The R-F Cam Cradle is a smart new product that lets you securely mount a Laser Rangefinder (LRF), digital camera, and spotting scope all on a single tripod. The “game-changing” feature of the R-F Cam Cradle is that it allows you to colimmate (i.e. precisely align) all your optics on the same spot. This way you can simultaneously aim all three devices at a long range target by simply moving the tripod head. A tactical shooter can easily range his target while watching the wind though his spotting scope. And the long-range hunter can range and film his prey as he watches it through the spotter. This unit costs $179.95 from DefensiveEdge.net.
You’ll find a detailed product evaluation of the R-F Cam Cradle on the LongRangeOnly.com website. Reviewer Sam Millard uses the R-F Cam Cradle in the field with a variety of optics and rangefinders. Millard explains how the R-F Cam Cradle conveniently allows combined use of spotting scope, LRF, and compact video camera.
Millard was very impressed with the system: “I field-tested the R-F Cam Cradle in the mountains of northern Idaho and the wide open spaces of eastern Wyoming. I believe the most effective way to use the cradle is in a long range ambush; get the spotting scope, camera, and LRF aligned on a landmark, then lock it down. The LRF and spotter won’t be aligned perfectly, but they’ll be well within the field of view of each other, requiring only a gentle tilt of the tripod to center the beam of the LRF on the target. At ELR distances, a well-supported LRF is crucial to obtaining an accurate range. This mount makes it easy, and doesn’t require displacing your spotting scope to get it done.”

Having a video camera mounted in alignment with spotting scope is great for Long Range applications notes Millard: “The camera mount is my favorite feature of the R-F Cam Cradle. It allows co-witnessing the video camera to the spotting scope, then aiming the field of view of both with one movement of the tripod head. This is a great improvement to the normal way of recording the shot and spotting at the same time, which previously required two tripods or a clamp-on head for the camera, both of which required separate aiming of the camera and spotting scope.”

The prestigious GAP Grind tactical match took place 16-18 October, at the K&M Shooting Complex in Finger, Tennessee. Here’s a “sizzle reel” video showing highlights from this year’s match, which drew talented competitors from across the nation. Held in association with the Precision Rifle Series (PRS), this year’s Grind features a Pro/Am format with professional and amateur competitors aiming for individual and team honors.
Watch GAP Grind 2015 Video (Loud Soundtrack):
Lots of Action, with 20+ Stages
The GAP Grind is a challenging, “high tempo” match with minimal down-time between stages. This year, over the course of 20+ stages, competitors each fired 200+ shots at a variety of steel, paper, moving, and reactive targets out to 1,200 yards. Targets varied in size and difficulty based on distance and time allotted. Most stages included “stressors” — i.e. time limits or required movement(s).
Hornady has introduced an innovative new single-stage press with some very impressive features. The new-for-2016 Hornady Iron Press™ features a super-strong, pyramid-style cast-iron frame with an open front. A very clever optional “automatic” priming system shuttles primers from a vertical tube in the back to the shell-holder in the front. We’ve never really seen anything quite like this before. You really should watch the video — it shows the patented auto-priming system in action. This system appears to be a very smart piece of engineering — good job Hornady.
Watch this Video to See Gravity-Fed Shuttle Priming System (00:45, 01:00):
The broad top of the beefy (26-lb.) Iron Press can hold case prep tools (such as chamfer tool and case-neck brush) and/or a box for bullets or brass. NOTE: This is NOT a turret press — you can only use one die at a time. However, Hornady offers an accessory “Die Caddy” (sold separately) that can hold up to three (3) more dies. That way you can quickly switch from a sizing die to a seater die (or vice-versa). What Hornady calls the “Accessory Mounting Deck” gives quick access to items such as trays for bullets or cases, chamfer and deburr tools, case neck brushes, primer pocket cleaners and other accessories. The Iron Press comes with the Lock-N-Load® bushing system which allows for rapid die changes.
Optional Automatic Priming System
The optional auto-priming system is a real selling point for this new press we think. When you move the press handle rearwards, a horizontal bar toggles back to pick up a primer from the column in the rear of the press. Then this same bar move forwards to place the fresh primer in the center of the shell-holder. Hornady explains: “The available gravity-fed Automatic Priming System (sold separately or with the Lock-N-Load® Iron Press™ Reloading Kit), combined with the Accessory Mounting Deck, increases reloading efficiency by allowing more processes to occur simultaneously. The Iron Press™ is the first of its kind to allow the ability to deprime, pause, and remove the case to chamfer & deburr … then replace and prime.” Do watch the video to see the priming system in action.
Nightforce Optics has just launched a new monthly newsletter. This free, subscription-based digital publication will offer information on optics, target shooting, hunting, and other topics of interest. The debut October issue, released this week, features match reports, tactical shooting hold-over advice, plus a TECH TIP explaining Parallax.
PARALLAX – What is it and Why is it important?
What is Parallax?
Parallax is the apparent movement of the scope’s reticle (cross-hairs) in relation to the target as the shooter moves his eye across the exit pupil of the riflescope. This is caused by the target and the reticle being located in different focal planes.
