Davis Power-Boosting Scope Lens Insert

Gene Davis has a new product that boosts the magnification of Leupold, Sightron, and Weaver BR scopes. A threaded ring with a Zeiss lens simply screws on to your scope behind the eyepiece, using the threads provided for lens caps. (Consider it an eyepiece extension). Both 2X and 3X models are available. The 2X version increases image size about 15% while the 3X boosts the viewed image roughly 30%. Hence, on a 36X scope, Davis’ 3X booster creates the equivalent of a 46X power scope. Starting with a 45X Leupold you can get 58X power. Many long-range BR shooters are using this product and reporting to Gene that they can see bullet holes at 600 yards and beyond for the first time. However, there is a price for the extra magnification–the reticle will appear slightly larger, and the image will appear somewhat darker. But, according to Gene: “the image darkening is almost imperceptible during prime daylight hours.” We think Gene’s invention is a winner–a great way to get more magnification at a low cost–$100.00. We also like the fact that, unlike an internal boosting job, you can simply remove the Booster if you want to return to the original magnification level.

Davis Scope Booster Magnifier screw-in

Gene reports: “If the scope has screw-in lens caps, these Optical Boosters perform well. We started with a product for the Leupold Competition scopes. We now have Optical Boosters for Weaver T36 and Sightron 36BR as well. We are working on other brands of scopes and the earlier Leupold scopes that do not have threads for the cap. The Optical Boosters do a fantastic job for old or poor eyes. They fit any Leupold scope that has screw-in lens caps, as well as the Weaver and Sightron 36-power target scopes. The Boosters require no internal modification and will not effect the factory warranty. The Optical Boosters (either 2X or 3X) cost $100 delivered.” To purchase, contact Gene Davis at (740) 503-4486 or gdavis10 [at] columbus.rr.com.

Here are reports from two users:

Dick Wright: “Mine is on a 45X Leup…. It’s now a 60X Leup. I got it at the Super Shoot. Excellent optics. You have to re-focus the crosshair. I used it at the Oscoda match where we had lots of mirage. It was a 200 yd. score match and I could see my .22 bullet holes easily. This is totally subjective but, if anything, it made it easier to see. It’s an optical booster that really works for a mere [$100] bucks. All you have to do to reverse the process is un-screw it.”

Joe Pellegrene: “I just got back from the range using my new 3x magnifier on a 45x Leupold. Now it’s a 60x scope and I can’t imagine how I ever lived without it. If anyone’s having trouble seeing their bullet holes on the target this product is well worth the money. It’s easily the most significant piece of equipment that I bought yet.

I plan on using it on several different rifles since you just unscrew it and screw it on the next one. It that takes about 10 seconds to do that. The fine cross hairs on my Leupold were magnified, but so was the target so everything seemed proportional. It’s so much nicer seeing what you’re trying to hit. Now if only Gene would make one for the Nightforce scopes. You can put me down for one Nightforce magnifier. Gene, I wouldn’t mind shooting a 56x Nightforce!”

Reloading Tips: Neck-Turning and Powder Measures

Bullet-smith Victor Johnson, Johnson Precision Bullets, sent us these useful tips:

Neck-Turning: I found that a 1/2 inch Dewalt drill with a keyless chuck will hold many caliber cases without an adapter. Just place the case in the chuck and twist it hand tight. Does the same work as a $250 case lathe. When neck-turning cases, you can hold the drill in one hand and the neck-turning tool in the other. But it’s much more efficient if you clamp the 1/2″ drill in a vise (with some carpet for padding). Then it’s very easy to control the turning speed and add/remove cartridge brass.

Powder Measures: If you’re throwing powder charges in the fall or winter and have problems with bridging or sticking powder, use a ground wire. This will help reduce static charge that causes clinging and clumping. I have a 25-foot piece of real small wire with alligator clips on each end. It’s that long so I can run it down the hall to a water pipe. Use the wire tie from a bread bag to hold it in a small roll to put in the range box. When using it at the range use a 6″ nail from the co-op or Lowe’s / Home Depot and just push it into the ground.

On July 4th, Remember the Minutemen

On this nation’s Independence Day, we should remember the “shot heard ’round the world”. It is quite possible that there would be no United States of America (in the form we now know it), but for the courage of a small band of ordinary citizens, armed with hunting rifles. The militias of Concord and Lexington, Massachusetts were the first colonists to provide organized, armed opposition to British rule in the Americas. It is their fighting spirit that we celebrate today.

battle of Concord

The Battles of Lexington and Concord
Having learned about arms stockpiled in Concord, on April 19, 1775, British General Gage ordered an estimated 700-800 regulars to march to Concord to seize arms, gunpowder, and cannons. (Gage also wanted to arrest John Hancock and Sam Adams, reported to be in Lexington.) Learning of the planned British action, Paul Revere rode to Lexington to alert the militia. Hancock and Adams went into hiding and the Lexington militia (120 or so men) formed up under Captain John Parker. When the British reached Lexington, they arrayed in battle formation on the Lexington Green. Parker told his men: “Stand your ground! Don’t fire unless fired upon! But if they want to have a war, let it begin here!” The British then advanced. A shot was heard, and the British regulars charged and attacked Parker’s force. When the smoke had cleared, the British suffered only one man wounded. However, eight Minutemen died, including Captain Parker’s cousin, Jonus, killed by bayonet.

