I would take my .338 SS Classic M70 in a McMillan stock with a 2.5-8x36 Leupy and iron sights. Cut to 23" it is a bit over 8#.
It is well below MOA with 5 loads that I have for it.
Load would be the old 225 TBBC HE load. I have lots.
Sort of a mid range setup but that is my choice.
I am sighted in 3.0 in high at 100 yards at the moment. I have shot it a lot out to 300. We have a 1000 yard range but I have only shot it out to 600. For the described range I might go up to 3.5 in at 100 yards and verify the new zero and drops to 600.
I prefer getting closer to shooting further for the heck of it.
A monster bull would be a thrill but only if I got to hunt for it.
