308 subsonic

[OR_VARMINT_HUNTER]

Anyone load 308 subs? I'm really wanting around a 200grain area sub in 308 I know u can do it with blackout but curious can it be done with 308?

i use 12-13gr trailboss for hornady 220gr RN because a friend gave me the bullets and i didnt know what to do with them. theyre fun. they hit 9moa lower at 100yrd than my normal loads LOL

YMMV

You can push a 200 Grainer with a little fine tuning right to the edge of super sonic and get a little more range, or lean on a 220 a little more for the same limit! In my Savage 10 FCP and Can, all you hear is the firing pin strike followed by the massive bullet strike on target!

I have used trail boss for 308 , worked well recoil and report like 22mag , accurate enough for me

Look up "The Load" using Red Dot.. pretty sure 308 is a candidate.

220 grain Hornady round nose soft point or similar bullet by Sierra over 12.6 grains of Trail Boss started by LRM primers for better accuracy consistency worked well for me. Both Hornady and Sierra 220 grain RNSP bullets have cannelure and are seated to cannelure in properly sized 308 Win brass. Very quiet and hits with authority

Yes, you need a 1:10 barrel. 1:12’s won’t stabilize very well.

Whats the oal? I'm new to reloading I've been doing 223 successfully so sounds like time to start 308 lol

I don’t recall the COAL but after the brass was sized and trimmed (if some required) to proper length, I seated the bullet to cannelure with no crimp. I tried 13 grains of TB and that worked well good in summer warm weather but in colder lower temperatures you get the supersonic crack occasionally on some shots. 12.6 grains was just what the doctor prescribed. This was in a 22” barrel with a 1-10 twist

i seat the hornady 220gr rn to the cannelure and call it a day

So would ill be using a 12.5inch barrel so same amount of TB should be ok ya?

You will have to experiment to find the sweet spot for a sub sonic load, barrel length may play a part in this, may not!
I haven't tried it in anything below a 17 inch tube my self, So, I cannot answer as to this load in a short length, and your twist rate will effect accuracy with the heavy bullets!

you’ll have to experiment. trailboss takes up a lot of room in a case so you should be safe regardless. id start around 12 grains and work up. ive never ran into high pressure signs with trailboss but YMMV. the thing with reloading is youve gotta tailor your own loads that work for you. as much as i wanna say “this load will work for you” theres too many variables. i hope you find out what works best and let us know. like @Certaindeaf said, red dot works well also and has for many many years.

Volcom has been very helpful with me also and my first chrony is on the way!

 

[Ura-Ki]

Any one ever tried Blue Dot for a sub load? I got a metric ton of it!

Not me but I'd sure look into it.. I mean, lots of guys use 2400 etc
for reduced loads so it sounds viable.

any luck yet or just waiting for chrono first?
