New To Air Rifle - Pellet - Glasses Questions

shadow · Post by **shadow** » Sat Sep 21, 2013 7:48 pm

I have shot air pistol for years. I recently acquired an PCP air rifle. Do air rifles use the same pellets as air pistols or are they heavier?

Also, I am farsighted. I have Champion prescription glass for AP but everything was blurred when I tried them for AP,Is an entirely different prescription required?

Thanks for all of your help!

Pellets labeled "Rifle" are heavier than those labeled "Pistol". In real life, it doesn't matter which you use.

Prescription for rifle is usually 0.25 diopters less than for pistol. For rifle you want to take your distance vision prescription, and add +0.50 diopters.

Depending on the degree of farsightedness, you can experiment with powers in reading glasses. These are usually available from 1 to 3 diopters.

Also, if you have round Champion lenses, I can cut a new prescription for $40 per lens using AR coated polycarbonate.

My rifle and pistol glasses are exactly the same prescription which makes sense because the foresight of both when on aim are at a very similar distance from the eye, and its the foresight that the prescription should be set to. That said you may find that in reality you need a different prescription, but you can only find that out by trying it. I took my AP to the opticians but I decided best not to for my small bore rifle, but the same prescription works well in practice.

If you have the money you can buy an expensive rear sight iris that Gehmann made that essentially has all the functions of a shooting glass and more. In that way you do not even need to wear your prescription glasses.
It costs a fortune, but since everything is adjustable on the fly, you will never need to buy another lens or filters again. I would recommend it if you plan to be serious in AR and consider as a long term investment. The iris system you can keep and simply mounted on a kk gewehr, freigewehr, standard rifle, etc whenever you change rifle.

Finally, using the iris as a shooting glass is more comfortable than wearing shooting glasses and then look through the rear sight.

Except that a diotre/optik is not ISSF legal for 10m air, 50m smallbore, or 300m fullbore. Fine if you just want to shoot at home, but not if you have any thought of competing.

The diopter lens is not perfect. Have astigmatism? A prescription lens can be ground to correct for it, but the dioptre lens cannot.

Add to that because it's so small it has to be optically perfect for it to give you a clear sight picture. I'd much prefer a properly fitted glasses lens personally.

Conradin,

Did you go to Dr. Wong for your glasses yet? Or are you still sprayin' and prayin'?

Holding your mouth right doesn't always work.
