Sighting in back up sights

[JMEL]

Just a general question. What's the best distance to sight my back up sights to? 25 yrds., 50 yrds, ?? What have you gone done.

I recommend you check out the sticky at the top of this forum on "zeroes and trajectories"...good stuff there.

I use the 50 zero for everything. No reason to have to rethink new zeroes in the event you actually need BUIS.

Thanks for pointing that out. I saw that but thought it was for different loads and such.

I was leaning toward 50yrds as kind of a happy medium. With my eyes I figured any farther would be a waste of time.

Given you're a) shooting standard .mil ammo and b) have a 16" barrel, a 50-yard zero will also give you a 225-yard zero.

I acquired this chart a while ago from M4C. Positive numbers indicate inches above POA, negative numbers indicate inches below POA. I use the "16inch" column and have had pretty accurate results from my 16" carbine with Federal M193 (NATO) ammo.

To answer that yes and yes. That's a great little chart and one I will save. Thanks a ton for that.

It's really a personal thing to which distance we zero our irons to. For me, I like 100 meter zero.

Very cool info, just what I have been looking for, thanks!

The important thing the the 50 zero is knowing your 25 and 100 poi.

I like ballistics programs like iSnipe (for iPhone) or the many such programs on the interweb. Then you can enter your own ammo, your own height-over-bore, and your own muzzle velocity and chart or graph your own trajectory info. iSnipe is free IIRC.

iSnipe is definitely not free. $8.99 from the app store.

Hmac, have you used the latest version? Would you recommend it at that price?

You're right...my mistake. I don't recall what I paid for it last spring.

It's not a program I use that much since I don't handload and pretty much use the same ammo brands all the time (other than shooting range issue and surplus for destruction). It accommodates far more information than I care to provide or need (wind, temp, humidity, elevation etc). I use it to help visualize trajectories when sighting in my rifles, but my shooting isn't ever for groups, it's for 8-inch gongs.

The new version looks nice, but again lots of stuff I don't need. I'd pay the $8.99 just to be able to have it with me at the range in case I need it, but otherwise I think a simple calculator such as is free at http://www.handloads.com/calc/ works really well for my simple needs.
