Reloading subsonic brass 308

[sixgunner]

I got some 7.62 loaded subsonic ammo. Made by H-J Ballistic Research. It's Match brass. The package says do not reload. Anyone know why?

Because they want to keep you as a customer?

Could it be non standard brass, like maybe modified somehow to reduce case capacity to allow a more efficient burn with the reduced powder charge used?

I load my own subsonics with 175 SMKs and Trailboss, in Winchester cases. I'd have to look, but I believe I use 9grains of TB, and they are about 950fps. Great little round for quiet shooting at 300 yards and less.
Unless they have something funny with their brass, I don't know why they wouldn't want you to reload them?

To see if the case has been modified fill one and another that you know to be unmodified with water then weight the water after pouring it out in to a scale pan.

Good advise will measure the case volume.

Why do you guys load subs here?


If any of your SOBs have suppressors I hate you all

[sixgunner]

I do not load sub ammo. Just got a bunch in a trade.

Shooting sub sonic 308 is FUN!

Also weigh the cases. I'd worry if the difference is more than once or twice the spread of a batch of known good cases.

Check the primer pocket ignition diameter, they drill those out bigger sometimes for subsonic loads. Check brass to see if any other marks on head stamp. I opened up some of my pistol brass to shoot rubber and wax bullets with just a primer.
