Custom Target Cam System with Rest-Mounted Monitor

Diana Target Cam Wifi system wireless camera video benchrest

Dave Diana is a clever fellow. He not only fabricated his own wireless Target Cam system, but he invented a mount that places the receiver/monitor unit conveniently next to his bench rifle. The hooded view-screen actually mounts to his SEB front Rest via a bracket. The monitor unit includes wireless receiver and a short directional antenna (see below):

Dave says his new CCTV monitor bracket on the SEB NEO rest is “working as planned”. However, after taking these photos, Dave did make a modification. Dave explained: “I found moving the monitor over to the left-hand side was more shooter-friendly. I can stay in a natural shooting position, look at the screen, see my windflags and shoot with little movement. The next task is to add a coffee cup holder somewhere to house my group tightener double expresso!”

Target Cam Monitor Has Built-In Receiver
Dave built a very nice system. He tells us: “The security camera is a 27x power zoom camera housed in a weather proof case that also houses the wireless transmitter. The monitor has a built-in receiver, and I am running spiral polarized antennas on both ends. The system will run all day long on the waterproof-cased, game-camera batteries.”

Here are the internals of the wireless camera system. Note the antenna at right.

Barrel Care and Maintenance — Expert Advice

Shooting Sports Lohman Barrel

Ask 10 shooters about barrel cleaning and you’ll get 10 different opinions. This reflects that fact that different fouling problems demand different solutions. For example, solvents that work well for copper may not be the best for hard carbon (and vice-versa). To come up with the right solution, first you must understand the nature of the fouling in your barrel.

Chip Lohman, former Editor of Shooting Sports USA Magazine, has authored an excellent article on barrel maintenance and cleaning. Chip’s article, Let the BARREL Tell You — Match Barrel Care, can be found in the Shooting Sports USA digital archives. In this article, Chip shares the knowledge of a dozen experts including barrel-makers Frank Green (Bartlein Barrels), John Krieger (Krieger Barrels), and Tim North (Broughton Barrels).

The debate about the proper care of a match barrel is a hot one, spiked with folklore and old wives’ tales, Lohman said. He and his staff set out to set the record straight: “We tried to interject some science into the discussion of cleaning a match barrel,” he explained. In his article, Lohman writes:

Why worry about a little barrel fouling when the throat is subjected to a brutal 5,600° F volcano at 55,000 PSI? To investigate these and other questions about taking care of a match barrel, we spoke with a dozen experts and share their knowledge in this first of a series of articles.

After listening to folks who shoot, build barrels or manufacture cleaning solvents for a living, we concluded that even the experts each have their own unique recommendations on how to care for a match barrel. But they all agree on one thing — the gun will tell you what it likes best. Because the life expectancy of a match barrel is about 1,500 to 2,500 rounds, the objectives of cleaning one should include: preserve accuracy, slow the erosion, and remove fouling — all without damaging the gun. This article doesn’t claim that one cleaning method is better than the next. Rather, we set out to interject a little science into the discussion and to share some lessons learned from experts in the field.