The British then continued to the Concord arsenal. After securing the roads leading into Concord, the British troops proceeded to destroy powder and weapons. In the process the Concord courthouse was accidentally set on fire. The Minutemen, formed up on the hills outside Concord, saw smoke and thought the British were burning the town. The Concord Minutemen then attacked the British at Concord’s North Bridge. By most reports the Militia fire was much more accurate than the British volleys. Two Redcoat officers were killed, along with many enlisted men. Surprised by this, the British broke ranks and retreated. The Minutemen chased after them and captured the North Bridge. The British then abandoned Concord and marched back to Boston. The Minutemen hounded the Redcoats in retreat, peppering the Brits with sniper fire all the way back into Boston. John Parker lead his Lexington Militia in one ambush of the retreating British, known as “Parker’s Revenge”. Concord/Lexington Battle Map.

Who Were the Minutemen?
As early as 1645 in the Massachusetts Bay Colony, some men were selected from the general ranks of town-based “training bands” for rapid deployment. Men so selected were designated as Minutemen. The Minutemen were often 25 years old or younger, and they were chosen for their enthusiasm, political reliability, and strength. They were the first armed militia to arrive or await a battle. Officers, as in the rest of the militia, were elected by popular vote.

Most Colonial militia units were provided neither arms nor uniforms and had to equip themselves. Many simply wore their own farmers’ or workmans’ clothes, while others had buckskin hunting outfits. Some added Indian-style touches to intimidate the enemy, even including war-paint. Most used hunting rifles, which did not have bayonets but were accurate at long range. The rifled musket used by most Minutemen was also well suited to this role. The rifling gave it a much greater range than the smoothbore musket, although it took longer to load. When performing as skirmishers, the Minutemen could fire and fall back behind cover before the British could get into range. There is a popular notion that most Minutemen were “crack shots”. In reality, some (with hunting experience) were fine marksmen, while others were poorly trained. (Source: Wikipedia.org.)

Use Quilted Cryo-Paks in Ammo Boxes

Ammunition that heats up well beyond its normal operating can display over-pressure signs. This is true even of powders that are marketed as being temperature “insensitive”. We strongly recommend that ammo be kept under 90° F, and cooler is better–if you can keep things in the 60-80° range, you’ll find your velocities will stay more consistent with nearly all powder choice. We’ve found a versatile, inexpensive new product that helps keep your ammo cool in hot summer conditions. Kryo-Paks are only about 1/4″ thick and come in pleated grids you can cut to fit your ammo box. We keep one in the bottom of a MTM-100 ammo holder and one on the underside of the box-lid. The 8″x8″ CryoPak “Ice Blanket” costs less than $2 at outlet stores like K-Mart and Walmart. Just keep these in the freezer until needed, then put a layer in the base of your ammo box. It’s also not a bad idea to keep your spare ammo in an insulated cooler, out of the sun.

Bases for Pedestal Front Rests

Sinclair Int’l has a new product that can make your front rest more secure, and easier to level on a bench. The Sinclair Superfeet, item 04-190, are 2″-diameter stainless disks with a layer of neoprene on the bottom side. The top dimple holds the rest foot point with no wobble, and the neoprene underside is secure on bench surfaces of concrete, wood or glaze-coated concrete. Your rest won’t shift or slide when you push the rifle forward. Sinclair tells us “With the Superfeet, you don’t need to hammer the rest screws into the bench top. And most shooters find that their speedscrews or elevation cams work better with Superfeet”. Sinclair’s Superfeet come in a set of three for $19.95.

front rest superfeet pad Sinclair

The Sinclair design is similar to the Match Superfeet created by Dave Dohrmann. Dave’s Match Superfeet are also 2″-diameter stainless disks with neoprene on the bottom. But Dave’s Match Superfeet also have spring attachments, which connect the feet to the rest. This makes it easier to pick up the entire rest and reposition it. The spring attachments also ensure that the system is completely legal in IR 50/50, NBRSA and IBS Competition. A set with 3 discs and 3 spring retainers is $29.95, while a set with 3 discs and 2 retainers is $27.95. Contact Dave at (864) 884-0155 or via email dbugholes [at] aol [dot] com to order his Match Superfeet.

Using 6BR Dies to Neck-size 6XC

reloading die spacer ringsCredit German Salazar for this smart tip. 6XC dies tend to be pretty expensive. If you already have a 6BR neck-sizing die, you can use it to neck-size 6XC brass. Redding Reloading sells a set of three washers that raise the die in the press, part number 80901. Each kit includes three spacers: (.062) No-crimp or partial resizing, (.125) 44 Spl/44 Mag spacer, (.135) 38 Spl/357 Mag spacer. If you buy two sets (about $7.00 each at Bruno Shooters Supply) and use both 0.125″ spacers and one 0.135″ spacer then you can neck size 6XC cases with your 6BR neck sie without messing with the lock ring setting. You can also use the same spacers to switch pistol dies (e.g. between .38 Special and .357 Magnum). Hornady also sells inexpensive .135″ spacers to switch from .38 spl to .357.