Why is it Important?
The greater the distance to the target and magnification of the optic, the greater the parallax error becomes. Especially at longer distances, significant sighting error can result if parallax is not removed.
How to Remove Parallax
This Nightforce Tech Tip video quickly shows how to remove parallax on your riflescope.
While keeping the rifle still and looking through the riflescope, a slight nod of the head up and down will quickly determine if parallax is present. To remove parallax, start with the adjustment mechanism on infinity and rotate until the reticle remains stationary in relation to the target regardless of head movement. If parallax has been eliminated, the reticle will remain stationary in relation to the target regardless of eye placement behind the optic.

Our friend Dennis Santiago was doing pits duty during the Small Arms Firing School (SAFS) phase of the CMP Western Games. Here are some views from the pits at the Ben Avery Range in Phoenix, Arizona. Dennis also took a video from the pits during live fire. Listen to rounds zip over-head and impact into the berm beyond the targets, in the video below.
Watch Video with rounds flying over the pit zone:
Dennis reports: “Here’s a slice of life at the receiving end of live fire. This is a rapid fire stage as seen from the target pits at the 2015 CMP Western Games. The targets are placed up in the air. The bullets go through them over the heads of competitors protected behind an earth berm. The bullets land in a designated impact area (berm) beyond the target frames.”
At the CMP Western Games, participants shoot, score and do pit service. The pit workers are positioned on a catwalk behind a concrete wall. There is a thick, earth-works berm on the other side.
These four photos show the substantial changes in the shock wave and turbulence patterns for the same 7.5mm bullet at different velocities. The “M” stands for Mach and the numerical value represents the velocity of the bullet relative to the speed of sound at the time of the shot. Photos by Beat Kneubuehl.
“Going transonic” is generally not a good thing for bullets. The bullet can lose stability as it enters the transonic zone. It can also become less slippery, losing BC as a consequence of dynamic instability. In this video, Bryan Litz of Applied Ballistics analyzes what happens to bullet stability (and BC) as projectiles approach the speed of sound. Transonic effects come into play starting about Mach 1.2, as the bullet drops below 1340 fps.
Transonic Ballistics Effects Explainedby Bryan Litz
What happens when the bullet slows to transonic speed, i.e. when the bullet slows to about 1340 feet per second? It is getting close to the speed of sound, close to the sound barrier. That is a bad place to fly for anything. In particular, for bullets that are spin-stabilized, what the sound barrier does to a bullet (as it flies near Mach 1) is that it has a de-stabilizing effect. The center of pressure moves forward, and the over-turning moment on the bullet gets greater. You must then ask: “Is your bullet going to have enough gyroscopic stability to overcome the increasing dynamic instability that’s experienced at transonic speed?”
Some bullets do this better than others. Typically bullets that are shorter and have shallow boat-tail angles will track better through the transonic range. On the contrary, bullets that are longer… can experience a greater range of pitching and yawing in the transonic range that will depress their ballistic coefficients at that speed to greater or lesser extents depending on the exact conditions of the day. That makes it very hard to predict your trajectory for bullets like that through that speed range.
When you look at transonic effects on stability, you’re looking at reasons to maybe have a super-fast twist rate to stabilize your bullets, because you’re actually getting better performance — you’re getting less drag and more BC from your bullets if they are spinning with a more rigid axis through the transonic flight range because they’ll be experiencing less pitching and yawing in their flight.
To determine how bullets perform in the “transonic zone”, Bryan did a lot of testing with multiple barrels and various twist rates, comparing how bullets act at supersonic AND transonic velocities. Bryan looked at the effect of twist rates on the bullets’ Ballistic Coefficient (BC). His tests revealed how BC degrades in the transonic zone due to pitching and yawing. Bryan also studied how precision (group size) and muzzle velocity were affected by twist rates. You may be surprised by the results (which showed that precision did not suffer much with faster barrel twist rates). The results of this extensive research are found in Bryan’s book Modern Advancements in Long Range Shooting.
Bryan notes: “A lot of gunpowder was burned to get these results and it’s all published in layman’s terms that are easy to understand”. If you’re interested in learning more about transonic bullet stability, you may want to pick up a copy of Bryan’s book.
On its YouTube Channel, the USAMU offers “Pro Tips” videos providing expert instruction on rifle marksmanship. One helpful video covers up/down angle shooting. In the video, SFC Emil Praslick III, one of America’s best long-range shooting coaches, explains how to determine up/down angle, and how to compensate for the angle using scope clicks. Praslick explains how gravity always works as a constant relative to the flat-ground distance to the target (which is distinct from the actual straight-line distance to target.)
The flat-ground distance is the actual distance over which the bullet will be affected by gravity. Use this as the basis for your elevation corrections. As Praslick explains, “this [flat-ground] distance will get less and less as the angle to the target increases [either up or down].” Once you know the straight-line distance to the target AND the exact angle of your shot, simple math lets you calculate the flat-ground distance to the target. Basically, to determine your flat-ground distance to target, you multiply the cosine of the shot angle by the measured straight-line distance to the target.
