Why spend so much money on the rifle and then fire crappy homemade ammo?



[Silentindustries1]

@eztred If you will notice- this video was done over a year ago. When hand loaded ammo was the only thing available. And that "crappy" ammo works fine with a suppressor. The goal of that ammo is to be as quiet as possible.

[malleymyster]

can you use .223 brass to load blackout?

[Silentindustries1]

@malleymyster Most of my brass is trimmed .223 brass. The rest is .221 Fireball resized.

@BASEate9 When I use the 220 gr sierra Match kings- about $.47 a round. That is with my brass- add some if you are starting from scratch.

[BASEate9]

@Silentindustries1 Oh ok, that makes sense. How much does it run you to make say 100 rnds?

[Silentindustries1]

@ZeCrazyOnes search for the "Honey Badger"

[Silentindustries1]

@BASEate9 The ammo is loaded with 10.7 gr of AA1680. It needs the suppressor to give the required back pressure to cycle.

[BASEate9]

Looks like your homemade ammo isn't cutting it... 2 misfires

[ZeCrazyOnes]

can the HK416 300 BLK have an internal supressor
