Finally a Good Shot Marker Stand

[Jettheterror]

Hey guys just wanted to share this "shot marker" stand from Detour dynamics it looks like a great piece of kit. I'm sure you long range ninjas could appreciate it.

Nice execution. This product desperately needs a better set up

 

[ZiaHunter]

Fabricated this stand in my shop using TIG welded 2"x2" square aluminum tubing. Uses 1" EMT for legs and can be set at different heights. Lightweight and breaks down easily for transport.

Looks like the targets the F-class guys setup at the club..

I have to look at this from the perspective of anything downrange is going to get shot eventually so you want it to be cheap and easily fixed or built like a tank so it can shrug off hits. You can't really protect the microphone clusters so the first solution is probably the right one.

How about this:

You can assemble, break down or fix the frame with a screw driver in a few minutes and this stuff is fairly torsionally ridged. Not sure how the microphones mount but if it is something odd, I can model a 3d printable bracket for you guys if someone wants.

It's nice theirs comes as a full kit so you don't have to figure out a lot of guess work.

We used Shot Marker targets at Gunsite XLR to calibrate rifles with FFS and was so impressed I ordered one as soon as soon as I returned home. Far superior to the previous method of spending a full day of sending rounds down range at KD targets. We were able to calibrate two rifle in one morning and spent the rest of the class banging UKD targets out to 2200. The target frame I built will allow 3 MOA at a 1000.

I've used things like the oakwood controls H bar but not these. What is the recommended and maximum spacing for the corners?

After looking at the way the mag base mounts, this style 2020 bracket would be better:

https://www.amazon.com/dp/B07GDVV2SR/ref=sspa_dk_detail_6?psc=1&pd_rd_i=B07GDVV2SR&pd_rd_w=sWW4z&pf_rd_p=085568d9-3b13-4ac1-8ae4-24a26c00cb0c&pd_rd_wg=gVjRD&pf_rd_r=RHHMET9ATST3HYDE60RD&pd_rd_r=dc71909e-a972-4a21-8bef-9fdfb5f5e9b4&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExSjM2VVY5V1YyODQ2JmVuY3J5cHRlZElkPUEwNTg1NzUwMzkxWlA3MDhVRTFaQiZlbmNyeXB0ZWRBZElkPUEwODI1MDg1U0tQUVNQVTEzNkhFJndpZGdldE5hbWU9c3BfZGV0YWlsJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==

That with a few M5 screws and the T-nuts in that kit you can mount that magnetic bases at the corners. Cant tell you how long the screws would need to be for the bases but this should cover the range:

The TIG'd bracket is sexy, I'll grant you. Think I'd be pissed to get it shot though.

[ZiaHunter]

Well if you can't shoot sub 3 moa at a 1000 you probably being shooting at it in the first place.

 

[ZiaHunter]

-Alex

Not sure if there is a recommended maximum spacing but critical to have a square frame and the sensors equidistant.

 

[Sandow the Heretic]

Duh... and yet that logic doesn't stop half as many people as it should and we both know it. Saw a shooter print a 5" group at 1500 yards on the frame. Ask Walt, he was being rather colorful the entire time lol... At a match a month ago I had a shooter manage to get three hits on target legs in 4 shots taken. left leg, right leg, target, right leg and managed to sever it... Our fault for not having heavy enough protection but that was some magically bad shooting. At Ringneck Ranch I had a shooter that on two sequential targets 100s of yards apart manage to whistle rounds passed the cameras repeatedly and they were 4 fucking mils to the left of the plates! Anything downrange will get shot.

Not sure if there is a recommended maximum spacing but critical to have a square frame and the sensors equidistant.

The extrusion would make that brainless. They come cut with pretty tight tolerances but the way the brackets work, you can square them up even if they are radically different lengths.

True. This frame is for my use only to calibrate rifles and practice F Class. Not sure what size frame Cory was using at a 1000+ but no doubt pretty large. Good practice to verify windage and elevation on steel before sending rounds through Shot Marker.

 

[CoryT]

The 1k frame is 6’x8‘, and we confirm on a plate prior to shooting the target. I’m adding a 1500 yard target and it will be 8x10

 

[Jettheterror]

Those are some really cool frames you guys built in your shops. I just liked the Detour Dynamics way more because it can break down and can fit in the wife's car if I need to andI don't have to figure anything out. One and done!

 

[b6graham]

needs some AR500 at the corners to protect the sensors

It is always recommended to use a trueing target safley adjacent from the target stand to make sure the shooter, rifle, and wind gods are on the same page.

that's great at 1k. 1500, 2000, 2500 not so much

"We're going to need a bigger boat." Hahaha yup definitely gets wild at those distances.

 

[Lowlight]

I am too lazy to build one, that Detour stand looks like the ticket for a heavy use range

 

[CoryT]

Well, that depends on the frame size and known precision of the system. The only expensive item is the sensor hub, I place it on edge and bolt a 4" plate in front of it. The sensors are pretty tiny, as they are point on and $40 gets you a universal spare. The 1500 yard frame I'm making now is 10' x 8 ', plenty for even a new rifle being calibrated. One test shot on a nearby plate establishes gross windage and elevation. The 1K frame is 8'x8', I've never had a client get close to the frame. I've personally shot with that frame at 2000, it's plenty big for a known rifle unless the wind is howling and gusty.

I just bolt up 3"x1" aluminum tube, use wing nuts and it breaks down to straight sections for transport.

