Thread: Sub-sonic 308 loads

Anyone got a good load for the 308 subs?
Thinking of using trail boss powder, what other alternatives are there?
What pills are you using and are you getting reliable expansion?

Cheers

Ask VC he made some up. theres a thread somewhere here about them. I think 13gr trail boss but he'll put you right what ever it is.

I used 90gr xtp untried on game yet but expand shot into wood dirt etc.
5.5- 6 gr trail boss

There you go. Fark I was way off

No issues with the case not being full enough?
I would have thought the 220grain projectiles etc would be more suitable? Never thought of using the lighter pills

I was told to use a 190 to 200grn projectile with 10-12grn trailboss. BUT I'm not a reloader and haven't tested or used.
another gunsmith strongly encouraged me to not bother, as 30 cal is 'too smal'l - that I needed 'a big piece of lead' to drop an animal even up close.
Admit I'm still interested if I can with my .308 if only for that sneaky shot where I don't want to disturb the natives. . . . . .

I went with that as its a pistol projectile and is spos to expand down to 700 fps. But Im dubious.
You would need a pretty fast twist to stabilise 220gr at 1050 fps.
Edward spanner hands has some proper expanding 30 cal sub pills in the pipeline.

How much longer spanners ?

I just got the call today to fly out next Friday, sooooooooo chances of getting lead mould/tube done before then is pretty slim
Got a BUNCH of ammo to load before then
Realistically, 6 weeks away before I'm home

Might get you to raid the scrap bin Cam for some 3/4" ID tube

How critical is the 3/4 and surface finish?
If your measuring the id its pipe od is tube

Send me dimensions and i will keep an eye out.

What about the pinned halves on vise grip idea. I liked that one.

Wouldn't it be better to use a softer bullet, like an A max?

amax is what i was thinking, also i dont think the tumbling projectile would be much of an issue, will probably make a better wound channel as long as accuracy was "acceptable" for close range shooting

Amax dont do bugger all expansion wise at Sub velocities unfortunately.
You can try some yourself - IIRC (dont quote me) 9-10gr of Trailboss is about right
Dont bother with backward projs.. not a good trick

I wonder if I could push them through my jacket serrater die to weaken the jacket enough?

True that. I just remember seeing somebody on arfcom use them out of a .300Blk on deer, seemed to do the biz
