Low power allows you to pick up your target faster. Better for close range. Also allows you to shoot with both eyes open. Faster target acquisition. Red dot type "scopes" are great if you don't need magnification.
I used to think scopes were overrated, but then my brother in law and I got into a group of mulies as the light was failing -- he had a scope on his rifle and I didn't. He got his deer, but I couldn't see the front blade reliably enough to take the shot. I've been a scope hunter ever since.
Of course, after a few years of that mentality I hunted whitetails in the woods of Alabama. My son and I jumped three whitetail that exploded out of the brush to our right and bounded off to our left just a few yards away. I snapped my rifle up, but all I saw was tree branches.
There's no solution that works every time. Sometimes you need both.
Accuracy. What an incredible way to give yourself a true advantage.
Go to your club and get a bunch of guys together - and put a target out there at 250 meters. Break out the deer rifles and see who can shoot a decent group, even off of the bench, at this distance. I think you will be shocked at how few can do it.
So - with that in mind, I recently set out to try to develop a semi-custom rifle that I could afford and that would shoot - repeatedly - at MOA.
I started with a platform that I love...
