I have all three lengths of Ultra. The 5 lives on a Tikka in 308, cut to 16". It isnt linearly louder than the 7 from the 9, at all. Use one before you buy, for sure. The 9 is amazing, the 7 is great. Comparatively, the 5 sucks. I like mine for the light and handy 308, don't get me wrong. But it may not be what you think it is.
You did yourself well with this question and all the responses. Good thread, gents.
