Stupid question of the day????

Riddle me this:
If a moderator manufacturer recommends that you buy their moderators one size larger than the caliber of your gun, .......Then why do they even make a .177 cal moderator?

My low power stuff uses 177 specific mods a lot better than my high power 177. Low I mean 12 fpe or lower. Granted they are not loud to begin with and a 22 cal mod would do fine, but it’s nice to go ultra quiet.

My Revere 18 fpe and Bullshark 22 fpe both prefer 22 cal mods. Grouping is better.

With high power you get more air typically after the pellet and the extra space in a 22 cal mod helps it dissipate better. The lower power 177’s don’t have a lot of extra air.

They recommend one size larger because they don’t trust the machining on guys guns. If a high powered .22+ clips the mod, destruction can occur. With a little .177 and the mods internals still being what they are in the larger calibers, they can handle some clipping if the guns tolerances aren’t what they should be.

It's important to make sure the moderator IS what you think it is(disassemble and examine/measure internals, measure exit holes, weigh it, etc...). Moderator companies may change specs, materials, internals, etc... over time and they may or may not give notice or this change. This means that the ".22 XYZ brand" moderator that you just bought sounds/performs differently than the "exact same" model moderator you bought a couple of years ago. It may explain why some people report different experiences using "the same" moderator on the same gun(at similar power levels) also.

Yikes!

I’ll be darned, now those calipers are coming out. Trust but verify as they say…

If you buy quality guns and quality mods, there will be no reason to use a mod that is oversized. It's really that simple.

But if you have to, it's simple to do. I fitted a brass sleeve to my Huma.