Application to Long-Range Hunting Since the effects of angles increase with distance, Praslick explains that: “Unless the angle is extremely severe, [a hunter] really won’t notice these effects at ranges of 200 yards or less.” However, for long shots, hunters definitely need to compensate when taking angled shots. Praslick recommends that hunters print out a small chart with the cosines of common angles (20°, 25°, 30° etc.). In addition, hunters need an accurate ballistic table for their rifle and particular ammo. This should show the elevation corrections (in MOA or clicks), for 200 yards to the maximum range at which you may take a shot.
SFC Emil Praslick III is an instructor/coach with the USAMU. He also has served as a coach and “wind guru” with numerous U.S. Teams in international competition, including the U.S. Palma Team, which recently participated in the World Long-Range Fullbore Rifle Championship in Australia. Praslick has also coached the U.S. F-Open Class Team.
Hunting season is right around the corner. That means its time to inspect all your hunting gear, including your scope set-up. A proper scope installation involves more than just tensioning a set of rings — you need to consider the proper eye relief and head position.
In this NSSF video, Ryan Cleckner shows how to set up a scope on a hunting or tactical rifle. Ryan, a former U.S. Army Sniper Instructor, notes that many hunters spend a small fortune on equipment, but fail to set up their rifle to use the optics optimally. Cleckner likens this to someone who owns an expensive sports car, but never adjusts the seat or the mirrors.
Ryan notes that you want your head and neck to be able to rest naturally on the stock, without straining. You head should rest comfortably on the stock. If you have to consciously lift your head off the stock to see through the scope, then your set-up isn’t correct. Likewise, You shouldn’t have to push your head forward or pull it back to see a clear image through the scope. If you need to strain forward or pull back to get correct eye relief, then the scope’s fore/aft position in the rings needs to be altered. Watch the full video for more tips.
Tips on Mounting Your Scope and Adjusting Your Comb Height:
1. Normally, you want your scope mounted as low as possible, while allowing sufficient clearance for the front objective. (NOTE: Benchrest shooters may prefer a high mount for a variety of reasons.)
2. Once the scope height is set, you need to get your head to the correct level. This may require adding an accessory cheekpad, or raising the comb height if your rifle has an adjustable cheekpiece.
3. Start with the rifle in the position you use most often (standing, kneeling, or prone). If you shoot mostly prone, you need to get down on the ground. Close your eyes, and let you head rest naturally on the stock. Then open your eyes, and see if you are too low or too high. You may need to use a cheekpad to get your head higher on the stock.
4. If your scope has a flat on the bottom of the turret housing, this will help you level your scope. Just find a flat piece of metal that slides easily between the bottom of the scope and the rail. Slide that metal piece under the scope and then tilt it up so the flat on the bottom of the scope aligns parallel with the flats on the rail. Watch the video at 8:40 to see how this is done.

A few years ago, some folks released a video that showed how gun control laws might operate in a fictional California of the future. The video shows how State Agency pre-authorization would have to be obtained before a handgun could be employed for self-defense in the home. Sound far-fetched? Well, it turns out that this satirical video was not that far from the truth. That disturbing vision of the future is coming to pass… at least in some parts of California.
The City of Los Angeles recently passed an municipal ordinance that would require handguns to be locked up (or otherwise disabled) when kept in the home. Modeled after a similar law in San Francisco, the Los Angeles ordinance makes it a misdemeanor to keep an unsecured handgun in a home. There are some exceptions to the locking rule (such as when the owner has the firearm in “close proxmity”), but this Los Angeles ordinance still imposes onerous burdens on citizens who might need a firearm to defend themselves in their own homes.
Under the new Los Angeles city ordinance, there is no “pre-authorization” requirement — at least not yet. But that could be the next step, as this video shows…
Think about it… how can you respond to an intruder if you have to call and ask for permission to access your own firearm. How that scenario might unfold is depicted in this video, a chilling preview of gun ownership in California. The video is a dramatization, but it shows what could happen in the Golden State in the not-too-distant future.
We’ve seen a huge surge of interest in extreme long-range shooting in the past year. Guys are testing their shooting skills at one mile (1760 yards) and beyond. However, it’s kind of pointless to toss expensive bullets downrange if you can’t see your hits (and plot the misses). For that reason, a good target cam system is an essential piece of kit for any extreme-range shootist. Here is a report on a system developed by Forum member Mark Dalzell (aka “MDSlammer”) a couple years ago. With elevated directional antennas, this system worked reliably at 2300 yards (1.3 miles).
Mark Dalzell likes to shoot at extreme long range in the Nevada Desert. (See 2300-yard Hits in VIDEO). In order to see both hits and misses at ranges out to 2300 yards, Mark assembled a target-cam system that broadcasts multiple video cam feeds wirelessly to a receiver on the firing line. Down-range, Mark positioned a high-gain antenna. This was key — without the antenna the system’s useful range was less than 1000 yards. But with the hi-gain antenna Mark gets very clear signals from 2300 yards.
