Match 300 blackout subs.

[BigMike]

Range day was fun but a flop. The sig elite match and sig marksman match 300 were anything but match. They were running all over the board between 830 fps and 1100 fps. They missed something somewhere. I'll add pics of the chrono data when I get it labeled so it's not confusing.

Looking for a recommendation for a good match grade 300 blackout subsonic round.

I’ve never put them on a chrono, but I like black dot ammunition out of phenix city Al. Ymmv

No chrono, so these may not be flying subsonic. I’m loading these.
190 grn. Sub-x , 12.5 grn. CFE-BLK
Out of my Ruger American Gen1 with a Sandman-S.
They run well out of my suppressed SBR also. Great for dispatching muskrat, beaver, hogs & coyote.
Zero affirmation from a few days ago.

Last time that I shot SIG Elite Match 220grn subs they were very consistent. Been a few years.

Maybe it’s a bad batch?

I've been running Corbon match. Seems to work well in both my Sig Rattler and
Savage Axis.

I bought 3 new boxes when I picked up the rifle and took 3 boxes I picked up 3ish years ago. The box and name have changed but the sig item number matches. I've had very good results out of every sig ammo I've used. Not sure what happened with these. I tried two different suppressors and no suppressor at all.

Remember your barrel is still breaking in. It’s going to take some time to get true velocity numbers

True, but it usually settles and gets a little faster. These have an almost 20% spread in velocity.
