300 AAC Blackout

[tmckay2]

heres an interesting question. I have a remington 700 i shoot fairly long ranges with and have used 168 bthp from nosler and 178 gr amax. the 168 bthp are actually fairly cheap in bulk. does anyone know if you can make the 168's subsonic in 300 blackout? it would be nice to have one bullet size to use. i could use it for both my 700 in 308 and my ar in 300. i know 178 amax can be made subsonic and some people have had pretty good results with them. couldn't find any info on 168's.

I have loaded the 168 and 175 grainers. Not really any published data so I made my own up. Definitely seemed like they were subsonic but I never chronographed them.

were you trying to load subsonic or just regular rounds?

Lol. Not quite sure. Mostly just wanted something that was accurate and would cycle reliably. I used data for lighter and heavier bullets and basically "filled in the blanks" for the missing data for the mid-weight bullets.

You'd definitely be able to load them subsonic, but weather or not they'd cycle reliably is the question.
