I like mine.
I have owned a few 6.5s in my life, but I am down to just one, and I like it better then all the others

Not because of the cartridge as much as the rifle it's in.
I have had one 260, one 264 Win mag, two 6.5 Swedes and one 6.5 Grendel but I like my 6.5X56 M/S more then the others. Not because of the cartridge as much as the rifle it's in. But the 160 grain RN bullet starting at 2330 FPS is killing everything I have shot with one round each.

It's a lot of fun to hunt with and gives me a feeling of accomplishment when I take game with it, which I have done now ......several times.
Here is one I got just a few years back.
