Suppressors db reduction when switching from .308 to .223?

[dcnyli]

Was recently shopping for a suppressor, and in talking with the salesperson he said that I could use the same suppressor with a .308 and .223, but would lose about 2-3db when going to the .223

this is fine with me, but was just looking for confirmation

I do not know what you lose, but I use a 30 cal can on bull barrel .223 and .204. Seems similar to using correct cal can. JMO

thank you….

Yes, you can lose a little sound reduction when going to sub-calibers. It's nothing to be terribly concerned about, it's just not necessarily the optimal setup in some cases.

You can always start with the larger can and later add the can for the smaller caliber later. Chances are you will be buying more in the future...they just seem to multiply.

I don't doubt it… I'm just waiting till i'm in Cincinnati to get my trust and make it happen...

From what I have seen the .30 cal cans usually do pretty well on .223. You lose the tight bore but gain internal volume.

If your not shooting subsonic ammo, the difference is not worth talking about.
The crack of a supersonic round tells the world a shooter is there regardless of how good the db reduction is. Don't believe all the hype about reduction unless your really, really into subsonic. Even the best cans in the world for subsonic work can't reduce the bullet impact noise, so don't allow the sales hype to cloud the issue.

I will be using mostly supersonic, but the occasional subsonic will happen. Is accuracy a concern when swapping to .223?

I think the general consensus is that when used on .223 rifles, the sound reduction a .30 cal can loses from its larger bore diameter, it typically gets back from its larger volume.

You're likely to be about as pleased with a fullsize .30 cal can's performance on a .223 gun, as you are with a fullsize .223 can on the same .223 gun. Except that the .30 cal can obviously hangs more weight out there.


One of the first suppressors I bought was a SF FA762K (.30 cal) and I used it on a number of AR15s. Eventually I bought a SF 556-212 and a SF 556 MINI ... they all will mount on the same .223 muzzle devices. The FA762K and the FA556-212 sound about the same to me (neither are hearing safe on an AR15, of course). The 556 MINI is louder than both.

Short answer is no. Accuracy is normally a little(very little) better w/a can on vs off no matter the cal, unless your hand loads are at max, or max +. A can added to that setup may push pressures over the edge to where groups start to open up as soon as the can is installed or 2-5+ rds later, depending temp. This is why if your going to run a can, it's best to have the rifle and loads at max summer time temps, when working up a load. Then there is never an issue with pressure do to long summer time strings w/the can on.
Be sure if you have never shot a subsonic load or worked one up in your stick before, to shoot it w/o the can on first. If it groups (4moa and down) then add the can,.... Baffle strikes will not add to your first can ownership, experience.

Can confirm that a .30 can is very effective on .223. Have Scott my templar archangel on my AR and was very impressed with the results.

Thank you for this! I would probably just purchase some ammunition vs working up a sub load that I won't use much.

If doing subsonic loads, you're usually much better off developing your own as with a powder like Trail Boss as it is very easy and immensely cheaper than buying any unless we're talking about something like 300 blackout.

Even buying factory loaded subs, I'd test them w/o the can first. Like said above loading you own is much cheaper and the on target results are far, far, better. I did Trail boss for awhile but went back to 700X I'd used long ago. Clays does a good job as well, but the biggest thing is the bullet. I'm stuck on a Lyman 180gr semi pointed cast w/a Hornady gas check, and won't change until something better comes along. To 4-500 yds I have not found anything that will surpass them, yet. I shoot them from a 12 twist and have not found a range I can't get to with all the up knob has and all the retical has to offer, that they won't be nose on upon arrival.

Add,... having one gun do it all is much to my liking. There are comps where you have to shoot specials, and the rules say what you start with, you have to carry to the end of the match. I'm old and learned long ago lite is right, plus you only have to know one stick. A dedicated sub stick is great, but sometimes you have to reach a little farther, to me it's all about trade off,....
