Thread: Subsonic action

.308 Win, 151gr @shooternz cast lead bullet, ADI military brass, Trail Boss, 1050 ft./sec.

I will keep this short. Riding the quad to elevated positions and then shooting everything from half a kilometre away does nothing to shrink the beergut. So there was no option but to buy a Browning lever action and go back to open sights, forcing me to use my legs uphill, downhill and back up the hill again. Typical shooting range was 25 to 30 yards. Subsonic is a massive plus for the ears, you can blaze away without needing ear protection. It’s much easier for dogs too. And needless to say, you don’t wake up the surrounding countryside.

It’s been a very long time since I hunted with my own open sights rifle. What an excellent mission. Goats are stupid and easy to hunt, but nonetheless you’ve still got to get there, and back again. I really enjoyed it.

they are surprisingly quiet even without suppressor ...great to see you getting amoung them.

Nice shooting! Im getting the same speeds with same projectile in my suppressed 30-30 with 6.8 gr trail boss. 30-50 mm groups at 50 m( sighted in @ 50) Haven't managed to go for a hunt with that load yet but encouraged by your efforts. Incredibly quiet and inexplicably fun to shoot.

they a lot like a .22lr on steroids .... 4times the projectile weight = more than 4 times the preformance.

Good results Dave, need to try them on a deer or two.

Nice work.
How would you compare subsonic with suppressor to subsonic without suppressor?

Huge difference in my 30-30. Suppressor on is stupid quiet. Off, same round, you really need earmuffs. (16" barrel)

Noisier, but not by as big a margin as a really short barrel. Mine is 20”. I find it doesn’t need suppression but haven’t used it in thick timber yet.

It won’t get suppressed anyway. Leaving it as it is. I’ll use ear plugs or muffs when using full power ammunition.

From memory double the weight at the same speed hits with 4 times the force

Nope, double the weight at the same speed is double the force. The same weight at double the speed is four times the force.

I have used Robs casts in 308 and 30-30 both subs and at 1600 fps for 3 years now. Shot reds with the faster load out out to 150yds, worked just as well as a jacketed projectile. Try pushing them a bit faster, gives more margin for error. Should still work with the opens.

This is why I love my Blackout. Zero'd @ 100m on supers. Dial to 6 on the vertical and it's zero'd @ 50m for subsonics. 16" barrel with a DPT overbarrel can.

What kind of subs are you using in it?

I've been using some 208grain Hornady A-MAX, also some reloads from the gunshop which are 220grain (pretty sure they are a Hornady RN Interlock). I use American Gunner 125grain for supers.

with a 50m sub x zero the hornady supersonic 110 vmax groups 9inches high at 100m
