I will be going to the range today to sight in an Aimpoint on an 18.5" build. I'm wondering what distance I should sight it in at.

I have the irons set up for a 100 yard zero, and will be able to use them to dial out to further ranges.

I do not intend to do any dialing on the aimpoint so I'd like to find a battle zero and keep it there. Maximum range I will use the Aimpoint for is probably 300 yards. Beyond that I will likely switch to irons. I guestimated the sight height as 2" above bore as it is mounted on an EBR rail. My options are:

25 yards, Very close to zero at 300, however up to 5" high for much of the range in between.
50 yards, POI very close to POA out to 200 yards. Quickly drops off after that
100 yards, Least distance where POI close to POA, however I am familiar with drops due to shooting many other rifles at this range
200 yards, About 1.5" high out to 200. After 200 it drops quickly

I'm thinking the 200 yard zero is looking the best so far. Has anyone done this and what worked for you?

For my AR's it's been a 200 and sometimes 300yd zero. I decided on these after hauling the range finder around lasering realistic distances I encounter daily which is a lot of countryside stuff too.

200yds is a good compromise.

I have my aimpoint T1 micro zeroed at 100yards. With a 4 MOA dot it diminishes my pinpoint accuracy the further out I go.

I saw that, but my eyes, as well as the forward location the aimpoint is mounted, does not allow me to distinguish between top/bottom/sides/etc. It's also a 2 MOA aimpoint.

what range can you zero at?

i like a 250 y zero that will score hits on all but small targets.

i had to settle for just shooting a bit high at 200 yards and that gave me a good battle zero.

I have run this calculation many times and I am pretty convinced that for a typical centerfire rifle cartridge, the number to remember is 225 yard zero. That will give about 2.5" high at midrange and out to 275 yards or so will still be less than 2.5" low.

+/- 2.5" is good enough to hit the vitals of something like a deer so you can hunt etc. from 0 to 275 yards without worrying about hold over/unders.

+1..... I was just day dreaming about this earlier this morning. Even a 200m would give a slight advantage over 200yds but I like the 225yd too.
