    I'm curious at white height do most of you sight in the 6.5 Creedmoor.

    I normally set my rifles to be 3 inches high at 100 yards, for a test, I sighted in my 6.5 CR to be 5 inches high.

    Not a good idea, since it's shooting over seven inches high at 200 yards no.

    What works for you?

    I sight mine in dead on at 100 and time permitting dial all my shots. If I want to use a max point blank range, I’ll dial in .8 mils which gets me out to about 310 yards on an 8” vital zone.

    Dead on at 100 and dial as needed on all rigs.

    This might seem a little silly, but I guess I need to start using the dials on these expensive scopes I buy.

    Honestly, I've always been a dead aim guy.

    Learn how to use your dials and you will blow your own mind...

    Visit jbmballistics.com and plug in your load information and environmental conditions, it will show you drops in moa or mil and you can work on a drop chart. Drops aren't bad, learning wind holds is never ending for me.

    Dead on at 100 or 200. All of that high here and low there is back for when scopes did not track good.

    I zero all mine at 200 dead on. Depending on cartridge/bullet combo, that is anywhere from .8" to 1.5" high at 100.
    Build a drop chart and dial elevation. Only time I holdover is when time does not permit dialing. Range, check drop chart, hold over in MILs, not inches.

    all my scopes are FFP moar so I set zero at 100 and use my sub-tensions while hunting and use the turret when target shooting:)

    I try to work out each of my hunting rifles for a sweet spot that lets me shoot dead on from like 0-300 yards. It changes for each caliber. Target only rifles are zeroed at 100
    and I make a little card for those.

    5" at 100 will give you about a 400 YARD ZERO...give or take roughly .6 of an inch. Zero your gun at the distance you want zero...if you don't have access to that distance then a ballistic calculator will tell you based and load and speed. That being said...if you are trying for at 200 yrd zero about 2.4" would be closer

    For decades I employed the old 3" high at 100 yards sight-in method. This was the max point-blank range concept, and it revolved around the six-inch circle that somebody once wrote about as being the size of a deer's vitals. The max PBR for most of the cartridges we used was in the neighborhood of 225 to 250 yards, and this was all fine & dandy.

    Now, when anyone still uses this sight-in method, the magic number seems to be 2.5" high at 100 ( as cited above ) and I think this came to be around the time we started seeing all the plastic-tipped bullets come on the market. BC's were improving, so the trajectories were flattening a bit. This trend has continued to the point where the whole max PBR concept is falling into dis-use, and more guys are now dialing their scopes for long range shooting. The definition of the term "long-range" has changed pretty dramatically in recent years, as well.

    Another thing that has changed this is the increase in the use of range finders among hunters. It used to be that guys would get a "flat-shooting" cartridge, sight in 3" high, and figure out at what range a top-of-the-back hold would still kill the animal. Then they would call that their maximum range. If the animal looked pretty far away, they would try that hold and see what happens - if they shot under, then they figure it was too far.

    Things were far simpler then, but but simpler isn't always better. With the bullets we have now, the old concept works better than it has ever worked in the past - but it still doesn' work better than what most guys are doing now.
