Mounting Options for Ballistics Data Displays & Come-Up Tables

When shooting any match that requires moving back and forth between multiple target distances it is very handy to have your ballistics data, i.e. your “come-ups”, placed within easy view. That way you can instantly see your elevation for various target distances in seconds. This can really help a PRS/NRL competitor on timed stages. And having a convenient “Dope” display of elevation at various distances can also benefit varminters who are shooting critters. In our varmint hunters we targeted p-dogs from about 80 yards out to 500+.

PRC DOPE Roller QD Ballistic Data Turret

The PRC DOPE Roller QD Ballistic Data Turret provides a handy, low profile display of windage and elevation data. You can see your “dope” without breaking position from behind the rifle. Then simply rotate the knob to display data from various distances. The ballistic data is placed by wrapping a simple 1″ x 3″ adhesive address label around the outside surface of the DOPE Roller. This handy quick-detach roller retails for $64.95 from Precision Rifle Components.

MDT M-LOK Data Card Holder

The MDT M-LOK Data Card Holder has an adjustable neck allowing you to easily position your ballistics data for optimal viewing. Data entries are written on on a reusable card that attaches with Velcro. The Data Card Holder Kit comes with hardware to mount to any M-Lok rail. In addition the card holder fits directly to an MDT ACC chassis attachment point. This MDT kit includes: M-LOK Data Card Holder, Wet Erase Data Card, Wet Erase Marker, and installation hardware. NOTE: The Card Holder sticks out about 6.7″ when fully extended, but arm links can be removed to make the arm shorter. The unit folds flat for storage. This complete kit is $59.95 at Creedmoor Sports.

Warne Universal Data Card Holder

The Warne Universal Data Card Holder easily attaches to the scope tube, in left or right configurations, for a universal fit. Data is displayed in a convenient location to make quick and accurate target transitions, and the articulating arm allows for low profile storage while not in use. The Warne Universal Data Card Holder retails for $88.49 at Warnescopemounts.com. Three ring sizes are offered: 30mm, 34mm, 35mm. A 50-pack of Warne Data Card label refills is currently $16.99 from Warne.

Scope-Cover Mounted Ballistics Table
Another option is to place your ballistics card on the back of the front flip-up scope cover. This set-up is used by Forum member Greg C. (aka “Rem40X”).

With your ‘come-up’ table on the flip-up cover you can check your windage and elevation drops easily without having to move out of shooting position.

Greg tells us: “Placing my trajectory table on the front scope cover has worked well for me for a couple of years and thought I’d share. It’s in plain view and not under my armpit. And the table is far enough away that my aging eyes can read it easily. To apply, just use clear tape on the front objective cover.”

Cheap But Effective — Tape on the Stock with Ballistics Data

At the 2021 Nightforce ELR Steel Challenge, Applied Ballistics guru Bryan Litz wrote his come-ups on blue masking tape applied to his stock. He did this based on a tip from Chase Stroud. With the tape applied behind the action, the numbers are easily visible. This “cheap trick” does work apparently — Bryan won the match with a convincing victory over 220 other shooters.

Cheap But NOT So Effective — Numbers on Hand

Many of us have scribbled some come-ups on the back of a hand or on our forearm using a marking pen. That can work if you only have a couple distances to deal with — say 100 and 300 yards. But if you want a more complete Come-up table, get one of the card-holders shown above. Writing numbers on the skin is generally not such a good idea….