Suhl 150 Match Rifles at Century Arms

The Suhl 150 is a great rimfire match rifle. This East German 22LR can be as accurate as an Anschütz–you’ll just find the Suhl a bit rougher around the edges. Suhl barrels can be very accurate–some Suhl factory tubes are benchrest competitive. Many Suhl 150s have been converted into succcessful BR and Silhouette guns. Joe Friedrich won the ARA 2006 Grand Agg shooting a Suhl 150 with custom McMillan stock and aftermaket barrel. Florida’s Century Arms recently acquired a supply of the hard-to-find Suhl 150s. Two models are offered–a prone rifle with straight comb, and a position model with adjustable cheek-piece and more vertical pistol grip.

suhl kk 150 22 target rifle

Century Arms has a couple dozen of the Suhl 150s left, with the “dealer” prices running about $610-$630 (Century will not sell direct to individuals, so you’ll have to purchase through your local dealer.) These are used guns, so they vary in cosmetic quality. Most of the rifles include front and rear iron match sights but NOT extra inserts or separate tool kits. If you’re looking for a high-quality smallbore rifle for considerably less money than an Anschütz 54, call Century Arms at (800) 527-1252. These guns will sell out quickly as Suhl 150s are no longer being made and the supply of good, used guns is drying up.

Use 6mm Comparator as Rimfire Gauge

Here’s a great way to use an existing Stoney Point-style bullet comparator to measure smallbore case rim thickness. The Stoney Point tool, now sold by Hornady as the “Lock-N-Load Bullet Comparator“, comes with a red comparator body into which inserts of various calibers can be fitted. If you have a 6mm (.243) insert for the comparator, you can use it as a “poor man’s” rimfire rim-thickness gauge. It works perfectly for 22LR and 17HM2–just drop the rimfire round to be measured in the hole, and then slide the unit against the caliper jaws. For a slightly tighter fit, use the .223 insert and ream VERY slightly. But we think you’ll find the standard 6mm insert is just about perfect. We were able to get repeatable readings to about .0005″. This is an ideal “Zero-Cost” adaptation of a popular tool.

Werner Mehl's Amazing Videos

Germany’s Werner Mehl is the talented engineer who created the PVM-21 infrared chronograph, in many respects the most sophisticated ballistic speed-measuring system currently available to the general public. Werner runs a company, Kurzzeitmesstechnik, which specializes in high-tech ballistic measuring systems and ultra-high-speed photography. Werner has engineered camera and lighting systems that can literally track a bullet in flight, millimeter by millimeter, with eye-popping resolution. Werner employs digital cameras that record up to 1 million frames per second, with effective shutter speeds as fast as 1.5 nano-seconds. The videos produced by Werner’s systems are amazing. Below are two short samples. The first shows a 7mm bullet penetrating cardboard. Note you can clearly see the engraving of the rifling on the bullet. CLICK HERE to watch VIDEO. (Right click and “save as” to download video.)

The second sample shows a lead 22LR bullet hitting a steel silhouette and disintegrating. Below is a low-frame-count version (for quicker page-load). But CLICK HERE to watch the full 1.9 megabyte version with a higher frame rate. It is much more impressive, as it reveals the complete bullet disintegration in great detail.

NEW Redding Case Neck Gauge

Every precision reloader should have a quality tool for measuring case-neck wall thickness. This is essential for those who turn necks–to check the results of your turning. Even if you prefer no-turn necks, a case neck gauge lets you check your neck dimensions and sort cases by neck wall thickness and uniformity. Consistent neck tension is critical for accuracy–but without uniform neck-wall thickness neck tension is hard to control. The new Redding Case Neck Gauge, released in late April, has many notable features. First, it has an integral base. This can be screwed to a bench-top, placed in a vise, or simply held in place with a clamp.

redding caseneck gauge

The pilots are stainless steel with a smart design. First, on the inboard end, the pilot is slightly under-cut so it doesn’t give a false reading based on slight imperfections in the case mouth. On the other end, there is a step-down (i.e. reduced radius). This provides extra clearance around the neck-shoulder junction, where a doughnut may exist.

Redding case neck gauge pilot stopWith this “smart shape”, the pilot ensures you are getting accurate read-outs of the critical area of the neck-wall. The pilot also rides on a shaft with pins on each end that fit in the case flashhole. This keeps the case centured on the pilot. The Redding Case Neck Gauge (item 26400) ships with two pilot stops, #06121, for .22 caliber and #06130, for .30 caliber. If you use this with a 6mm you’ll need to order pilot #06122 for BR style small flashholes, or pilot #06124 for large flashholes (e.g. with 243 Win brass). The new Redding Case Neck Gauge is available from Grafs.com, Midsouth Shooters Supply, and other vendors for about $65.00, including .001″ dial indicator.
