Depends on your definition of "long distance."
Out to about 500 yards, I can shoot a pretty light rifle Had a Kimber Mountain Ascent with a lightweight scope. Combo was under 7 pounds. Fine to about 500 yards.
Out to about 900, I want a heavier gun. Both of my long range hunting rifles are between 9 and 10 pounds with scope and rings.
Beyond 900, I use a really heavy rifle (15 pounds with scope and suppressor.) Never hunted at 900+, but if I were to do so, I'd want a really heavy gun.
