Scope Recommendation - 400 yards

[peterk123]

Any chance this is going on a very accurate state of the art blackpowder gun?

 

[OXN939]

I look forward to your opinions!

You would pay a lot fewer taxes by going with a 3-9x40...

Maybe something like this?

I was thinking the same thing. Thread looks really similar to that one

Damn, looks like March is out of the game. Otherwise that 8-80x56 would be perfect for a 400 yard and in rifle.

Yeeaaahhh….. the critiques are just going to happen here. Especially with the ridiculousness you are wanting.

@Soj51hopeful - The critiques are unwelcomed. I'm asking for opinions on a few scopes. Not about how I'm using them.

I would look at the Athlon Cronus BTR Gen2 UHD 4.5-29x56 with the APLR5 reticle if going MOA or APRS6 if MIL.

I checked it out but I didn't care for the reticle. I do like the 4.5-29x aspect though.

I would check out the trijicon tenmile 5-50x56. 35x on the top end isn’t enough to get you out to 400 yards.

That's SFP.

you know what you need from actual experience with high end optics. You won’t need the advice of an Internet forum to guide you.

I have owned a lot of high-end scopes, but I'd still like opinions.

This has to be a troll bot.

No.

No, it's a .308.

I don't pay taxes on firearms or scopes, so this will be a purchase I don't worry about that on.

Not sure why this matters, but this is going on a Browning X-Bolt that currently has a 5-25x56mm Schmidt & Bender on it. I didn't care for it.

Someone said something about Black Powder? Not sure where that comes from, but last year I got a brand new Arrowhead Obsidian. It's an amazing muzzleloader and should be for 10 grand (500yd MOA performance).

Low light performance is going to be really poor even with alpha glass with 25x and 56mm objective because it creates a 2.2mm exit pupil projected onto a 4-5mm dilated pupil. Even with great glass and 50mm+ objectives you typically need to back off to 8x-12x to maximize image quality.

More magnification is not always a good thing, honestly is generally a bad thing with the zoom ranges mentioned regardless of glass quality.

Look at a horse through your current scope so we can see the image quality

I'd like to think that my 5-25x50mm Schmidt & Bender would qualify as "Alpha Glass", but it isn't that great when looking out at those distances (the parallax is also set to maximize clarity at that distance). I'm wondering if upgrading from a 30mm tube to ~34ish might help and upping it to 56mm.

I don't have a horse and there aren't any around. Seems like a random data point?

34mm tubes will not transfer more light than 30mm, you just get more erector travel.

I think you really should be looking at lower magnification ranges. I’ve killed out to 500 yards with a 2.5-10x42 NXS at last light. Quite honestly any scope that cost more than $1,000 has adequate glass quality to not be worth splitting hairs over.

I don’t think you fully realize the optical tradeoffs involved with higher magnification.

LMAO - tube diameter doesn’t effect light transmission, so going from 30 to 34mm won’t help.

Rather than laugh at me, could you kindly explain why having a wider conduit for light to flow through wouldn't translate to improved light transmission?

I figure if the objective lens is larger, that gathers more light, then if you channel it through a larger funnel (tube diameter), you'd get more light at the eyepiece. That seems to make sense.

I won't consider lower magnification ranges but appreciate your input.

 

[Kurts86]

The size of the image projected onto your eye is the Objective diameter divided by the magnification, this is called exit pupil. If the exit pupil size is smaller than your pupil the perceived image quality will degrade. Low light pupil size varies by individual but for adults is typically 4-5mm. This is independent from % light transmission. Raising the magnification will decrease the exit pupil size.

Going into a higher magnification also narrows your field of view, it makes it hard to stay on target to spot your own shots and harder to recover for follow up shots. You are looking at PRS scopes meant to be used midday when you pupil might be 1-2mm because of the ambient brightness rather than hunting scopes.

There are a dozen guys here telling you the same thing. Less magnification is often a good thing and most PRS shooters are running high magnification scopes from 12-18x most of the time. I run a 20x FFP scope for hunting and it often lives at 6-12x for shots as far or further than you are talking about.

I think you would probably benefit from some basic optics research and some professional shooting instruction. I don’t think your gear is the problem here, I don’t think you know how to use it or understand what you need.

When i shoot over 300 yards, I often find myself on 10-16 power. Im not a fan of 6x @ 400, but to each their own.

This is independent from % light transmission. Raising the magnification will decrease the exit pupil size.

So if the size of the image projected is based on the Obj diameter divided by the magnification, wouldn't increasing the size of the objective diameter (for a fixed magnification) improve the quality?

Maybe I can keep 4-16x (probably will go up to maybe 20) but go from 50mm to 56mm or greater.

Thoughts?

See comments above. Just looking for feedback on the ones I noted, not critiques of "why".

How is feedback complete without honesty?

Honesty is appreciated regarding the scopes listed.

Seems every thread is getting taken in a different direction lately. Guy is asking about 3 scopes, he has narrowed it down to. He specifically asks if anyone has any experience with said scopes. Then he gets met with all kinds of guys telling him, that is not what he wants or needs..... Now if he asked "is this a good scope for my intended purpose, or would you recommend others?" then I would expect the answers in this thread.
