"I was at the range today and found I couldn't shoot at 100 yards with 9X zoom. Drove me crazy that that I could never get the reticle to sit totally still on the bulls eye. I had to lower it to about 5 and my shooting improved significantly. IF I was shooting a target moving at all I would probably drop it back to three. The 9x was GREAT for checking my target though. Almost worth the extra money I paid."
There you go. Being able to "check targets" is the only advantage to high magnification, at least at moderate distances.
"This is true as you state- The movments are there even if you can't see them as well so that is a null statement. The closer view ( in target shooting) is a very big advantage to have. I will keep your groups much tighter than low magnifaction. As you state for hunting a 3-9 power is all you need unless you go after those little dogs at 600 yards"
Hardly a null statement. The "shakes" ARE magnified....the higher the magnification, the worse it gets..... and the MORE difficult it is to shoot accurately. Just having a close view of the target face does NOTHING for accuracy. It may "feel good"....because you can see the grain of the paper....but that doesn't equal accuracy. Accuracy is about replication.... doing the same things, the same way, for each shot. High magnification is useful (and needed) for truly long range shooting, yes. For targets at 1000 yards, for example, of course one needs high magnification. But it is a handicap at moderate distances. The lowest magnification one can use to shoot accurately, at a given distance, the better....period. That WILL vary somewhat with the individual. But, for example, using 9X, where 4X will do....will NEVER make for more accurate shooting.
If one is blind and NEEDS 9X to shoot targets at 100 yards....well, that is a different matter.
This concept, that being able to see the grain of the paper, or count the hairs on the side of the deer you are about to shoot... somehow makes for better shooting.....is nonsense. It is a fallacy - a "hole" - that many fall into. It ain't so. If you don't believe it, then run some tests on this yourself. If you are honest with the results, you'll see.
