I suppose only the more expensive 'red dot' sights have an adjustable dot size? I played with a cheap one a couple of years ago and the 3 or4 moa dot did show on target without a doubt, but was too big for me to get comfortable with. Seemed like at 25-50yd on a deer it would cover a lot of deer. Now maybe thats just disconcerting to my eye/brain connection, moreso than performance in the field, but it doesnt instill confidence in my equipment, which I need.
Ive learned too, through the years, that in trying to scope early morning deer, if I cant see the crosshairs on a traditional scope, its too early for me to be pulling a trigger. Thats OK, I can wait.
On a .44Mag, etc. I would prefer a lower power scope than that 8X, like a 2.5 to 4X max., so unless you have another rifle and caliber better suited to that 8X, it likely wont be the scope you end up with on the 44.
