Suppressed 6mm ARC & or 6.5 Grendel

If I didn't already have one I'd get the Harvester Evo. It's even lower now than what I paid. Quite satisfied with it on my .308, 6.5x284 and 6.5 CM. Waiting to get my 6CM threaded so I can use it there too. Only got 1 good ear and trying to save that one. https://www.capitolarmory.com/silencerco-harvester-evo-rifle-suppressor-7-62.html

The EVO (.30 cal) is what I'm running on a 20" CMMG 6 ARC and it's been great so far, cases eject at 3 O'clock as supposed to 430 unsuppressed. An adjustable gas block could correct that but so far so good how it is.

Looking to purchase my 1st Suppresser. Majority of my shooting in the last 3 years has been done with a bolt action 6mm ARC. Prior to the 6mm ARC the bolt action 6.5 Grendel was my preferred cartridge to reload, shoot & hunt with.

Suppose I would like to hear from those with experience with suppressing these cartridges with a smaller powder column. Care to offer your experience & recommendations?

Rugged Razor or Q Thunder Chicken suit smaller powder columns well.

Real talk. Find the biggest dealer of cans in a few hours drive. Call them up. Ask how much to do a demo or go to their next demo. Expect to pay a few hundred. This education is money well spent.

Bring your threaded guns and factory ammo.

Then go try some stuff and learn.

If you don't hunt inside--doing a demo on an indoor range is pointless.

Don't hesitate to call a few big places. A lot of dealers selling suppressors don't shoot hardly at all. You will find one who will. Might not be the first one you call.

Years ago I bought a multi caliber can from Liberty (its the Mystic model). I've used it from 17 caliber up to 308 on handguns and long guns. I'd go with something you can use on multiple guns unless you plan on buying multiple cans.

I'm running a YHM Resonator "R2" on my 6.5 Grendel with 2 different loads:

1) 90gr Speer TNT/31.5gr 8208 XBR
2) 120gr Sierra Pro Hunter/27.7gr H4895

Have no complaints whatsoever.

If you were going to go 6mmARC and use on your 223... then I say Wolf Hunter from Diligent Defense, or the new 6mm that Otter Creek is coming out with.... otherwise, I'd say, go with the Enticer S from Diligent Defense or the Otter Creek Labs Polonium 30. With 30 cal cans, they will generally lose some suppression of sound with anything lesser than the 30 caliber it's intended for, however, the 6.5 Grendel and the 6.8SPC are intermediate in velocity and suppress quite well with both of these cans. I do not have an explanation, but Jay with Pew Science has discussed their signatures on the 308 to give a baseline of what to expect from them.

Both of those cans mentioned come with HUB compatibility and allow use of many different style of muzzle devices. I personally own the OCL P30 and shoot 6.8SPC and several grendel shooting friends have the Enticer S (along with several other cans), and choose the Enticer over their other 30 cal cans because of how well that the Grendel suppresses using the DD.
