at the moment I have a .243 I use for all of my deer stalking, I am thinking about buying a new deer rifle in a bigger calibre then getting a ,223 for my fox shooting rather than having one rifle for everything. my .243 is so quiet with a mod on, I want to get the same level of noise but with a bigger calibre. I would like something like a .270 or .308 possibly a 7mm-08 but want something as quiet as possible whilst still being reasonably flat, if I went for the .308 I would use the 123g bullets. I would just like to hear from those who have two of the calibres I mentioned and see if they notice much difference between the noise. thanks all.
