Subsonic 300blk projectiles.

Postby AndrewH » Wed May 27, 2015 4:39 pm

Does anyone know what the best projectiles for .308 subsonic are?
I want projectiles that will expand on impact rather than just drilling thru.
Something like the Lehigh projectiles. ( http://lehighbullets.com/products.asp?cat=26)

Currently using Amax 208grn projectiles for my subsonic load.

Subsonic with a BT doesnt sound like a great recipe. Big soft point would work better no?

I have read the 170gr 30-30 projectiles can be used. Could probably drill the tips out more too

Or cast projectiles. veitnamcam has a bit of experince with .308 subs hes the man to talk too

Expanding projectiles for subsonic 308 bore size are pretty thin on the ground.
There is the likes of the liegh high... the 90 gr xtp pistol projectile that expands really well but is just a bit light... and spanners own manufactured 190-240gr jacketed hollow point skived rbbt that shows the most promise of all... However he is one of those 20 projects on the go at once kind of guys.

Pure lead/very soft alloy cast would expand as does a decent subsonic 22lr but you lose out on the sharp cutting edges of a expanded jacket and you woild have to cast yourself as most cast bullets on trade me etc are too hard to expand at subsonic velocitys as they are generally cast for cheap plinking at higher velocities.

I've got the 194gr ME Lehigh 300blk projectiles - they're friggin devastating.. 9.9gr 2205 is what I use. Just like a broadhead but with a bit more oomph!!

Have had good results also with the Nosler BTSP 125gr hunting ballistic tips for my supersonic load 17gr 2205- The exit hole on the most recent goat shot was 2 inches across and although through the chest pulled lung and gut intestines out the hole. The lungs a jellied mess inside, basically Bang - stagger stagger over and out!

Thanks for the info guys.
Carpe where did you get the Lehigh projectiles?
I'm using Sierra 125gr pro hunter for my supersonic load.

Bought them off Oceania Defenses site in Tauranga. They're not cheap tho' $140 for a box of 50 delivered (courier was a bit of that). The Noslers have a bigger frontal apperture hole once the ballistic tip disappears - I looked at the pro hunters but went this way instead. Just sent Kim Jon a few last week so he could try them on game.

The poi at 100 is 16 MOA lower. You need to factor that stuff in with the ballistics of the round too. I understand there is a Speer round too that is pretty good with a huge hole at the front making sure of good expansion. Nathan foster told me about it but reloaders didn't have it at the time. Would be keen to try a few of those for sure.

How are the pro hunters working for you? I use Sierra match kings as my paper punching round (in 125gr) to work up accuracy rounds.

The pro hunters are fairly accurate at 25m they are grouping at about 1/4 inch.
At 100 about 1.5" grouping - that could be my scope its an AR -332 - dot in the middle is about 2 moa I think.

Unfortunately I'll be in sunny Scotland - heading over there on Saturday for the next month.

However if Rushy is going - I could get them off him when I get back....
I'll confirm with him to see if he is going...

I would be interested to try out the projectiles - appreciate the gesture.
