It is interesting ( and somewhat amusing) to observe the 
emotional reaction some on this forum have to suppressors. It's something you don't really see in parts of the world where suppressors have been in use for multiple decades. Carl S will identify with that. I guess change is unsettling to some people. Here in NZ, no-one cares whether you have a suppressor or not, it's entirely up to you and they're as easy to get as a recoil pad. Definitely don't have the Govt clipping the ticket and sticking their nose in.
All of my sporters and varmint rifles have suppressors, the exception being my heavy .280AI deer truck gun with  27" bbl. None of my competition guns have them as there's no point. One of the big advantages of suppressed guns is when you're out in the field with buddies- you don't have to worry about blasting them. Far more sociable. You can shoot a deer on one side of hill then find another undisturbed one just over the crest.
Much of the velocity loss with shortening barrels can be overcome with intelligent loading.
Here is my 7-08 Tikka with a 16" bbl. It deliver a 120TTSX (equivalent to a 140 lead bullet) at 2940 and that thing kills deer very well out to 300yds, further at times. It is very light and useable in tight bush, something we have plenty of here.
