Titegroup 7.5-8gns. Next question?I'm looking at developing a subsonic 308 load.
What is "the right powder"? Do you mean legally ? Or the most effective powder for subsonic 308 loads ?

Hi,I'm looking at developing a subsonic 308 load.

Probably be more effective loaded backwards.Hi,
Right powder for .243 Win is Trail Boss.
TB isn’t compliant but if you have some you can use it.
I’ve no experience with .308 at sub speeds so can’t comment, sorry.
For what it’s worth, when shooting 100 grain by .243 subsonic, at 100 yards I could collect most of my bullets off the surface of the range backstop. They were slightly deformed at the tip.
Never used them on live targets.
Cheers, Ken.


I almost like the idea of a .350 legend. Hornady make a 250gr subsonic load for them.The above would be ideal ! Load it with big lead bullets.
One advantage of shooting the same ground all your life is you can juggle things round to engineer shots that have the best backstops.I'd be very cautious about shooting anything subsonic if you've got Neighbours near by. You're backstop needs to be absolutely on point. Twice I've known the hornady 190gr sub x rounds bounce after hitting there targets. One went through a fox...hit soft mud then bounced. Luckily I knew there was nothing but open field behind but a friend had a similar experience with 300 blackout. Shot into a bank and it must of hit a stone or something and proceed to bounce up the hill.
They expand alright but just be mindful its a big piece of lead that's being launched rather slowly.
I wouldn't count on either one expanding to the degree that has any meaning, especially on light targets. There surely have been lot variations and/or R&D after initial launch, and current ones might be better.190 and 220gr subsonic bullets from nosler and Hornady which expand at subsonic speeds
I think I need one of these in 450 BM ........................ I don't know why , but I know that I do .The above would be ideal ! Load it with big lead bullets.
But these are the same bullets (.30cal) that a .308 uses so why not homeload .308 subs with these and still maintain the superior supersonic ballistic with lighter faster bullets?The other benefit the blackout has is the ability to shoot the 190 and 220gr subsonic bullets from nosler and Hornady which expand at subsonic speeds, standard bullets will not expand at subsonic speeds so the 100gr in 243 and the 150gr in 308 although quiet will not have the same effect on live quarry.
