The good thing about going down a standard shortened 308win path for subs is if shooting subsonic isn't your thing, you're still got a 308win bushpig for normal bush hunting use and easy enough to resell.

Remember that true flite makes a short suppressor barrel ( under 17")for a bit cheaper than the full length one. Take that into consideration when getting a quote done.

look forward @tikka to hearing how you get on with the 2 types of bullets

you probably know this already but i will mention it - make sure ALL copper fouling is out of the barrel if you want the best from cast.

Yes roger that on copper fouling.

Just got back from the range testing the Lehigh 168gr CF and the 151gr cast HP.
Getting sub MOA at 100m with the Lehigh 168gr CF/ 9.1gr of ADI AR2205 with a 2.250 OAL at 1024fps and a ES of 8fps. All good for now just need to test a distance once I get the 151gr cast sorted.

Quite impressed with the 151gr cast HP, the first couple of 5 shot groups I got 1" at 60m but still need a bit of play around with seating, I also had to weight the cast bullets into 3 different batch's as they were 3gr out at most. More testing for the next few days while the weathers calm and should be ready to kill some critters. Another thing its seems bit quieter than the heavy weight 194gr + projectiles.

cheers @tikka

i like the sound of 8fps ES . . . look forward to hearing more on your progress with cast

I'm way out of touch, but I shelved my sub sonic because it sucked. Pretty hopeless rifle compared to a .223 or any other centrefire high velocity rifle.

I was given some Leigh bullets to try, and unfortunately to be honest I haven't. Apparently these change the game considerably, making the subs act like full power rounds. One day I'll get around to trying them, but in reality I don't have much need for subs.

Shame as I like the concept, but a silenced .223 isn't much louder and is far more impressive in comparison.

Very interesting comments! Subsonic .308 for bush/close/goat work, and regular rounds for deer should I ever get the opportunity. The only subsonic rounds I can find for sale in NZ are Lapua 200g. I would probably buy a Tikka (yes, boring) which has a twist of 1/11. Would this work or is it bad idea?

Definitly get a tikka. Really easy to swap mags from subsonic to supersonic ammo.
Make your own subsonic ammo. Trailboss and shooternz (?) 151 gr cast projectiles or get the brasso out and buy some lehigh subsonic projectiles.
1 in 11" twist should stabilise 150gr projectiles. You only need the really fast twist for the 200+ gr projectiles.

Get a scope with a BDC reticle so you can use the hash marks for the subsonic loads.
I worked up sub sonic loads in my 708, they are about 15" low at 100yds.

cheers stug. what i should have said in my last post is that i don't reload and it's not something i want to get in to right now. never enough time! hence my interest in the lapua rounds.

Forget about the lapua round other than for plinking and paper target. Your preys deserve better than that , ie Lehigh or cast consciensously reloaded.

Really Friwi? For close range goats? There is another thread going on about 22LR for the same purpose. If you stand by your comment, then fair enough. I'm learning and don't want maim anything.

If, you want, we can organise a weekend where I will bring my rifle all set up with the 150 gr HP sub, and you do the shooting and I'll do the spotting and ranging for you, and you will be able to see for yourself what are the results on those goats.
Pm me if you are interested.

That looks to have potential. First shot was the sub sonic, the second two shots where full power loads super sonic.

I'd want to shoot a dozen or so animals before drawing too many conclusions though.

I will happily accept an offer like that from anyone
