This is why it may also be necessary to change buffers when shooting suppressed. For example, my 11.5" would cycle 100% using an H2 buffer, but I would not get 100% magazine lockback everytime. Once I went to an H3 buffer the problem was solved.
The baffles work by slowing down and traping the gases before they leave the barrel as well as allowing it to cool.

I would say your post is mostly correct, but I must disagree with the mention of a lower MV. Where have you seen or tested this?
If there is a change, it is usually a slight increase.
Whilst the post is still about suppressors, a quick photo from a test shooting / zeroing session today. Range 100 meters with Lapua 167 gr Scenar
