All things being equal (same can etc) will there be a significant difference in sound between a subsonic 308Win or 300 BO? I have experienced some powders that are louder in some loads; specifically AA5744. It's dirty, leaves unburnt kernels, and has a noticeable 'pop'.

I want to add a CVA scout to the safe for a compact, fairly light package that breaks down. That little 16.5 inch CVA is enticing for fun, but the 20 inch 350L would be a more practical caliber for me I already have good rifles and subsonic loads for 308 Win and 350L. So if the 300 BO isn't going to be a significant improvement of the 308 I'll just get another 350L.

Thanks.
