Do Metalmags really work???

They sure do, these shells are .308 and I have hit them with my FX Cyclone with JSB 15gr pellets and bent them up pretty good.

Today I went to the range with some .22 Metalmags.

Using my HW 97k, shooting right in at 650 fps. After a sight in session I thought I'd try shooting some shells off the floor. I hit the chrome 9mm shell and heard it hit the floor. By the sound I knew it had penetrated. To my surprise it went through.

So I thought I'd try the .308's again with the Metalmags.

Wow, pierced right through the other side.



 
That's a fun test!

JSB 15.9gr pellets are fairly soft though. The difference in your results doesn't surprise me. 

A fairer test might be to try again with regular polymags which have the plastic ballistic tip and maybe one other (like a Eun Jin). 

I'd be interested to see any differences in pellet expansion too. 

The topic is interesting to me because I don't have that much confidence in the stopping power of my current 22 cal air guns / pellets. 

I recently bought some new pellets to try for hunting including regular polymags and JSB Ultrashocks. The Polymags were more accurate than I was expecting but not quite as deadly as I was hoping for. I'm still testing the Ultrashocks. 

I didn't go for the metalmags because penetration hasn't been my issue for hunting. I was hoping for something with max expansion to give me stopping power that is similar to my 25 cal guns. 

What's the quality like on the metalmags? Does the tips come off easily?
