I'm using it right now. I do think it is a little louder than the other subsonic loads I've done though. I fired some mixed w/ my VV320 load and it was noticeably louder. But I don't care. To me it was only slightly so and VV is too hard for me to get on a regular basis. I also think the Bullseye load is quieter than the Titegroup but I think the Titegroup burns cleaner than Bullseye.
