I've been thinking of trying a modular moderator such as the Ryu or Yokozuna
or maybe a impulse air 1350 -1200.
my question is why they would recommend a 30 Cal mod for a 25 Cal?
i had thought they were sized to caliber to keep quiet or maybe because I'm shooting 30-34g slugs.
also recommend i buy a couple extra baffles which makes sense for tuning purposes.
i have no issue with the factory hollow can that came with it its quiet and shoots well.
i was just thinking maybe with a modular you could tune better by adding or taking away baffles.
but i had also thought to stay correct to caliber due to it will be a louder bark? not sure 100%
what's your thought?
 
It's the price you pay for modularity. There's tolerance stack up at play. To get it really precise, with a lot of pieces in the part, would cost a lot, so instead, they open up the hole to prevent baffle strike. So you get a little more noise, a reasonable cost, and a modular set up. Really, it's about economics. Every screw joint has a tolerance or position slop to it. You can make a better fit, but it costs more to make.

The .05 difference between using a .30 mod on a .25 gun will make little to no discernable difference in sound dampening quality. It's always nice to have that .05 extra clearance to even further avoid clipping if trying new & untested ammo in a gun.

Agreed , I have all .25 caliber for my .22 guns, as suggested by UA Guns long ago. I have .25 & .30 Buck Rail moderators & no noise difference that I could tell.

here's my experience with a modular moderator on the issue:

Airgun Technologies - Vulcan 3 HP .30 with added Huma MOD40-4/0 = severe clipping!

I recently got a Vulcan 3 HP .30 and had severe problems with slug clipping when i attached a brand new Huma MOD40-4/0. Since the moderator is modular, i was able to try different configurations, from several meters in POI shift all baffles to a less than 10cm shift of POI on 50m with two...

Good to know as I bought a Vulcan 3 30cal awaiting its arrival.

I own the YOKOZUNA for the .308 Texan and am very satisfied with it. When operating within factory specifications, it is exceptionally quiet. However, when going outside from those specifications, it produces a slightly muffled bark. I appreciate that it serves as an additional tool for tuning my PCP. opted for the spring-loaded version.
