Please help me. I'm being retarded and I can't figure something out that's killing me.

Take scope A and scope B, both with first focal plane reticles:
A) Has a reticle spanning 10MRAD in all directions, and zoom to 10x
B) Has a reticle spanning 20MRAD in all directions, and zoom to 20x
Now zoom both to 10x- an object 5MRAD tall in one scope should be 5MRAD tall in the other, right? In fact zoom doesn't even matter for FFP reticles here, right? And Scope B should appear larger to the eye, right?
So how in the fuck does Scope B's reticle appear smaller to the eye?? Distances aren't the same MRAD for the two scopes- what???
This is what I'm seeing. My scope (reticle pic related) at 10x shows totally different MRAD readings compared to some YouTube video of a different reticle on the same zoom, despite both reticles having sub-tensions in MRAD.
Video here:
https://youtu.be/3KRMP_FLm48?t=69

What the fuck am I missing?
Please make me feel retarded.

I don't have the answer to this but I am curious as well so I will give you a friendly bump
>>
>>42924918
>So how in the fuck does Scope B's reticle appear smaller to the eye??

Maybe something to do with eye relief and exit pupil diameter (eyepiece). Objects should be the same size (in mrad) through either scope. For FFP, zoom shouldn't matter (like you said). The size of the object in mrad depends only on its size (duh) and range. But the angle your eyeball sees depends on the magnification as well as moving your head back and forth with respect to the eye position for which that zoom value is specified.

I'm not sure about all rifle scopes. But in my experience (with astronomical telescopes as well), eyepieces behave differently if you move your eye in and out. Some maintain the same image angle and cut off the field of view. Others present a 'constant' image size, so if you move your head closer, you perceive a larger image. Right up to the point where you press your eye right up to the scope. And then 'Blam!' Smack yourself in the forehead.

Scopes in video:
>SFP in MOA for Sightron
>FFP in MOA for Vortex

Your Vortex:
>FFP in MRAD

Why are you claiming the scopes in video are MRAD?

>Now zoom both to 10x- an object 5MRAD tall in one scope should be 5MRAD tall in the other, right?
Correct.

> In fact zoom doesn't even matter for FFP reticles here, right?
Also correct.

>And Scope B should appear larger to the eye, right?
No. If they're both set at the same magnification, and if the other optical properties of the scope like FOV, exit pupil, etc, are the same then they should appear the same looking through the scope.

The only thing that should match in your hypothetical example are the height of the objects relative to the MRAD marks on the reticle. If the same object is X MRAD tall in one scope then it should also be X MRAD tall on the other.

But like the other anon said, it seems like you're comparing apples and oranges here.
>>
>>42927403
This is probably relevant actually, as the video has the camera so far back from the scope that you can see plenty of context/background around the scope...

>>42927524
Ah fuck! Praise be! I AM retarded! I was referring to the FFP in the video, but my dumb ass was thinking MOA and MRAD were close enough to be negligible- they're totally not and that explains why the size of 10MRAD looks the same as ~30MOA, THANKS.

>>42927567
Yeah actually that was a typo- I meant "Scope B's RETICLE should appear larger to the eye [because it spans more MRAD]".
But yep, I had a stroke and forgot how far 1MRAD is from 1MOA.

No, I'm serious. In fact Tigrs for US export in the 90's had to be made in separate batches from rifles for domestic buyers. I'm not sure if laws have changed since then, but in the 90's they get the accuracy you can expect out of a VEPR in 54r.

It's time to get creative with your ideas for weapons we could potentially build but for some reason don't.

I'll start:
>electromagnetic mass driver at least three miles long
>projectile is an aerodynamic tungsten torpedo at least six feet and eighteen long
>with the assistance of a ferromagnetic sabot, the mass drive catapults the torpedo at high speeds
>attached to the rear of the torpedo is a nuclear charge much like project orion to give the torpedo an additional boost
>efficiency of nuclear charge could potentially be maximized with use of antimatter catalyst instead of traditional explosives
>cities could be flattened with little if any fallout
>space colonies could be blown wide open
>torpedo too fast to shoot down like archaic ICBMs
>only real countermeasure is laser ablation which would require extremely precise timing

Honestly other than the railgun section, I'm sure that producing thermite ammunition and a firearm for it wouldn't be too difficult. It would just be so dangerous to handle or fire that you'd be risking a lot. For example, if you hit a wall with that round it's probably going to burn through which could cause some shit if you shot near anything else dangerous. Not to mention, at least with normal bullets, on the off chance that you have a ND then you probably just put a hole in the wall but with that your wall is now on fire. Also imagine the sheet shit storm if one thermite round ignited while in magazine or ammo dump. Just one big superheated boom

A nuclear bullet.

Literally a super-miniaturized fission device that can fit into the barrel of a medium to high caliber handheld gun. Ultimate yield would be tiny compared to conventional nukes (only about 5 tons of TNT, or .005 kt), but it would still be devastating to whatever is the target.

Its often commonly said that one of the benefits provided by the dominant naval power at the time, previously the RN and today the US Navy, is that it ensures the safety of global maritime trade and energy supplies etc. But how exactly is it doing this and from whom is it securing this? Most national navies would be able to deal with piracy in their own waters, and in any case the US Navy has been no more effective against pirates in Somalia and Indonesia than other countries patrolling the area.

The case could be made that the US Navy is ensuring freedom of international navigation against state actors that do not respect international laws and have the capability to disrupt maritime traffic like Iran and China, but those two faggoty countries would be equally fucked from any disruptions since they are dependent on maritime trade to export oil (Iran) and manufactures (China) for their economic survival. So they may want to flex on others but ultimately its their own interest to guarantee freedom of navigation.

Ultimately, the only countries that would be fucked by the US Navy disappearing are those that depend on US naval protection directly for survival (e.g. Taiwan), failed states with no ability to repel simple pirates and the continental USA itself, although just the size, population and isolation of the last makes it difficult to invade even without a massive navy protecting its coasts. The size of the US internal economy means that the USA does not require international maritime trade to survive either.

So who is the US Navy protecting international shipping from?

OP makes the argument that coastal countries already do secure their own oceans. To use your analogy, the oceans are a giant warehouse, and the US has installed central heating. However, every country in the warehouse already has their own jackets and ovens, so central heating isn't actually required.

Who here actually has a plan for the boogaloo? You don't have to post it because OPSEc, but who actually has a plan for what they'd do should 1776 2.0 occur? I do

Going hunting with a muzzleloader for the first time this year. I was thinking if doing it le old Kentucky rifle style. Should I go with flintlock or percussion cap? Anybody have experience with both? Tips and tricks? I own an 1858 remmi revolver, but that's the extent of my experience.
>>
>>42925787
Percussion if it's your first time. Flintlocks have a retarded steep learning curve and will shit all over you if you're unprepared; percussion is fiddly enough to appeal to your inner rainman while still being relatively forgiving. Also use the lightest rifle you can shoulder. Some guns, like the Lyman great plains hunter, are good little shooters but goddamn if they don't get heavy and unwieldy real fast out in the woods. Don't be afraid to use a cheap inline rifle for hunting until you get your feet wet. They may not be as sexy as some hand carved Pennsylvania barn gun, but they're forgiving as fuck for new shooters and if you decide that black powder hunting isn't for you then you're not out as much money.
