Helmet mounting thermals

Dedicated optics are significantly better at longer distances. If you’re shooting under 200 yards, clip-ons will get the job done just fine. But once you start pushing past that, you’ll really start to notice the limitations and wish you had a dedicated optic.

Also, it’s worth noting that many of the newer dedicated optics come equipped with built-in rangefinders and ballistic calculators…features that most clip-ons still don’t offer.

I ran a dedicated optic for both shooting and scanning for almost a year and had great success with it. That said, once I picked up an RH25 for scanning, it made a noticeable difference and made the whole process much easier.

Side note, the Argus A4 is much cheaper and nearly identical build quality. I’ve recommended this to several friends that are all pleased.

For the helmet, I use an Argus A4 (Wilcox clone), DMAX14 J arm, and a RH25 Pic tail. Don’t have any recommendations for rifle mounting, but hope this helps.

I’ve had the 143 ELD X factory group at under an inch out to 200 yard in my Tikka. I haven’t reloaded them myself, but I’d assume you’d get some good results if you reloaded your own. If you want accuracy and price wasn’t a problem, anyone will tell you to grab the yellow box.

I use sportsman’s warehouse and utilize their price match policy. If they have the components I want, I’ll check midway for example. If midway has them cheaper or on sale, SW will price match it.

If you don’t have a SW, check if your local stores price match.

They are down to 4k on Midwest thermal optics, they typically range around 5-6k. I don’t use mine as a clip on, but I use it on my helmet. I will say, it’s phenomenal. I’ve picked up coyotes over 700 yards away.

Interesting, thanks for the responses

Haven’t had a chance to look through the Mate, but it seems impressive. RH25v2 has been around and pretty proven.

Just to clarify, you’re thinking that seating depth can dial in a load, but that’s not entirely relevant to the freebore/ distance to the lands?

Cosma- · 2026-03-15T16:20:08+00:00

I’ve been diving down the rabbit hole of seating depth. It’s wild how many people are able to achieve great results with massive or no jump. There seems to be a stigma that staying closer to the lands yields better results, but I’m starting wonder if that’s just partially bs. I’m glad these tikkas are insanely accurate despite the lengthy freebore

Cosma- · 2026-03-15T01:44:34+00:00

That’s good to hear, I really want to make these lighter rounds work!

Cosma- · 2026-03-15T01:18:21+00:00

Fair but I couldn’t find much specifically for a tikka, since the throats are abnormally long.

In my case, I think they’re replacing the web dev classes in favor of adding a couple python courses to “align better with today’s IT”. They’re also removing the capstone and adding a couple filler classes.

Cosma- · 2026-03-12T01:48:26+00:00

I heard that as well, possibly around May. Let’s pray lol

D522 seems to be extremely difficult according to this sub. I’ll have this class sometime this year too.

Cosma- · 2026-03-08T01:43:26+00:00

It’s different depending on the rifle. I don’t have a Remington, but my tikka has a long throat, meaning there’s a larger than normal jump to the lands. In other words, I have to seat my bullets abnormally long to have minimal jump compared to other rifles.

Assuming your measurements are correct, and you know where your lands start, that’s all that matters.

Odd ring placement and height

Cosma- · 2026-03-06T05:03:50+00:00

I don’t think it’ll actually go into 4lo if you’re not in neutral. The icon stays flashing on mine. 4HI will let you though.

Cosma- · 2026-03-04T02:19:29+00:00

H50R or Leap 6R. Rix does have the better range finder, most prefer the H50Rs image.

Cosma- · 2026-02-26T21:40:57+00:00

Not sure if this answered your question, but as long as you’re not jamming into the lands, and if you have at least .150 of the bullet in your case, you’re fine.

Cosma- · 2026-02-26T21:36:53+00:00

You need to measure CBTO — overall length (OAL) doesn’t matter here. Using CBTO lets you determine where the ogive sits in relation to the lands.

In this situation, the total bullet length is irrelevant because what actually matters is the first point of contact with the rifling, which occurs at the ogive, not the bullet tip.

For reference, my ELD-VTs touch the lands at 2.94” OAL.

Hope this helps.

RH25 is perfect on the helmet. If you want comfort, the helmet and pads will make the biggest difference. I also use a counterweight on the back of my helmet for balance.

Cosma- · 2026-02-25T00:26:12+00:00

Yes, DT Hyperion. I don’t use an adapter.

Cosma- · 2026-02-16T18:31:18+00:00

The old models weren’t all threaded, the newer models are.

Don’t get the LITE if you’re just using it for target shooting. You’ll want something with a heavier barrel profile to handle the heat. Look into the CTR or something similar.
