Bargain Finder 80: AccurateShooter’s Deals of the Week

Accurateshooter Bargain Finder Deals of Week

At the request of our readers, we provide select “Deals of the Week”. Every Monday morning we offer our Best Bargain selections. Here are some of the best deals on firearms, hardware, reloading components, and shooting accessories. Be aware that sale prices are subject to change, and once clearance inventory is sold, it’s gone for good. You snooze you lose.

1. Midsouth — Labradar Chronograph and Accessories

Labradar chronograph

Midsouth Shooters Supply is now carrying the advanced Labradar chronograph. This unique unit allows you to measure your shots without having to set up a tripod and skyscreens downrange. When you start using a Labradar, you’ll never want to go back to old-style chronographs. You can also purchase the Labradar from Bruno Shooters Supply. Price is $559.95 from either vendor. NOTE: Very soon Labradar plans to offer Bluetooth functionality, allowing you to control the machine remotely with your mobile device. This functionality will come via new software — the Bluetooth transceiver is built-in to all current Labradar units, so you can buy one now and use Bluetooth later (when the software is released).

2. Natchez — Special 5 Reloading Press Kit, $199.99

RCBS Special 5 Reloading Kit

This RCBS Kit has everything a new reloader needs: single-stage press, powder measure, scale, powder trickler, priming tool, cartridge tray, “rocket” chamfer tool, case lube and more. This is an excellent entry-level reloading kit, on sale for just $199.99 at Natchez Shooters Supplies. We like the relatively compact Special 5 press for most reloading duties. Eventually you may want to add an additional, large heavy press, but this will get the job done. For the combined package, with all the tools one needs to hand-load quality ammo — this is a stunningly good deal at $199.99.

3. CDNN — Browning Maple X-Bolt Medallion, $849.99 with Rebate

Browning X-Bolt Medallion

CDNN Sports has some of the nicest modern Browning rifles we’ve seen. These deluxe Maple-stocked X-Bolt Medallion Rifles are now on sale for $899.99, marked down from $1519.99. Plus, through March 31st, you can get another $50.00 off with a Browning Rebate. The machine-engraved receiver features a polished blued finish, and is glass bedded into the stock. The free-floating barrel is high-gloss blued, hand-chambered and finished with a target crown. The bolt has a 60° lift and the trigger is adjustable. The stock is a high gloss AAA maple with rosewood fore-end and pistol grip cap. These are very nice rifles that any shooter would be proud to own. This Editor has ordered one as a gift to a family member — that should say something.

4. Amazon — Ammo Can/Gun Case/Range Bag System, $44.99

Plano 1612 X2 range bag ammo can gun case

This Plano 1612 X2 Range Bag System combines a plastic ammo can-type container with a two-pistol hardshell case, both enclosed in a durable, padded fabric cover with many pockets. This handy system lets you keep pistols in a separate locked compartment while still accessing ammo, muffs and other gear from the main compartment, which can also be secured with a padlock. This is a clever, versatile design, and owner reviews have been very positive:

The perfect range bag. It comes with a nice gun case, more pockets than shown, plenty of storage for earphones, several boxes of ammo and room to spare. Would buy again!” — Nate K

The problem with most range bags is that they are range ‘bags’. This is an ammo can with pockets for all your other gear. No more ‘saggy baggy’!” — MPowers

5. Sportsman’s Guide — 1000 Rds 9mm Ammo, $204.99 delivered

9mm Luger 9x19mm ammo deal case 1000 rounds Sportman's Guide

Everyone can use a 1000-round case of 9mm Luger Ammo. This Sellier & Bellot 124gr FMJ brass-cased ammo feeds and functions well. We’ve checked around and this $204.99/1000 price is one of the best deals on brass-cased 9mm ammo this week (for SG members, the cost is $194.99). Plus you can get FREE shipping with CODE SH2656 at checkout. We have shot this ammo in Glock, H&K, Sig Sauer, and S&W pistols. Rated at 1080 fps, this 9mm ammo was very reliable, and the boxer-primed cases are reloadable.

