Inside Chamfer Tools — Sorting Through the Options

There are a wide variety of reloading tools designed to cut a slight chamfer in case necks and deburr the edge of the case mouth. You don’t need to spend a lot of money for an effective tool. A basic “rocket-style” 45° chamfering tool, such as the Forster, actually does a pretty good job taking the sharp edge off case mouths, particularly if you use a little scotch-pad (or steel wool) to smooth the edge of the cut. The Forster chamfer tool, shown below, is a nicely-made product, with sharper cutting blades than you’ll find on most other 45° chamferers. It costs $17.99 at Brownells.com.

Redding sells a handy piloted chamfering tool with a 15° inside cutting angle and removable accessory handle. This Redding Model 15-P chamferer works really well, so long as you have consistent case OALs. The pilot rod (which indexes in the flash hole) is adjustable for different cartridge types (from very short to very long). This ensures the concentricity of the inside neck chamfer to the case mouth. This quality tool works with cases from .22 to .45 Caliber.

Sinclair International offers a 28° carbide chamferer with many handy features (and sharp blades). The $29.99 Sinclair Carbide VLD Case Mouth Chamfering Tool will chamfer cases from .14 through .45 caliber. This tool features a removable 28° carbide cutter mounted in the green plastic Sinclair handle. NOTE: A hex-shaft cutter head power adapter can be purchased separately for $14.99 (Sinclair item 749-002-488WS). This can be chucked in a power screwdriver or used with the Sinclair Case Prep Power Center when doing large volumes of cases.

Many folks feel they can get smoother bullet seating by using a tool that cuts at a steeper angle. We like the 22° cutter sold by Lyman. It has a comfortable handle, and costs just $10.75 at MidsouthShooterssupply.com. The Lyman tool is an excellent value, though we’ve seen examples that needed sharpening even when new. Blade-sharpening is easily done, however.

K&M makes a depth-adjustable, inside-neck chamferer (“Controlled Depth Tapered Reaper”) with ultra-sharp cutting flutes. The latest version, which costs $47.00 at KMShooting.com, features a central pin that indexes via the flash hole to keep the cutter centered. In addition, the tool has a newly-designed handle, improved depth-stop fingers, plus a new set-screw adjustment for precise cutter depth control. We caution, even with all the depth-control features, if you are not careful, it is easy to over-cut, slicing away too much brass and basically ruining your neck. We think that most reloaders will get better results using a more conventional chamfer tool, such as the Forster or Redding 15-P.

One last thing to note — tools like the K&M and the Sinclair chamferer are often described as VLD chamferers. That is really a misnomer, as bullets with long boat-tails actually seat easily with very minimal chamfering. In reality, these high-angle chamferers may be most valuable when preparing brass for flat-base bullets and bullets with pressure rings. Using a 22° or 28° chamferer can reduce the risk of cutting a jacket when using VLD bullets though — so long as you make a smooth cut.

Affordable and Reliable — Sightron SIII 10-50x60mm Comp Scope

Sightron Scope 10-50x60mm SIII SS scope James Mock long range competition review MOA MOA-2 reticle

Many of our Forum members who shoot F-Class and Long Range Benchrest have asked: “Is there a reliable high-magnification (at least 45X) zoom scope under $1100?” The answer is yes — the Sightron SIII 10-50x60mm scope will do the job, and you can buy one now for under $1000.00. In fact, at the 2017 IBS 600-yard Nationals, 4 of the Top 10 shooters (including the 2nd-place finisher) used Sightron 10-50X scopes. Though reasonably priced, this 10-50x60mm optic is definitely good enough to win long-range benchrest and F-Class matches. Here is a review by James Mock. Note James tested a version with 1/4-MOA clicks. Sightron also offers versions of this scope with 1/8-MOA clicks.

Sightron 10-50x60mm Riflescope Field Test
Review by James Mock
Mr. Allen Orr of Sightron was kind enough to loan me one of their fine SIII riflescopes for testing. Since I shoot 600-yard score matches more than anything else, I requested the 10-50x60mm model with MOA-2 reticle. This is a premium scope in every way and it may be the very best buy for a long range scope today. Real world price for this scope is around $1000 ($999.97 on Amazon.com). This represents a good value considering the scope’s build quality and features: 50X max magnification, 1/4-MOA adjustments with 10 MOA per revolution, ExactTrack windage and elevation system, Zack-7 lens coating, 60mm objective lens, target knobs with zero stop, and lifetime warranty. The MOA-2 reticle’s hash marks span 2 MOA at 24X and 1 MOA at 48X. Eye Relief is ample: 4.5″ at 10X and 3.8″ at 50X. Field of view at 100 yards is 9.6′ at 10X, 2.2′ at 50X.

