video up on the Hornady V-Max, I think you will enjoy. It shows its terminal effects, they are impressive.

@MACEX1000 Feel free to make your own video. I see you have none

[Dingusmaster792]

This is an extremely informative video. Thank you for posting.

[choopdewoot]

ok now what about psi and how much each tumbles once inside the target?

[a2birdcage1]

The Silver Bear is slower but it's also heavier than the 7n6. Thanks for taking the time to do this video.

@ThePoisonYouth

It weights the same and kicks more ass

[ThePoisonYouth]

@tussery Isn't the 7N24 a lot heavier with a tungsten carbide core?

[UrbanTiger74]

@ImWatchinTheTube The 5.45 and it's design does not require a specific range or velocity in order for it to tumble and yaw. It will tumble and yaw when shot from 8.5" barrel or 20+" barrels regardless. I would surmise that the only loss would be in penetration of hard cover when shot from a shorter barrel.

Thank you for spending time and money on this.

Iv seen 5.56 (Nato Mil) chrono'd at 17ms-1 faster than 5.45 Russian surplus at about 8 or 9 feet but that was a 20" M16 vs an AK74

@realogre32 Yeah you know there is a 5.56 round called the Mk262 that puts any 5.45 round to shame.