 

[Lowlight]

Cory has a nice one, super simple

 

[CoryT]

I just added a third frame to the stable. We will now have a 1500/2000 yard target. In fact, we can now set three targets in line at 200/400/600 and capture 4 velocities on a single shot, as well as relative shot locations. The new frame is just under 10'x10'. We are also adding downrange wireless wind sensors for the calibration ranges.

Nice. I wish we had the land on the east coast to build a facility like this. Probably the only thing I miss about living and growing up out west. Open land.

Sorry for my stupidity… what’s the string for?

 

[CoryT]

The crossed string make sure you post the aiming point in the center of the sensor block. I just use some strips of fiberglass tape, hold the aiming point perfectly even in a high wind without vibrating the frame.

 

[CSGambill]

Put this together over the last few days. Can stand on its own or hang on a 2x4.

That looks really friggin sweet! Though I can't imagine the pain to get those T-posts in perfectly aligned

 

[Gustav Jimny]

Well, not in the class of you guys, but I got a Shot Marker at a price I could not refuse, and since a Suzuki Jimny is somewhat limited in internal space, I needed a fold-up target that could fit on the, small, roof rack.
Borrowed heavily from F- Class John, this is what I came up with.

 

[jmorris]

I wanted a large frame and wanted it a bit more portable. I cut and machined the cross bars square on the ends and installed 1/4-20 thread inserts and drilled the verticals as a matched set. I use a 7/16 nut driver to assemble with the 4 bolts once I get there.

In the playing around mode now though and need to do some more testing. Thinking about ditching the plastic holders and just sticking the sensors directly to the steel frame, I made some weld on tabs that I drilled and tapped for 8-32 screws for the mounting brackets but then thought a 1/4” section of 2.5” box tube welded to the frame would do the same job as the 3d Printed holders with better ability to be kept out in the elements.

Bringing this thread back from the dead…
I’ve been fortunate to be able to shoot on Quantico’s 1000 yard Range 4 nearly every weekend for the last 20 years or so.

A couple of guys I shoot with have been Shot Markers for the last year so I figured I’d forgo my usual 25x15 IPSIC steel target and get one of the systems.

After ordering a Shot Marker last February I had a bunch of aluminum delivered to my metal fabricator/hot rod guru buddy and gave him a primitive drawing so he could assemble a frame for me that would fit one of the target carriages on the range.

He began to assemble the fame when he got to a stopping point on the 69
Shelby convertible he was working on…

During assembly he said the frame was the flattest, squarest thing he’d ever made. He couldn’t wait to start welding on it and warp it….

When he finished it, I had to figure out a way to transport it, so I built a rack for the bed of my beat up F150.

I took the frame and mounts to the range to test proof of concept. It worked!

The Shot Marker arrived week before last and I began assembling the sensor mounts, etc.

Believe it or not, you can get five sheets of 60x60 inch cardboard for $52 shipped. A free wooden pallet is included.

This past Wednesday i calibrated the target @ 100 yards at the Northern Virginia Gun Club that’s 110 miles down and back I95 from my home.

The reason I mention the distance is because although the calibration was a complete success, the adhesive on the packing tape I used to attach the backer to the frame failed about 10 minutes after I left the range….the hot sun melted it and the backer ended up folded over my tailgate @ 65mph….

I hit Home Depot and got a 4x8 foot sheet of corplast and some white duct tape.

I was all set to RSO and shoot my target on Range 4 tomorrow when the Marines needed the range at the last minute and canceled us.

Maybe next weekend…

 

[TACC]

Thats a very cool setup, keep us posted on your success

 

[Sandow the Heretic]

Spent a lot of time in those pits...

Looks like a good build. FZ-G1 is a great choice for the interface. Nice and bright even in full sun.

Only concern is a rather obscure rule from a few years back about metallic targets downrange needing to be Hardened steel. Pretty sure that rule came out of S3 rather than QSC. It was the result of injuries from ricochets off mild steel targets though and shouldn't logically apply to an aluminum frame but you might want to clear it ahead of time unless you think begging forgiveness is a better way to go. If so, just paint it coyote tan so it looks like wood at a glance.

Interesting. RC (and WTBn) have been hinting since last year that one of the Lloyd ranges (2, 3 or 4) were going to be converted to electronic targets.

 

[Sandow the Heretic]

I'd give it another decade. Once it is 20 years past when it was time to change, I'd expect them to act on it lol...

[VSP968]

Interesting. RC (and WTBn) have been hinting since last year that one of the Lloyd ranges (2, 3 or 4) were going to be converted to electronic targets.

For three months, there was a complete Shot Marker system mounted in a wooden target frame, sans the access point (receiver), with all the sensors, cables and the sensor hub, leaning against the wall under the overhang at position 25 of Range 4, like they were weather testing it. Then it was gone.

Saw a white board in the RC conference room with “Calvin Lloyd Complex Improvements ” listed as number three…

When I asked what the improvements were, I was told “ We’re only responsible for the ranges and the RSO’s , not capitol improvements. I read that as “Don’t ask.”

 

[VSP968]

After two months of improvements on the Calvin Lloyd complex, we were finally able to open Range 4 and I got a chance to try out my new Shot Market target system.

I’ve gotta say all the waiting was worth it. I’ll never shoot steel again on Range 4 again. Apologies to @Fixr whose spot on the range I swiped while he’s on vacation.
