Gun Sales Boom Spurred by First-Time Buyers

We all know that gun and ammo sales have risen dramatically in recent months. Firearms sales through large retailers are up 39% compared to last year, according to SportsOneSource, a company that provides research for the outdoor industry.

What may be surprising is that there is a “new audience” of Americans who are buying firearms for the first time. Gun vendors are reporting a major increase in firearm purchases by novice shooters and first-time gun-owners. According to a recent article on the Time Magazine website, Americans who have never owned a gun before are now motivated to arm themselves: “A new market of gun buyers is emerging. [Oklahoma Gunshop owner] Miles Hall estimates that some 80% of his sales since the election have been to first- and second-time gun purchasers, many nervous that this may be their last chance.” According to the Time article, many Americans are purchasing firearms due to fears that crime may rise as the economy falters: “Americans are afraid of this economy. As a result, they’re getting locked and loaded.”

In sporting goods stores nationwide, and on internet gun forums, people are wondering “where has all the ammo gone?” Well, based on the sales of firearms, the answer may be that ammo supplies are being snapped up by the same folks who are buying guns for the first time.

Eastern Jr. High Power Clinic & Championship, June 20-26

Young people are the future of the shooting sports. The Civilian Marksmanship Program (CMP) promotes junior shooting with a variety of programs for young shooters, including CMP High Power and service rifle clinics. This June, in cooperation with the North Carolina National Guard, NC Rifle & Pistol Assn., and the USMC Rifle Team, the CMP hosts a major event for junior competitors.

The Eastern U.S. Junior High Power Clinic and Championship will take place on 20-26 June at Camp Butner, North Carolina. This event offers a full week of clinics, coaching and competition for junior service rifle competitors. Enrollment is now open for the Clinic and Championship. CLICK HERE to register.

CMP Junior High power clinicThe clinic offers instruction on and off the firing line covering both shooting in individual matches and shooting as a member of a coached team. During the 6 days of clinics and competition, juniors fire a 600 yard 20-shot prone slow-fire match, an 80-shot Bushmaster Trophy Match (4×20 shots), a Billy Atkins Team Match (two-person teams with each firer shooting a 50-shot NMC with coaching), a CMP 50-shot EIC Match and an Infantry Team Match.

The fee for the 2009 Clinic and Championship is $100 which includes on-base housing at Camp Butner, lunches (Sunday-Thursday) and evening meals (Sunday-Thursday).

Tips For Using Sensitive Electronic Scales

Some of our forum members have observed issues with the Acculab VIC-123, an 0.001g precision electronic balance made by Sartorius. (The Denver Instrument MXX-123 is very similar.) The two main complaints seem to be sensitivity to drafts, and instability of zero, causing weight read-outs to “drift” over time. We have seen the latter problem in less expensive scales such as the PACT. (Read PACT report).

Acculab VIC-123 digital scaleForum member Ronemus, who lists his profession as “instrumentation scientist”, offers the following advice:

“It is necessary to isolate the scale from drafts and vibrations. Laboratory scales with this sort of resolution (.001g) generally have a housing around the pan with sliding doors for access and vibration isolators in the feet. Those scales cost thousands of dollars, and some features must be cut to reach a price we’re willing to pay. Unfortunately, the instruction manuals accompanying our scales generally aren’t very good at spelling out the steps necessary to have them operate to our satisfaction.

A small draft (one you can barely feel) can easily shift the reading a few tenths of a grain, so some sort of enclosure is needed. I use a cardboard file box with one end cut out, so 3 sides and the top remain, and that’s good enough for 0.1 gr (6 mg) stability; however, that may not be sufficient for 0.01 gr.

For stable zeros it’s necessary to warm up for at least a few hours (they’re generally left on continuously to avoid drift) and keep the room temperature fairly constant (within a few degrees).

Inexpensive scales are also susceptible to electrical noise, either riding the power line or through the air. Power line noise can be eliminated with a good filtered power strip (I recommend a Tripp-Lite Iso-Bar), not just a surge suppressor. Cordless and cell phones, fluorescent lights, wireless computer networks, baby monitors, etc. can cause problems at short range, so they should be kept away from the scale as much as possible.”

We have also observed that these scales MUST be properly leveled. They just won’t work right if they are tilted even a litte bit. This editor recently worked with an Acculab VIC-123. Its owner was complaining that it would drift and the read-out was constantly flickering. Well the scale was mounted on a plastic folding table with a top that was warped and bowed in the middle. It was virtually impossible to level the scale properly. The scale was also directly under a large ventilation fan. Once we transfered the scale to a bench with a solid flat surface, leveled the scale front to rear AND side to side, and ensured the scale was isolated from air currents, the scale worked perfectly.
