308 subs

[billn17]

Well I finally got around to loading some subsonic 308's. I used 215gr hybrids with 31.2grs of WC872 and a OAL of 2.80. End result was 1023 fps. I started at 45grs and worked my way down 10% every 5 rds.

This was done with a savage 10th with 24" 1/10 barrel finished with a thunder beast 30P1 suppressor.

Addition to the above, be very careful going this route. It is possible to have flash back or secondary loading a slow burner and so little powder. That's why I used 215 hybrids. They are so long that they take up some of that extra space.

I have a rem 700 aac in 308. I shoot 210 bergers and 208 A-Max in mine. I usually run 10.5 grs of IMR trailBoss at about 1080 fps in my gun.

Do you use any filler?

I use hornady 168 gn bthp with 8.5 gns of unique.

I cant make my self shoot the 215's below the sound barrier, my wallet wont let me.

No filler is nessarry with IMR TrailBoss. Its for cowboy action guns . Look for a pcture on the internet of it. You use around 4.5 grs for 77 gr 223 loads i think. It with 210s fill up the case on 308.
