You can easily figure out the answers to all these questions with a little range time.

Personally, all of my rifles except rimfires are sighted in at 100 yards and I know exactly where they shoot at 200 yards and on out in 100 yard increments to the maximum practical distance for that particular setup. Could I get excited and miss a deer? Sure, but it won't be because I'm guessing at where to hold on him. It would just be because I made a bad shot. Happens every now and then, even when shooting targets.


Can't argue that.

What's the experts opinions?

roflmao That pretty well does it.
Or if you reload sight it in at 200 yards with regular ammo and then reload some ammo with half the powder for a perfect 100 yard zero. bolt
Hopefully everyone knows I am kidding and not try this, right? confused2

Set up with a load of the right velocity for a MRT of about 160 or so yards so that you're on at both 100 and 200 yards.

There.

If you answered the questions that were asking specifics, you'd get more straight answers.

Zero at 100 or 200?

Depends....

Dalee, all of us went thru a learning curve asking DA ??'s with at least some of them with self evident answers if you really thought the question thru.

So here's a couple thoughts to consider in answer to your initial question...there is no perfect answer, or any reasonalble answer until you can answer these ??'s first.

How far ON AVERAGE will you Attempt a shot on game at a maximum with perefect shooting conditions? 100 yards? or up to ??00 yards. FWIW I'd guess mebbe as many as 90% of all WTails are killed in Texas at around 75/100-150 yards.

How well do any of your guns shoot it's smallest 5 shot groups at 100 yards? 150 yards? 200 yards?? thats the gun I would learn to shoot at distance on regardless of caliber.

Point of Reference ...the term MOA means Minute of Angle and 1 MOA equals all shots are under an inch, as measured Bullet Hole Center to Bullet Hole Center at 100 yards, or inside 2 inchs at 200 yrds yadda yadda.

Answer these questions and then you can begin to answer your initial questions.

MPBR aka Max Point Blank Range can be visualized as a "tube" of bullet paths at a given range. The longest MPBR bullet impacts will come from a rifle that has a faster Muzzle Velocities than a slower rifle, shooting bullets that are the most efficient in flite aka highest Ballistic Coefficient number for it's caliber and weight, and still capable of killing the game animal being hunted. Sectional Density is a numerical designation of a mathmatical estiamtion of the bullet's ability to provide the deepest penetration on the target's composition medium...ie a Game Animal's flesh, mud, trees, stacks of newspaper yadda yadda

So MPBR is a collection of unique to that combination of data information using the Highest BC game bullet, at the fastest most accurate MV, using a single sighting point with no guesssing the holdover or using broad average guestimates provided by BDC crosshairs ...and keeping the rise and fall of the bullet path within a "tube" of target space. Think being able to aim a rifle at the same Point Blank hold at a 250 or 400 yard target and knowing that even though your are zeroed dead on at 150 or 250 yards your bullet path will land on the game animal target within a predetermined Kill Zone.

Have fun learning these aspects of accurate successful shooting at game animals.

IMO Consistent accuracy at longer distances beginning at about 250/300 yards will take IMO a totally different kind of scope that uses the Mil Dot system estimation and dialing a resetable top turret to move the cross hairs to dead on & a side A/O turret or scope front A/O tube to properly focus (aka Adjustable Objective) the crosshairs for the clearest image at further than the average factory preset of usually 100 or 150 yards ...and does totally away with holdover and is in fact the most accurate sighting system, and found in scopes with First Focal Planes where the croshair does NOT change sizes depending on distance focused at, instead of the 2nd Focal Plane scopes that are the most common and less expensive.

I'm no "expert," but... For those calibers, I prefer a 200 yd zero, if I plan on using Kentucky windage. For relatively short range calibers (.300 BLK, 30-30), I prefer a 100 yd. zero, no matter what.

If I have my scope marked for the round I'm using, and I can dial it in, or if I'm running a ballistic calculator, I generally leave it on a 100 yd zero and adjust as needed.

Really, no matter what anyone else says, It all comes down to what you are most comfortable with. Either will work just fine.

I use Hornady ammo not only because of reliability but it sure helps that the box shows you the ballistics if zeroed at 200 yards. Since I'm looking at likely max distance at 300 yards I use the 200 yard zero and have a reference to reinforce how high to aim at 300. It shows a drop of 5.7" at 300 yards so with brisket at average large deer at 18 " I can aim at the top of the deer and hit in the money most likely. You can adjust for high shoulder or heart/lungs, etc.
