I have the 5" 30 cal.
I shot it against the 4" and it was substantially quieter on both a .270 and a 6mm ARC. Have not tried on 300 WSM yet but assume it'll be fine.
The 5" is certainly not an "ears-off" practice can. However I find I generally shoot with ears anyway during practice, so the difference is academic. The weight savings, however, are far more than academic.
It's a specialized tool, but it does what it does better than anything else. For 1 or 2 shots outdoors hunting, it will save your ears if you are the type of hunter who would otherwise hunt unsuppressed without ears. I did not come away from the 4" convinced it would actually save my ears in that same way, and the incremental length/weight seemed worth it to me to accomplish a goal.
Hope this helps,
