Title: Sighting in my rifle
Post by: TrainWreck on February 07, 2014, 01:32:37 PM
Well, I'd like to get my rifle sighted in now that I have the Tech Sights installed but there doesn't seem to be any place for me to test it out at 25 meters. ::) I have an indoor range that is 50 feet that I can sight it in at but that is a far cry from the roughly 82.021 feet (25 meters) that is required.

Anyone know how high the impact should be on the target from point of aim to be properly sighted in at 50 feet? ???

Thanks to anyone that may be able to help.

Using my handy dandy "Strelok" ballistics calculator I find that in my 10/22 using CCI Blazer ammo I will be 2.66 MOA high at 15 yards when zeroed for 25 yds.
So zero at 50 feet and adjust 2.5 minutes (good enough without all details of your rifle/ammo).

:-[ Please excuse my ignorance here.......are you saying that at 50 feet the impact should be roughly 2.5 inches above my point of aim? This is all new to me. I apparently have way to much to learn. :(

Zero at 50ft. You'll be plenty close enough for the event.

You'll learn the rest there.

2.5 MOA is only 2.5 inches @ 100 yds.
@ 50 feet 2.5 MOA is just over .41 inches.
So as usual, slim is correct. Zero @ 50 feet and you will be good to go.
Sorry for jumping ahead this is well covered in IMC at the shoot.

What Slim said.  It will be close enough and it will put you ahead of 90% of the other shooters.

And, you will be easily "on paper" at 25 meters. You'll be more than "close enough" to zeroed.

Over the course of the weekend, your zero is very likely to change some, as you learn to shoot a little differently than right now. The differences usually affect zero slightly.
