A few comments… I have tried 2 new STO’s on different rifles. In both cases, they were probably the quietest (by a very small margin and barely noticeable), but in both cases they clipped when other heavier models didn’t. I was perfectly happier using the more accurate moderators that were slightly louder. Both were FX rifles, Impact and Crown. I wont bother again. I don’t think you are going to get magic quiet. With all the moderators I’ve tried on rifles, I have never been blown away by how much quieter one was vs another.
Thanks!I know that this is apples to oranges , but , I had one on a RAW HM 1000 in .25 cal . It was shooting about the same energy as your FX. I found it to be quite effective , and did not notice any poi shift as I recall. The gun and the suppressor have since been sold. I guess what I'm saying is "I think so"
Of course with me , my advice is worth what you paid for it ! On another note , should it not be what you want , it should have a decent resale value.
Good luck.

I like the design of that moderator very much! I'm curious how you think it compares to the basic plume design, like the 2x8" one you designed for me back in November? This one clearly has more material inside it, which reduces expansion volume, but the baffling and resultant strength of the moderator look like they would be great . . . .MikeAllen,
Mackeral5 on this forum has quite an impressive collection of airgun moderators, including the STO Sarissa. He told me that his Sarrisa works very well. That it works better at higher power. That it makes PCPs with a stock shroud work better than other moderators of equivalent dimensions. So, based on this endorsement, getting a Sarrisa would not be a mistake. That said, I suggest you ask Mackeral5 to speak for himself.
Now, Mackeral5 also has a number of custom mufflers and inserts that I designed for him. Some work better than others; which brings me to a side-note: The usefulness of factory-made moderators as benchmarks. So, when you have your Sarrisa in hand, I would like you to compare one of my custom mufflers against it. I do not expect my 6.5 x 2" OD effort to match the Sarrisa, but to give it a run for its money, at a quarter of the price.
To facilitate such a comparison a .25 cal 6.5 x 2" muffler with a half 20 thread will be on its way to your shipping address, by the time you read this, free of charge. The only costs you are expected to incur are for your pellets and air
This cylindrical muffler was derived from the oval offset moderator I designed for the Huben pistol, shooting at over 60 FPE. And, it works very well in that application. The wall thickness is heaviest around the blast chamber; then steps down as the pressure drops towards the front, to keep the weight down.
Anyway, I would not dare suggest that you try my offering first, to see if it meets your needs, before your decide on the Sarrisa. I would rather you rank the two mufflers, taking into account the absolute performance, size, weight and cost. Then post your impressions or results on open forum.
I shall close my topic deviation with; I trust that your Sarrisa will live up to its reputation.
Note that the waffle pattern ribs were added to the OD of the smooth muffler version that is shown in section below:

I haven't yet purchased the STO and may well not. I keep looking and poking around and haven't yet had a chance to do the testing we have discussed. The 6.5x2 with the waffle pattern looks a lot like the blue one that hoteltwofive sent to me when he sent the other prints. He does very nice work!MikeAllen,

. I would like your opinion on the 2 x 6.5" moderator anyway. Thanks - I look forward to receiving it!Mike,
You are under no obligation to buy the Sarrisa
This 2 x 6.5" moderator is a new design. It is different internally to the one sent to you previously, despite similar external appearances.
Can you make something to make my wife quieter?Mike,
