Ruger MK IV with Thunderbeast Login/Join

I just picked up my Thunderbeast yesterday after starting my process back in late November 2019.

I screwed it onto my Ruger Mark IV and loaded 5 rounds of subsonic ammo. CCI subsonic, I can't recall the bullet weight.

The first shot was beyond my expectations. SO QUIET! What a wonderful experience. My ears were complaining that I should have purchased a can YEARS ago.

Then I tried the second shot. No joy. The pistol didn't fully eject the spent case from the first round. No problem, work the action pull the trigger and happiness follows. Apparently the subsonic ammo just didn't have enough oomph to push the bolt all the way back.

So being new to this I am asking the collective here for help. What do you guys suggest?

Try various ammo to see what works. I have found that CCI quiet won't cycle my 22/45 with GM-22. Std velocity and heavy subsonic work great.

Thank you. I was hoping that might be the case.

I just returned from the range and discovered that I had a few rounds "tumble" and leave "keyholes" in my targets. Is this normal?

It all depends on the pistol / suppressor / ammunition combo.

My Beretta 87 and M&P-22 Compact will cycle 22LR Subsonic Aguilla when clean and lubed, but after about 100-150 rounds, they typically get gummed up enough that they'll stop cycling. Aguilla Standards pushes that out past 200 rounds typically and I haven't gone much past that. Same with my Ruger 10/22s and M&P-15/22 rifles. Clean and lubed, fine with Aguilla Subs and some others. That is with an original SiCo Sparrow and a HTA B22 shorty suppressor. I don't shoot rimfire through my larger suppressors, ever.

In general, unless I'm trying to impress someone with uber quietness, I use standards in the semi-auto pistols & rifles and save the subs for the bolt action rifles - which are REALLY quiet with subs - less than a pellet gun, typically.

Concerning the keyholing, that shouldn't happen and might just be a case of the bullets going slower and tearing the target instead of punching a hole through them - really depends on how your targets / paper is setup though - I've seen this tearing when paper is thick and not supported (ie, just a wood frame or clipped to a hanger, without a cardboard backer).

Rhino, thank you. What you were writing about key holing is probably true. I was looking at the targets more closely and was seeing what you described.

By chance are you running the "Quiet-22" from them, look at the box... that stuff is 710 fps, won't cycle a semi. The other subs that they make shouldn't be giving you a problem.

Candyman, yes you nailed it. In my fervor I grabbed what was close to me. I really should have asked more questions. (I maybe would hope that the guy behind the counter would have mentioned it to me...oh well. He's been good to me he probably thought I knew.)

Sigfreud, I'm going to give the targets another look. I don't have anything that looks like the middle (keyholed shot) but my targets do resemble some of the others shots in your picture.

Thanks for the help guys. Being new to the suppressed shooting arena has opened a new can of worms and I am excited to learn!

If it makes you feel any better, you won't be the first or last person to experience that. CCI should really label the box "for bolt action only". That stuff is stupid quiet as you've experienced! Federal makes some subs that are pretty good as well, the best stuff is the Gemtech stuff. A little bit pricier then some, but constantly quiet and accurate...

Thunder beast advertises 112-114 db and Silencerco Sparrow advertises 41db sound reduction. Excuse my ignorance, but which would be quieter. Full disclosure, I have the Sparrow and while it is quiet I wonder is something else is a better suppressor.

I didn't read the instructions! Ha!

You think I would have learned by now.

How long is your barrel? Many standard velocity .22 LR won't become supersonic in a pistol barrel. Try various brands out and you may find a load that's full power to cycle the action and still remains subsonic out of your pistol without the need for the extra expense or difficulty finding subsonic ammo. I just run normal .22LR and can't tell much difference versus subs.





115 + 115 = 230

It has a 4.25" barrel. That's an excellent point M4. I was pleased with the regular 22LR ammo noise reduction it is just that those subs were a whole 'other level of quiet.

I am going to try some different ammo I recently had come in.

Realize that those are extreme subsonics (22 Quiets). Regular subs run around 1000-1025 FPS and typically work great in semis, but as mentioned standards rated at 1130 FPS are typically still subsonic out of a pistol barrel. Even normal 'high velocity' is sometimes subsonic out of a pistol, but it will be louder.

Now on a rifle, you will typically get the 'crack' from standards and always with high velocity 22s. Still very hearing safe but not 'quiet' and definitely sounds like a gunshot, if you are trying to not garner attention. Wink

For general plinking I’ve found that CCI Standard Velocity (SV) to be the best bang for the buck. Stays subsonic out of 16” barrels and will cycle semi autos without issue. I also have a sizeable supply of Gemtech subs, but have found their accuracy out of my CZ 455 to be less than stellar, but they are quiet. Even worse than the Gemtech are the Winchester Suppressor subs, horrible accuracy. American Eagle Suppressor subs are decent though more expensive and harder to find in quantity than CCI SV.

Rhino, I did not realize that. Thank you.

I am spending my lunch tomorrow with several different kinds of .22LR and I'm looking forward to coming back here to write it up!

SigM4 I have some CCI SV to try out. 40gr stuff I think. I am anxious to learn what works best with my combo.

Rhino, I never seek attention. Big Grin

I was told by a silencer dealer that the minimum of 1000 fps is required to make a semi auto rimfire function properly. Anything less should be reserved for bolt action rifles.

That’s probably a pretty safe generalization. I have some ammo that comes in around 950 or so that will function semis with an issue, but it’s a 45gr I believe. The heavier bullet may make up for the reduced velocity.

My favorite suppressed ammo is the Federal American Eagle 22 suppressor , copper plated and 900ish FPS. Hard to get during these times sadly.
