Parallax error

[Hard2hurt223]

I don't know a ton about the subject all I know is that it made my shooting much more consistent and my groups half the size but mark and sam after work is where I found the video titled parallax (for a better group) and what I learned is amazing maybe I sound stupid because this is shooting 101 but I've never heard of parallax error until now and I'm blown away by how much of a difference it makes these are 2 of my 5 shot groups from earlier today at 100 yds

many people do not know this i know guys that hunt deer and such an don't know about it and dont want to know , they just point and shoot .

sadly, thats how everyone i know is too lol

they are missing out

Any sighting method that doesn't involve lining up two bits on the rifle will involve addressing parallax. Made a world of difference when I discovered that I had to adjust for it. All of a sudden my scope accuracy improved, who woulda thunk it...

One reason for the popularity of reflex sights (so called red dot) is that parallax error is greatly reduced.

The other advantage of an adjustable parallax is it makes cheek placement less critical.

Parallax needs to be adjusted for the distance we are shooting when we are target shooting or hunting small animals. But for hunting deer, where the kill zone is larger than a small animal, it is not as critical. So there is a difference my 30-06 does not have adjustable parallax but all my airguns do.

I think the first step is to adjust the diopter lens so that the reticle is clear AND when you shift your head position on the stock, your point of aim does not shift. When you cannot change your point of aim with your head position you will have the reticle in focus. After you get that adjustment made, then dialing in the parallax should occur. You do not want to do it the other way around because the diopter setting will change the parallax setting you need. It isn't totally just the distance to the target that determines the "right" parallax setting. This may be one reason some scope manufacturers don't label the parallax settings.

This is why I was taught to find your cheek weld and keep it when I was a kid sighting through a scope. The error can be minimized without parallax correction from the scope if those principles are adhered to always. But if you have more than one rifle and don't shoot them often the parallax correction on an optic makes things much easier.

UNLESS the future jerked venison is 1,000 yards then....it's important. Hmmmm, I was taught to focus the reticle with the diopter using a blank white sheet of paper out a bit 20 yards or so, get it nice and crisp, THEN you do your parallax from that point on. If you move your head your crosshair/dot should remain exactly the same place.

I’m working with a friend to develop a load for his new hunting rifle. I’ve been letting him shoot as many of the load dev rounds as he wants which has been almost all of them. Last week he shot most of a 20 shot ladder and when I shot the last four I noticed outrageous parallax error. 1-2moa when I moved my eye around. So everything was wasted. Try again this weekend I guess they’re his $0.70 bullets.

Another reason for why I use red dots that is technically not parallax related - removing sight alignment error caused by poor eyesight!

Back in 1982 I used to be able to hit the 100 yard IHMSA 22 Cal Ram target every time with my open sighted silhouette rimfire pistols from the Creedmoor position. Today, I am lucky to hit 4 out of 10. Put a good quality red dot sight on there and I am back to 100% again! My 10 shot groups with 3" barreled handguns at 25 yards using iron sights that I used to take for granted back then, have now increased at least 4 fold. Again, bring in the red dot sight and it is 1982 again! Those tiny marvels have made offhand shooting fun again and they allow me to have a super compact, lightweight and fast handling setup in a handgun or rifle that I can get very close to scoped accuracy out to 100 yards.

---------------------

I want parallax adjustment on every scope I own - even the 1-6x or 3x fixed powers! I had to chuckle when helping a young friend try to shoot his rifle at 25 yards with a fairly expensive 1-8x optic sans parallax adjustment. He kept trying to focus the target image with the reticle focus, saying things like "Why isn't this in focus!" and "There must be something wrong with my new scope!"

Red dots still have parallax effect up close. I use the Hawke Vantage. They have the closest range parallax free specs of any red dot that I've checked. 30 feet and further is parallax free with the Hawke. Others I checked are 50-75 feet and further out parallax free.

gotta check it a must
