Hi,
Thanks! I really put a lot of effort into this video, propably more than to any other video I have done

I noticed myself that pretty much anything you put into the barrel will change POI. It does not change the POI a lot but even the slightest will change how you hit at a 100yards.
My Hatsan Flash .22 shoots 25gr pellets at about 890fps with the tune and the 18gr go at around 970. The mods propably do around the same DB reduction on the same % difference on the sound moderation from the "base" level. This is what I would imagine it doing.
I wanted to do the test with a same pellet and a pellet that I knew is performing well on the barrel. Also I measured the DB on a 90 degree angle from the same distance from the muzzle. I felt that this was pretty accurate way of measuring the noise levels. I have some professional experience on sampling and testing (from other industry fields) so I felt pretty good with it.
One thing to note on the Wolf Airguns moderator is that it is significantly bigger in size, but has different "pitch" on the sound. The pitch is higher tone and more noticeable to ear than the other mods have. I suspect that this is due to the way to moderator is built. When I disassembled the other moderators I saw that they others had felt on the expansion chamber. Because the Wolf Airgun moderator is enclosed I would assume that it does not have felt on the expansion chamber. This is also to be taken into consideration if you want to clean the moderator, you might need to have it on ultrasonic to get it cleaned after shooting a few years with it. Although I have not cleaned my DonnyFL ever and it has around 4k rounds on it now
I am thinking of doing another review for the best sub 200$ moderator. If people want to loan their moderators please let me know

I dont want to buy all of them xD