NOTE: Sightron also offers this scope with 1/8-MOA clicks with a Fine Cross-Hair Reticle, Target Dot Reticle, and Mil-Dot Reticle. There are also multiple Sightron SIII 10-50x60mm models with illuminated reticles.

Sightron SIII 10-50x60mm Shows Excellent Repeatability
After receiving the scope, I mounted it on my BAT 6mm Dasher and did my “standard tests”. I shot the “square” and the adjustments were spot on and the repeatability was faultless. I also shot a group at two powers (24X and 50X) and the point of impact was the same.

In our August 600-yard match, I used the scope and was favorably impressed. I did not have the opportunity to shoot 600 yards prior to the match but I do have a 100-meter range at my house. From past experience, after zeroing my Dasher at 100 I simply dial up 11 MOA to shoot at 600 yards. The weather in Louisiana has been something that I have never seen before and the August 20th match was moved to August 27th, but there was still standing water in front of the targets. Also, the fog was so heavy that the start of the match was delayed for 45 minutes.

Sightron Nails a 50 Score on First-ever Match Target
When the match started, the Sightron with 11 MOA dialed in was perfect for elevation and a little right. After a couple of clicks I was ready to shoot. My first target was a pleasant surprise — scoring a 50-1X. I was very impressed with this scope and I shot it at 48X all day in the heavy mirage. I ended up finishing third, two points behind the winner.

With its 60mm objective lens, this is a large scope. It is 16.9″ long and weighs 30.1 ounces. If you can tolerate that weight in the discipline you shoot this scope represents a great value for the long-range shooter. I am favorably impressed with it. For you varmint shooters, this scope with its wide range of power would make a superb addition to you favorite prairie dog rig. Do note, as we explained above, there are other versions of this scope with 1/8-MOA clicks if that is your preference.
Good shooting — James Mock

[Addendum: When we first published this review, a couple readers who owned the scope had one complaint. They both said that the side parallax control (side focus), was hard to manipulate — it required a lot of effort to rotate. One fix is to attach something to provide more leverage. However, if you send the scope back, Sightron will modify the side focus to make it easier to rotate.]

New STREAK Ammo with Glowing Phosphorescent-Base Bullets

Streak Phosphor glowing visual ammunition non-flammable

Wouldn’t it be cool if you could see a streak of light following your bullets into the target — like a tracer round, but without the fire risk. Now this is a possible with the new STREAK line of “visual ammunition”. STREAK ammo is something completely new — it is NOT a conventional tracer. Instead, it employs a glowing bullet base to create an “illuminated, non-incendiary projectile”. These rounds are fun to shoot, particularly in indoor ranges (where most handgun shooting is done).

STREAK’s patented formulation incorporates a non-flammable phosphor material that utilizes the light emitted during discharging of the round to make STREAK glow. The manufacturer states: “STREAK is not on fire and does not generate heat, therefor making STREAK safe for indoor range use where the illumination is best seen.”

Video has loud, annoying music track — you may want to turn down speakers before playback.

STREAK Ammo Popular with Shooters
“STREAK adds a whole new dynamic to target shooting,” said Bren Brown, of the Frontier Justice Range in Kansas City. “Our clients loved it so much that we have decided to do a weekly STREAK Shooting night at our ranges.”

STREAK ball ammunition is currently available in 9mm Luger, .40 S&W, and .45 ACP in both red and yellow/green illumination colors. In the near future it will be offered for other pistol and rifle calibers, and with hollowpoint bullet types.

Optimal Conditions for STREAK Ammo Sessions
STREAK ammunition is intended for use in areas free of natural sunlight when the human eye pupil is most open. Dusk-till-dawn and indoor lighting permits the pupil to open enough to see STREAK ammunition. Contrast is what permits you to see a glowing object moving at the speed of a bullet. The darker the backdrop and target the better you’ll see STREAK.
