Tips/tricks for keeping DOPE on the gun

[Korgs130]

After taking a DMR class with Jim Kauber a couple of years ago, I make a small copy of my DOPE card and tape it to my stock. Ammo, outside air temp and elevation of the DOPE included. This is on my LMT MWS w/ NF SHV 4-14 F1. I have the a similar DOPE setup for my BCM 14.5 ELW-F w/ 1-10 Razor.

So really stupid question - that’s to dial on a turret right? Not some reference to the stadia?

It works either way. You can dial the turrets or do holds, as long as the reticle and turrets match each other (i.e. they both use MRAD) then it works. Some people prefer to do holds for both elevation and wind as much as possible, others like me will dial elevation and hold for wind.

As for the "best" way to keep dope data with your gun, there are lots of methods. When I did my first PRS rimfire match, I went and created a series of cards and stuffed them into a arm board so I could glance down at my arm. It turns out that it was unnecessary since the target distances are known ahead of time. So I instead just slapped a piece of tape the top with the dope for each target in the stage. Other competitors had little attachments mounted to their guns that held little plastic boards for doing the same. The super fancy ones had digital e-paper style readers that displayed the dope for the stage.

Here's a picture of the arm board I use. It's a Tyr Tactical minimalist model.


The actual cards are like 2" x 4.25" and I work them up using JBM ballistics and my own chrono data. Then I laminate them. This particular one is for my Tikka T1x 22lr



I saved a template that anyone can download and make their own versions here. If you don't mind a little self promotion, it's at the bottom of this article: Custom Dope Cards. These don't have to go in an arm board. You could easily tape it to anything.

Like Brigand said, it works either way. The mils are referencing the stadia graduations. The NF on my MWS has more of a conventional reticle with exposed turrets, so my preference is to dial for distance (elevation) and hold for wind / target movement. With the 1-10 Razor having the Christmas tree reticle and capped turrets, my preference is to hold for both distance and wind.

This is great but what do you do if you laze something at 342 yards?

2.1 mils…


Though I’m dubious on this data as we are seeing 0.9 between each 100y then 1.4 mils between 400-500 but as we lose speed up to 1.1mils from 500-600. Something ain’t right

Caveats- Work guns, same guns with similar dope, dialing for elevation and holding wind. I memorize 100-500 in 50yd increments, backed up with 100yd increments written on the front lens cap. I've also sharpied or paint-penned dope along the L side of the receiver (R handed shooter). A card/table on the receiver extension can work, but those tend to come off or need more movement to view.

Small changes in atmospherics may not matter much/enough to warrant changes. Run the tables, shoot to true, and see for your gun/load.

For me running 69gr Black Hills SMK ammo at 2700 FPS (I feel this is fair for a 16-18" DMR?)

I get

200y 0.5
300y 1.3
400y 2.4
500y 3.7
600y 5.3

So 0.5, 0.8, 1.1, 1.3, and 1.6 between each distance, respectively.

I'm not seeing how he could be getting 0.8 at 200y but only 5.1 at 600y.

Korgs can you share your projectile, sight height, and speed?

I do the same thing on all my rifles, albeit taped to the side of the stock- instantly tells the shooter where the rifle is zeroed / for what load / altitude / temp.

Yeah, it's not a replacement for Strelok Pro nor a gucci chart with laser range finding and environmental quirks.

But it gives you a quick reference and a starting point to TLAR it / interpolate as needed.

In short, it's better than nothing which is what you'll have with only your rifle without it.

I don’t mean this in a condescending way whatsoever but what is the issue with memorizing? It’s 5 sets of numbers.
