Suppressed 16 inch .308? Any reason not to?

[Black-X]

Thinking about having my .308 700p cut down to 16.5" or so and using it mainly for subsonic loads with the occasional full power load. Any reason not to do this? I can't help but look at the success of the Larue OBR with a 16" barrel and it makes me go hmmm.. At 16.5" it will be short with the suppressor, light, handy, and still reach out there a good ways with full power loads.

I run 2 loads currently. 175gr SMK, 43.5gr Varget and my subsonic load is a Hornady 170gr flat point round nose bullet with 10.2gr of Trailboss. Both perform very, very well currently.

If I really need to reach out there I have a R700 .300wm rifle that is in the process of getting trued and rebarreled with a Lilja 28" blank which is about 2 weeks out (before I get the barrel).

What's your opinion?

that 16.5inch barrel probably wouldnt work very good long range obviously, but if you plan on carrying it around for plinking and what not sounds like it should work obviously not a 1k yard benchrest setup

I would go 18-18.5 inches long , not much longer really , but will make all the difference for your supersonic loads , and still short enough to be good with subsonic loads , RE the friction .

You could do it no problem. Use the fastest burning powder you can. I know a couple guys that hunt with 308 pistols out to 200 yards.

Heck yeah, go short. More fun than stompin' baby chickens!

Ha! Finally got to use that one!

Short, suppressed rifles are fantastic.

Depends on twist. This short of a barrel might not stabilize the bullet when/if using subsonic loads.

Anybody got a picture handy of a 700P cut down this short?

I was worried a bit because of the 1/12" twist of the factory barrel. I'm using lighter 170gr .30-30 bullets as they are supposedly the most (or one of the most) stable bullets for subsonic use.

Here's a pic for ya'...

APA built this on a 700 action, barrel length at 16.5 with a Tac-Ops .30 cal can.

It is very handy and shoots VERY WELL! However, I have found that I like it even more when it is not wearing the can. As for shooting at distance, I have little trouble with it out to 700 yards and had this built to fill a specific role, which it exceedingly does. Hope this helps.

if i have another bolt gun built it will be about 16" every one i've shot that short has shot really really well and only ran out of gas at stuff 800+ which i have other guns if i need to go that far but as far as being handy they are alot of fun

I totally feel you on the range of 800yds. If I didn't have a .300wm I wouldn't consider doing this but right now I'm really leaning towards going forward with this.

Winny, that's badass!!

I was going to do just the same thing with a .308 Remington 700 I have but I'd have to re-barrel it to 10 twist to make sure I don't get a baffle strike. I'd think with anything between 16-18" you can get a full power load with 168/175 to go to 800 yds no problem.

I currently have a Thompson Encore in .308 (10 twist) that I had the barrel shortened to 18" and out of it I'm running the Hornady 180 round nose bullet with 10.0 grains of Trailboss pushing it at 1015 fps - running it through either an Omega 30 or HTG M40 can.

I have a Steyr Elite Tactical that I cut to 16.5". It runs a can, and is more accurate than before. I'm getting consistent 1/2MOA. It shoots great out to 1000. It only requires about 40minutes more adjustment (or roughly 50 inches more drop). I didn't build it for shooting that far, but I had to try it. Typically I shoot inside 500.
I shoot 168 Sierras.

It'll work very well for you within your intended purpose. I build a Take Down rifle called the CRUX with a 16.5" barrel and its performance is somewhat surprising....

I think SC just made a rifle like that for the DM\S-R project in the rifle reviews section.

I love mine! Wanted to post pics of targets and rifle with can on, but my wife left the camera outside and it rained on it.
