I love the 6.5x55!

I've owned one for almost thirty years, and many other calibers have come and gone, but this remains my favourite deer rifle chambering. My best ever shot on game was with my first M96, almost as long ago, with Norma 140 factory ammo and the factory iron sights. It was as long a shot (sitting with a sling) as I had any business taking (and yes I had spent a lot of time on the range), and it was the most instantaneous drop I have ever seen. I know my 284 could have done the same,but no better. What more could you want? The 6.5 is more pleasant to shot than the 284, and I personally believe the 6.5 can do anything a .270 or 7mm non-magnum will do if you load it right.
If I ever decided to cut back to one chambering (and I can currently choose between more than

a dozen), this would be it!
