rifle sub sonic, suppressor question

Has anybody ever killed Bigg(er) animals like a hog, or deer size with a sub sonic rifle round? What cartridges would best fit this situation? And finaly, in regards to the repot of the gun and sub sonic noise. Once your round reaches the speed of sound you get noise. So, will a round breaking the barrier by 50 fps be any more quiet than one cruising 1000 fps faster? In my mind I'm thinking something like a bolt action .308?

Re: rifle sub sonic, suppressor question

I should have also mentioned that I do own one tactical solutions can that is on a 10/22 custom gun. This .22 was my first build. Nothing crazy but works for me. Houge stock, Tactical Solutions 16.5" barrel, Tactical Solutions action, Volquartzen trigger topped with the Burris 3x9 with 22LR ballistic plex.
Now I want to build something thats kinda the same ..but BIGGER!
Even if it were necessary to shoot supersonic with a 308 to kill a hog out there a ways I should think I could still load it way down and it would be a much quieter 308.
Thanks

Don't be fooled by the hype. You get noise, just less of it even with Sub's and a suppressor. You just won't get a loud sharp crack, more of a hollow "thump" or "thud". If you are willing to spend enough you can even get one effective enough to make the sub sonics sound more like just a big "whiff" but those cans carry a very high price tag.

Such a rig seriously limits your killing power so short range is going to be the rule.

Now you can where legal get a suppressor that will work very well at noise reduction with any caliber, even the 50bmg which does not then give you the same limitations.

If you want to go the sub sonic route then the .30 whisper would be one to look at. Combined with a suppressor it's very quiet and still can deliver enough energy on target to be effective on deer at a hundred yards or so.

You also need to check your state's game laws as suppressors are not legal in all states for hunting.

There are some very effective means by which you can mask/reduce the sound signature and flash without the use of a suppressor which are perfectly legal anywhere but they require a little creativity and are not at all easily portable such as an insulation lined culvert or barrel which works great with smaller calibers for prone shooting on a range or big field. Thes work essentially as just big expansion chambers and contain most of the blast within. You just need a hole on each end large enough to sight and shoot through.

Price and portability along with your local and state laws are the major factors which come into play.

Re: rifle sub sonic, suppressor question

Energy is way low on the 30 whisper even as close as 100. But energy is not everything. If you are good with shot placement a 30 whisper will kill the heck out of deer and hogs even at 1100 fps with 200+ grain bullets. The bullets do not necessarily expand but often exit probably after tumbling through. If brass was easier to make or available for the 50 whisper that would be the way to go. 750 gr bullets even at 1100 fps smak stuff.

The 30 whisper even with 240s only has 800 ft lbs at the muzzle. The 50 whisper subsonic has about a thousand ft lbs more energy than the 300. That is shooting 750 A-max subsonic

CH4D makes dies for the fifty whisper and PTG makes a 50 whisper equivelant reamer, but the pain is the brass.

Re: rifle sub sonic, suppressor question

i have a custom 300 whisper built on a rem 700 that i shoot the 220 gr SMK's at just under 1000fps and I have a suppressor for it. it's very very quiet.

i've killed 3 deer with it, and while it does kill them dead, you do need to think more like your bow hunting with shot placement. the best thing to do would be to clip a rib on the way in so the bullet would tumble a more than it would otherwise.

they are not ideal deer killers, but do work.

good luck, it's a fun round to play with, but for strictly deer hunting i might look elsewhere.

I have a buddy that has a single shot Encor in 45 ACP 22" barrel with a suppressor. It is so quiet that you only hear the hammer click and when the Speer 230 gr. Gold Dots hit the target.

It holds less than 2" groups at 50 yds. and boy do those Gold Dots expand.

joseph

PS: I don't know of 30 caliber rifle bullets that will expand like pistol bullets at such slow velocity.

Re: rifle sub sonic, suppressor question

You might try looking over at silencertalk they have a thread with pics of deer kills suppressed using sub sonic rounds. I have shot a few hogs and a coyote using sub loads, all shots under 75yds but had no problem at all, it was a 308 loaded down with 220gr.
I have been looking at the 458 socom for awhile now. Basically a 45-70 bullet loaded for an ar-15 shooting sub loads suppressed with a ton of knock down power good probably to 200yds. Thing is the bullet drop is crazy so you will be dialing for those shots. Either way it is different than long range shooting but just as fun.
