Will a .243 take a big deer reliably? I am in very wooded N. MN, hunt on foot and most all shots are <150 yards on moving deer. Taken a number of 225# dressed Whitetails with shoulder shots. I ask because I have a sweetheart of a Sako in .243 Win that I would like to use some. Thanks.
In the right spot, yes. Big calibers /bullets in not the right spot isn't going to help much.
This.
A 270 Win is more than enough for antelope, but when I was guiding a lot I saw a guy hit an antelope six+ times with a 270 and the animal didn't go down. It was literally dragging a leg and it's guts across the ground.
On the other hand, all of the antelope I've seen hit in the chest with a 243 went straight down.
Where you hit them is the most important thing. The design of the bullet is the next most important thing. Everything else is a
very distant third. Few understand this.
