When they're on a Leupold MK4 6.5x20x50. The last 2 times I've gone to the range, I've checked zero at 100yards. Then I give it 4 clicks elevation. The rounds land 1.3" high. I know these scopes aren't perfect but that's a LOT error in my book.

Pretty sure it's 1/4" As dumb as I am, that MOA stuff makes me think too hard.

Re: When do 4 1/4" clicks NOT equal one inch"
Like Wil stated... 1/4 inch vs. .25 MOA...
Here's a great way to check your scope... Not mine...Compliments of Lindy...
Check your Turrets for 1/4" vs. .25 MOA...

Re: When do 4 1/4" clicks NOT equal one inch"
Even if it were in MOA, 4 clicks would not move it 1.3",... it would only move 1.047" if it were in moa.
I had two 4.5X14 Mk4's, over the years and had two good days with both. They do have a good warranty, program, I've used it many times.

Re: When do 4 1/4" clicks NOT equal one inch"
Like has been stated before 1/4 inch does not equal .25 MOA. MOA is equal to 1.047 inches. Most scopes including leupold are built on IPHY but call in MOA.
Also due to the design of the mk4 line of scopes there is slack in the turrets. To function properly the shooter need to dial past the point of correction he/she is trying to achieve then dial the turret back to the correct POI. This coupled with the MOA/Mil setup of leupold scopes is why I no longer own any.

Re: When do 4 1/4" clicks NOT equal one inch"
First, WHAT is "IPHY?"
Second, when you write that I have to dial past the point of correction - HOW much past? How many clicks?
I've heard that the parallax adjustment is like that.

Re: When do 4 1/4" clicks NOT equal one inch"
(1) When they are 1/4 MOA clicks and not 1/4" clicks. Four of them would give you 1.2" at 100 yards.
(2) When you are not 100 yards from the target.
(3) When you have high measurement errors.

Re: When do 4 1/4" clicks NOT equal one inch"
IPHY= Inches per hundred yards
There is no set amount of correction you have to dial past your correct POI. However when I had a mk4 I'd always dial 1-1.5 moa past where I wanted to be then back down. I never had this issue with the parallax, and it shouldn't be an issue. This issue with the elevation and windage turrets comes from the dual erector spring setup used in the mk4's.

First, how many rounds did you fire at the 100yd zero, then how many at 4 clicks up? There is a lot more room for error when checking adjustment the less adjustment you make.
Next time, try a group of 5-10 shots at a dot on the bottom of an 8.5X11 sheet of paper then dial 40 clicks (I'm only referencing by "clicks" since you did), then shoot 5-10 shots. Measure the distance between the centers of those two groups and see what you have........

Re: When do 4 1/4" clicks NOT equal one inch"
If your rifle is not consistant with a particular ammo then you will get results all over. Just because you changed you point of aim 1/4 moa up from the previous round fired, doesn't mean you next round will be exactly 1/4 moa up. You first need to shoot holes right on top of eachother before using them to test the mechanics of your optic. Try marking your target with meausured dots and test your point of aim that way.

Re: When do 4 1/4" clicks NOT equal one inch"
The best way to test the scope click value is not shooting groups, just set the rifle on sandbags, aim at a precise starting point on a large measuring tape or target with 1" grid, and start cranking...
This way you remove shooter/rifle/ammunition errors, and just test the scope.

Re: When do 4 1/4" clicks NOT equal one inch"
Man there are so many good suggestions here and variables in the "equation" I didn't think of. At this point, I'm going to have to go out and start experiementing. I have to say though, that I've never knowingly purchased a scope that had MOA increments so I don't think that's a factor.
To answer a couple of questions, I fired 3 shot groups. The saying "Three shots tests the gun, five shots test the shooter" is very true with me. The fewer I shoot, the more accurate I am.
As far as what I'm shooting - reloads. Win brass, 175 SMKs BR-2 primers, Varget. I'm getting about 2650fps out of them.
OneEye that was pretty smart of you to suggest the range might not be 100yards. I've lazed it in the past and it was like 99yards. As far as measurement errors - I was shooting at a target with 1" squares. For me, the bullseye was atypically large but was being used in this instance simply because it was handy. Typically, I shoot at a single dot that's about .30 wide. In this instance, I had a 3 shot vertical string with the bottom hole at 1.3" As near as I can measure (I'm using digital calipers), the nearly vertical string measured .33 from center bottom to center top hole. That's pretty typical for me and that gun.
I appreciate everyone's responses and look forward to continued comments.

Re: When do 4 1/4" clicks NOT equal one inch"
For this to truely be a test, the target has to be EXACTLY 100 yards away, the target has to be EXACTLY plumb and EXACTLY perpendicular to the bore. The ammo has to be EXACTLY the same shot to shot and the shooter has to as well.
There are a lot of variables to account for, that said...0.253 inches is a lot to account for. Are you positive you did not dail in 1.25 MOA (5 clicks)? That would yield a perfect result of 1.30875 inches at 100 yards.
You should do a box test with a much wider spread, like 30 MOA, and see what the results are.

Re: When do 4 1/4" clicks NOT equal one inch"
When I run a tracking test, I do it on a 36-40" target backer at 100 yards.
Start with your aiming point at the bottom of the backer.
If you kick a shot out, don't sweat it. By the time you have dialed to the top of the target backer you will be able to clearly see if there is an error.

Oops, this was meant as an addition to long shot's post. As I am sure his point was that MOA is an angular unit of measure and is only thusly equivalent to 1.047 @ 100. Sorry LS38.

Re: When do 4 1/4" clicks NOT equal one inch"
I always check the tracking of my scopes out to 40 MOA or 10 mils depending on the scope graduations. I have a board for both. Here's the MOA board
Funny story though, I had a 6.5-20 Leupold and after about 15 MOA the scope didn't track right and was off. I just made a constant to multiply my data with to get it where I needed it.

Re: When do 4 1/4" clicks NOT equal one inch"
Your scope is junk brother. I'll give you $100 for it and I'll even pay shipping.
Seriously, you cant test that way. The shooter, the ammo, the distance, the scope, nothing is perfect. Like was said earlier, if you could stack bullets @ 100 all day every day then have at it but......it aint hapnin.
okie

Re: When do 4 1/4" clicks NOT equal one inch"
+1 on all of the above. Sandbagged weapon and or the tracking board as shown above. Just my .02 but assuming 1/2 MOA accurate rifle = up to .5in error in any direction (more than accounts for .3 variation in impact point) Also if the rifle is .308... arguably the bullet hit the same spot
