Re: How much magnification do you really need?
Most people use their scope in more than one specific application.
For example, I use my scope in load development where my rifle is clamped tightly to a vice on a bench. The high mag allows me to aim very precisely to an exact spot reproducibly and with 32x, I don’t even need a sighting scope to tell me where the rounds are hitting. If you cannot tell exactly where you are aiming, how are you going to ensure where you are aiming when trying to assess if a load is sub-MOA (that is a group with a diameter less than an inch)?
At the 600 yards range when I shoot my OBR, I shoot F-class so I have both a bipod up front and a bag at the rear, so heart beat is not a huge issue, so again with the 32x, I know I am aiming at the X and not somewhere around there….
When I shoot my 20” stealth at 600 with only the bipod, it is more challenging but frankly compared to off hand at 100 yards, the little wiggle due to heart beat is nothing. If it gets too difficult because one finds it hard to control the POA, or the mirage gets too much, you can always dial back. Mine goes down to 8x but I have never used it there.
The key is unless you are shooting at something really close, that 8X is going to be more than low enough but the 8-32x range will cover your needs. If you buy something like 2.5-10x (which I have), you don’t have that option if you shoot in the above situations.
I am not saying the 8-32x is right for everyone, but the trick here is knowing what your applications are before you buy your scope and make your decision accordingly.
