Q&A Leupold Mark 4HD 2.5-10x42mm FFP TMR

[Stocky]

I think in forms words, these are inconsistent. Which is a real bummer

Glad to hear they are aware of the rokslide drop test. I’m surprised she said their military test are far worst, when the scopes have been inconsistently passing/not passing

I’d really like for it to pass as it seems like a great hunting scope

Potentialy the test is not for ability to hold zero and passing is a lesser standard ie you could rezero it.

Looks like Stick flogged on one of these over on the campfire and had some similar results. Not great.

Took the Mark 4HD off the rail, cleaned the barrel and finished with lock-ease.
First shot was a wee bit hot, which I have not seen before. I've finished with the graphite for about a year now and haven't seen any 1st shot issues. Shot the six then shot 2 at 600 to confirm all is where it should be. This is the 24x pr3 version, 3x fired brass.

Got to see a Mk 4 HD in person while in Alaska last week while the Rep was visiting Granite View Sports. Great shop by the way. Quite a nice scope, turret feel, reticle was nice. Was a 6-24 model with christmas tree. I asked the rep if she was familiar with the Rokslide Drop Tests. She said "We are and our military tests are far worse than that" or something to that effect. She seemed quite knowledgeable and I was pleased to see the drop tests are at least on their radar. After a lot of discussion, I got the impression this scope might be able to pass. Fingers crossed because if it will pass I will buy one and drop my own. If it fails miserably, I won't bother.

Their test uses ability to rezero as a pass. Not ability to still hit the darn thing you need to.

Like saying a car passes a crash test because you can replace parts or can bend it back.

I agree. I think a lot of people confuse the drop test which looks for a scope losing zero with the scope breaking and those are two entirely different things.

 

[Dobermann]

You don’t. Unless you get a T3 Arctic.

Or a Steyr Scout.

I know it doesn't do all that you said you wanted later in the thread, but just putting it out there that another option does exist.

And interesting that Jeff Cooper not only also insisted on backup iron sights for a field rifle, but also a negative comb.

Just sayin'!

Also, shooting at distance- glass quality is a bit hazy. Not sure what the issue is, but it is noticeably “soft” compared to the Maven RS1.2 and SWFA 3-15x (at 10x).

What distance where you when you noticed this? Where does it start to become noticeable with your eyes?

740 yards. It got pulled off a rifle for a restock, and is now back on it. I will update.

 

[Formidilosus]

Updated.

 

[TX_Diver]

If you leave it does it continue to drift up? Or does it drift up .2 then stop?

I'm not buying one of these but just curious. It seems like a lot of people (myself included) may not see a .2 Mil shift over just a few shots in the field?

Sorry I have to ask, is the Larue c-note a legitimate option (for ARs or possibly bolt guns)? Or is it a meme range toy. I truly can’t tell.

Updated with some zero checks.

So riding around in the truck is making it shift high, then vibrates back down? It’s not holding zero?

 

[Formidilosus]

Correct. There is a .2 to .3 mil vertical shift randomly happening.

 

[Marshfly]

That's pretty standard for a lot of scopes unfortunately.

Guys miss or wound animals. Then go to the range to check it. Shoot once, it's off. They chalk it up to them "pulling it." That shot vibrates the erector back into position. The second shot is on target so they call it good.

Rinse and repeat. Missing and wounding crap along the way. Never realizing they have junk on their rifles.

This scope model is and has been so close to stable that I think it merits some larger groups on zero checks to increase significance of results.

Haha. I “wish” too.

But, I will next time.

Form, related to the prior post, how are you determining that these two and three shot groups aren't in the rifle's cone? (Forgive my ignorance; genuinely here to learn ...!)

Form, related to the prior post, how are you determining that these two and three shot groups aren't in the rifle's cone? (Forgive my ignorance; genuinely here to learn ...!)

The rifle’s 10 round groups (and one 20 round) are all under 1.5 MOA, and the 1.5 was only one I think. The vast majority have been 1.1 to 1.3 MOA. After zeroing (20 round group) it has twice needed a down .2 mil correction (.4 mils total)- so lost zero high, which is exactly what the scopes did in the drop evals; all three of them when they lost zero, they went high.

As for only using three rounds or even one round to check zero, if the rifle has been zeroed correctly (it was) than any shot, and especially multiple shots that land outside the cone means something has moved.

Let’s say the gun is what the worst group was, so 1.5” at 100 rounds.

The white “X” ring is 1.695”





This shot is well outside the cone (1.25” high)-




Even if you go to the middle of both, it is outside the cone (.82” high)-
