What magnification ????

There are lots of different answers to that question, here's mine: most of my guns are zeroed at 30 yards or 50 yards. The ones that are zeroed for 30 yards I use 12x for stuff out to 75 yards, but there aren't enough mildots at 12x to get on target so I dial DOWN the magnification to 8x so I can use the reticle to get on target. I will only take a shot like that if I'm plinking or if there's absolutely no wind. The gun that's zeroed at 50 yards I shoot at 16x.
Hope that helps.
PS-when shooting offhand I dial down to 4x
 
Hi everyone, I have to tell you my experience (first time shooter) because I never considered there to be a problem zooming in and out with a scope and shooting your target. Well call me stupid but when I figured out that you can't do that and hit your target I soon realized you pick your magnification and shoot at that setting to get your shot curve and it is repeatable. Clearly I was unaware and I don't even know what I did because I was all happy to get my first pcp rifle and go shoot a paper target then set out cans here and there and started zooming and shooting and mostly not hitting anything. I can't explain it but I know the magnification changes your point of entry. I hope someone else did this and I'm not the only one that didn't know how a scope worked. Any way it's a year later now and I use mill dots at one magnification setting. So what I have is a FX T12 400 in .25 cal and I upgraded my scope with a 8-32x56 Hawke and what I found was setting the scope on 18 power I could shoot from ten to one hundred yards using hold under and hold over. I want to shoot out farther like Ted's HoldOver on You Tube but haven't yet. I run out of mil dots and I know that less magnification will give me more room for mil dots but the image is so small at a hundred yards I wouldn't be able to hit it with any precision. Zeroing in at a farther distance will do the trick but then I lose the close shooting so I have to figure that out. Now zooming out to one hundred yards at thirty two power looks great but I can't sight it with out raising the back of the scope and that changes everything again. Hopefully this will make some of you laugh with my learning curve but I can tell you that I can hit a squirrels head out to seventy yards and eighty ninety and a hundred yards is harder to do especially in breezy gusty windy conditions so all of those shots are not taken at this time but when I get better at it they will be fair game too. Oh, I don't shoot off hand at all, I need a rest of some kind and I love the quietness of an air rifle.
