Honestly the 155 Scenar pushed by stout loads of Varget does so well that I really don't bother with much else.
Between the .223, .308 and .300 Win, all my centerfire needs are easily met.
The older I get, the less I want to fiddle with a bunch of different cartridges. Time is limited, and I would rather be in the field shooting/hunting than dinking around with load development and such.
