Thank you for sharing awesome.

 

You sure you are not spitting cherry seeds into an empty can??

 

I thought he had a FTF!!

 

I'm pretty happy with the results. The downside is that when you build subsonic ammo it performs more like a pistol than a rifle. My 190gr rifle loads perform very similar to my PMC 200gr 10mm ammo.

 

And that is why I’m working up a subsonic .45-70 load with 400 grain bullets! If you are limited by the speed of sound, I want the heaviest, fattest projectile possible. I confess it’s not nearly as quiet as your .308 though.

 

Use the heaviest bullets for the caliber, 230gr for a 308win. With your chrono, load them to about 1050. Bolt guns are whisper quiet. I bought a box of Lapua Subsonic for my 308. I wish I could share the video but after a half hour I gave up. Very cool and quite fun. I’ve shot them in my back yard and nobody could hear a thing (I’m on an Acre but out HOA no allow gunpowder.)

 

The idea was to get the Hornaday 190gr SubX bullet to work with a powder that I had on hand. 190gr SubX is advertised as a hunting bullet that expands well at subsonic velocities. While shooting at paper is useful, I like knowing that the load can be used on game if I need to use it for that purpose. I also found that powders for subsonic .308 loads are getting hard to find, so part of what I did was just a test to see if the powder I have is usable (IMR 4166).
