Thread: Loads for 300 blackout

Hello - I have't shot anything live with mine yet either, but after a lot of reading I have settled on the 125 Hornady SST as it seems it mostly lives up to its claims to expand well at velocities you'd expect out to 150M or maybe a wee bit more.

You can get Fiocchi ammo for $36 a box of 25 ready loaded with 125 SST's, or roll your own, I'm using N110 as Quickload says it has a 100% burn (and therefore low muzzle pressure = low noise) and it shoots great in my rifle (a CMMG 12.5" barrel).

I get 2025 fps with the Fiocchi's and 2045 fps with handloads, so for all intents and purposes - identical. The handloads shoot a bit better than the Fiocchi's but both are very good, way better than you need to reliably shoot deer (or even smaller stuff like wallabies) out past 180M.

The Fiocchi shot really well in my cobbers American - better than my AR
