Suppressors sub sonic 308 for what ?

Really? So you aren't tumpling at all? What's your accuracy like?

I assume your asking about subs threw a can?
Pest Control plus the ability to shoot in the back yard, trigger time is trigger time.

Depending the pests ability, range is between muzzle an 250yds with a 175smk or 180gr Sierra pro-hunter.
 
Re: sub sonic 308 for what ?

My dad shoots deer with a can from the house. This way he can hunt from the dining room window open and read the newspaper and have a cup of coffee. Shots are typically 50yd or less.

In a fight environment the subsonic capability to 300+ yard is exceptionally useful in disguising where the sniper is hiding. Shooting sub loads and full bore loads makes the sound reflect from structure differently. In a stress environment this has been shown to throw off the firees and confuse them. Tactical advantage against the confused is obvious.

I shoot pests with subsonic loads.

It all depends on which real world you want to be in?!?!

I mean, you aren't going to be taking down bear with a subsonic load fired from 3ft away, much less any reasonable distance. They just don't have the juice for larger game. Most commercially available subsonic 308 loads hover around the 1,000fps mark (some get up to 1050fps or so) and generate only around 500ft/lbs of muzzle energy if that (it all depends on which projectile is used from 160gr to 200gr+). With a 100yd zero shooting 185gr subs out of a 20" barreled bolt action, I needed roughly 18MOA of elevation to get out to 200yds and by 250yds I was looking at close to 28MOA. I ran the numbers through my ballistics program and got readings of only (rounding) 360ft/lbs at 100yds, 325ft/lbs at 200yds and less than 300ft/lbs by the time I got to 250yds.

Like folks have already said, they make great critter-gitters within 200yds or so in areas where use of supersonic/full power loads aren't practical or advisable. Some of the loads I have used are nearing Hollywood quiet with a can and achieve decent accuracy out to 200yds or so (you can hold pie-plate accuracy at those ranges in decent conditions). Without a can...I really couldn't say how useful or practical they'll be to you. Again...it all depends on what you want to do with them.

Good luck!

BTW...in your sig line..."Koch" is actually pronounced "Coke" so your rhyme is a little off the mark.

240 grain Sierra HPBT at 1050 fps. SSK 300 whisper ar-15 uppper with 1-8 twist. Was doing about 2 moa at 550 yards. I can shoot 1.5 inch groups at 200 yards on a windless day. I have read that the typical 1-10 twist will work well on the 220 round nose bullets.

Re: sub sonic 308 for what ?

what every one else said, plus the fact that while practice is priceless, ammo is expensive...

Here's a math problem for you....what does it cost to load up a round of 308 with a cheap spitzer soft point and 9-11gr of trail boss with cheaper brass and primers? Now take into mind what it costs to load up one round of your fav LR load of choice.

get it? Reloading cuts your ammo costs in half or better....but reloading subsonics cuts that cost again by half or better.

I wouldn't get too caught up in ft/lb figures. I've seen a lot of deer knocked over with 40 grainers at 1000-1400 fps. Less than 100 ft/lb of energy.

Subsonics are good for removing problems when you don't want to make a lot of noise.

I believe in a polite society and shoot SS 7.62x39 & 7.62x51 in my own backyard
through my M14 can without disturbing the wife, the cats or the neighbors.

Yes sir they will, thats what I shoot.

This is why I shoot a lot of cast lead. The most expensive part of the load is the primer and gas check. I shoot cast lead from my 30-30 for about 9 cents a round.
 
Re: sub sonic 308 for what ?

I never thought about lead, what a great idea, I have been making SS loads with 180grn round nose pills, 10grns of Trailboss, 215 mag primers, never chronographed but quiet through my Shark.
 
Re: sub sonic 308 for what ?

I use 220gr Sierra Prohunters that I have hollow pointed for deer hunting and animal controle , they will hold 1 moa at 100yds from a 20" 1-10 twist 308 launched at 1000fps run through a custom made suppressor. I've shot paper with them out to 400yds and they still made nice round holes , moa was about 6" , mostly due to wind though.

the energy is greatly reduced but at the ranges I use it at (100yds and less)350ftlbs is plenty especialy since most shots are head and neck shots , though that bullet will pass through a 110lb doe at 100yds shot behind the shoulder leaving a quater size exit

the energy this round produces at 100yds is about the same as what a 9mm produces at the muzzle so everybody saying that its not effective on humans is very wrong , you take a sub sonic 308 round through the chest with a bullet that will expand some and your pretty much done

I use a load similar to this a lot and it works well. 8.5 TB and a 170RN lead worked great in 7.62x39 also, hollywood quiet with YHM Phantom. Lead below 1100 is GTG.

No, the bullet still makes a sound when striking something (animal or target)

I don't know about Va, but some states have pretty liberal limits on deer, and allow use of suppressors on game.

Not game, but a guy nearly local to me, in a thread about subsonic .223, reports pitch black/ GenIII NV coyote calling with 4-5 respondents and the ability to put 2-3 on the ground before the others figure out there may be a problem. With supersonic or unsupressed, coyotes rarely hold still after the first shot.
 
Re: sub sonic 308 for what ?

The whisper is a fun MOFo for sure.
At night, with a rifle mounted light on target, one can watch the bullet's rainbow trajectory to impact. Neat stuff.

Mine is also very accurate (.5moa) out to a hair over 220 yards which is as far as I have run it.

The hammer dropping and the bullet impact is louder than the round going off. Supressed of course.

I built a whisper cause I didnt want to phuck around with downloading a 308.
 
Re: sub sonic 308 for what ?

RHutch, what subsonic loads are you using with the Whisper? I've just started shooting mine and must be using too slow a powder because it is way louder than I would like.
 
Re: sub sonic 308 for what ?

shot some 308 out of a ar10 and it doesnt have enough to cycle the gun obviously but but hit out to 300 half way decently
