setting my scope at 100 yards

[XTR]

now that yo have determined that your distance is from the turret, have you weighed your bullets and sorted them by ogive, turned necks and sorted your brass by volume, weighed powder to .002 grains, checked bullet runout to .001 and sorted your primers? Are you patching after every shot?

(That should keep him busy for a while

Hi there when you are setting you scope at 100 yards Is it from the end of the barrel our
at the action of the barrel thank you

You are not that good to know the difference!!!! Unless you can distinguish .01 on target!!!

Im glad yall could decipher that post. My decoder ring is smoking.

Hold on....while I take a shot of FAMOUS GROUSE!!

If you dead on at 100 yards you will need for your bullet to impact the 100 yard target around 28'' above the point of aim. Larry

With his 30-30?

A true 100 yard zero is set from the center of the elevation turret, being that it's where all your adjustments are made.

Yes I have a 300ft tape I roll out for zeroing.

don't forget to account for the stretch in the 300 ft. tape!

Dead on the ground . ;D I was talking a average long range gun . ;D

You guys have way too much time on your hands. As a builder of a large range I can tell you that distances to target holders are typically measured from the firing line, and on most benched ranges that coincidences with the front edge of the benches. Differences in ballistic calculations that would result from a different definition would for practical purposes become entirely lost in the noise. While I enjoy the internet, and the discussions that take place there, sometimes I get the impression that fellows forget the difference in being on line and shooting. There are lots of real problems out there that typical shooters would benefit from solving. IMO this is not one of them.

Amen.

I've never once bothered to verify the distances at the shooting range and it's never once affected my zero's or my accuracy/precision. Even when hunting and I need a clean kill. Just shoot the thing and put some holes in the paper.

The only time this would have any bearing would be if you were trying to determine a correction factor for the actual adjustments of the scope.

If this is what you are doing each scope may be calibrated a little differently and this would be a question that should only be answered by the manufacturer. Typically it will be to the objective or turrets.

Now lets assume you recieved bad info and measured 100 yds to your barrel instead of the scope, but you did it very accurately and within 1". Lets also say you used a scale or target with marks within .01" of an inch across 6 or 7 feet and is perfectly perpindicular to the optic. Now you check the calibration of the optic and are able to not move the scope at all and discern all readings of the reticle location within .01"across the entire range of the scope.

Unfortunately all this hard work was done at the muzzle instead of the optic and resulted in a correction factor of .992 instead of 1.000 and now at 1000yds (30 moa) you are off by .2 moa. Whew better start over!

Shoot the rifle, record the drops, fudge the b.c. to match. You will have accomplished the same thing and you can spend the saved time shooting.

I'm splitting wood now, so this is a great "breather" thread. I just can't go all day, anymore.😆

As a friend of mine liked to say:
Measure it with a mike,
Mark it with chalk,
Cut it with an axe.

I can see a primer thread coming on....

Boxcar and the bushman hit it on the head, measure from the turret in order to calibrate your scope adjustments. Some of the advanced ballistic solvers take a calibrated scope into account when giving a solution. If a first shot hit is what you are looking for at long range, every little bit helps.

If anyone is interested my company makes a replacement turret cap that has a really nice matte black hook built into it that is specific to the actual adjustment center of the scope. This makes it very easy to hook your tape and get an exact measurement to the target. Since all scope designs vary please include the make and model of the scope. These caps are available for all Leupold, Nightforce and March scopes.

As Hillary Ramrod Clinton once screeched "At this time, what difference does it make?" Typically, the 100 yard targets are measured from the front edge of the bench. James
