Been smoking deer with a old 243 Rem 788 carbine with a 4x Bushnell for 30+years.
I'd say 90+ % of the shots are sub 150 yd. one shot kills.
I love the way the industry is telling everyone that you need a carbon 6 lb gun with a 6-24x scope with a magnum 6.5/6.8 mm
That saying, a carbon 6 lb 6.5/6.8mm mag gun with a 6-24x scope sure is pretty.