6. Cabelas — Simmons 20-60x60mm Spotter, $49.99 with Rebate

Simmons Spotting Scope Bargain Cave Cabelas 20-60x60mm

Let’s be realistic — this 20-60x60mm Simmons is NOT a great spotting scope. The sharpness is nowhere near as good as you’d get with a $1000+ spotter. However, you can now get this unit for under fifty bucks with manufacturer’s rebate. Cabela’s Sale Price is $59.99 and Vista Outdoor is offering a $10 Rebate. For basic work, such as viewing pistol targets, or spotting hits out to 250 yards, this bargain basement Simmons should suffice. Read the owner reviews — they have been surprisingly good. This scope will also work for general recreational use. Hard to beat for fifty bucks.

7. Amazon — 34 dB Noise Rating Ear Muffs, $17.45

34dB NRR 32 hearing protection earmuffs

These 34 dB NRR earmuffs provide excellent sound protection without being too heavy and bulky. At at $17.45, they are a great bargain. The lower section of the muff is trimmed for a narrower profile — that helps with rifle and shotgun stocks. The headband is adjustable and has comfortable padding. These Pro For Sho Muffs have earned a 4 1/2 star consumer rating, with over 1,600 Amazon customer reviews. NOTE: These fit pretty tight. If you have a very large hat size you might want a different brand.

8. Amazon — Lyman 50th Edition Reloading Manual, $19.99

Lyman 50th Reloading Manual

Here’s a good deal on the new Lyman 50th Ed. Reloading Manual. Our Forum members have rated this as the best Loading Manual for starting hand-loaders. This 50th Edition, the first to be produced in full color, includes more load data, and covers more cartridges than ever before. New Cartridges Include: 17 Hornet, 6.5 Grendel, 6.5 Creedmoor, 6.5-284, 26 Nosler, 28 Nosler, 300 Blackout, 300 RCM, 338 RCM, 450 Bushmaster, 458 SOCOM, 50 Beowulf. Amazon has the Softcover version for $19.99 and Hardcover for $23.99. Notably, Lyman donates $1.00 to the NRA for every Lyman 50th Edition Reloading Handbook sold during the first year of publication.

9. Amazon — Neiko Digital Calipers, $16.45

Amazon Neiko Digital Caliper

Even if you have a good set of calipers, you may want to get one of these Neiko 01407A Digital Calipers. The #1 best-selling digital caliper on Amazon.com, this Neiko tool features a large LCD Screen and measures up to 6.0 inches. With over 2300 customer reviews, this product has earned an overall rating of 4.4 out of 5 stars. It’s hard to go wrong for $17.74, even if you just use these as a spare set for measuring group sizes and case trim lengths.

PMA Micro-Die Adjuster — Try One And You’ll Be Spoiled

PMA Tool Micro Die Adjuster .001 Shoulder Bump full length sizing lift shim

Wouldn’t it be great if you could quickly and easily adjust shoulder bump during the full-length sizing process, without struggling to move die lock-rings by trial and error (or fiddle with shims). Well you can. The PMA Micro Die Adjuster is a brilliant little device that replaces the lock ring on your FL sizing die. It allows you to move the die up and down in precise, tiny increments. The tool has .001″ index marks, but you can easily set your die between the marks to achieve .0005″ (half-thousandth) adjustments.

The affordable PMA Micro Die Adjuster is offered in two versions, an upgraded model with a handy thumb screw for $69.95 (photo above), as well as the original with set screw for $65.95 (photo below).

PMA Tool Micro Die Adjuster .001 Shoulder Bump full length sizing lift shim

To see how the PMA Micro-Die Adjuster works, watch this video by our friend Boyd Allen:

Many of our Forum members now use the PMA Micro Die Adjuster, and they give this specialty tool high praise. Here are actual reviews by Forum members and other verified tool buyers. Read more comments in this AccurateShooter Forum Thread.

PMA Micro Die Adjuster User Reviews

“No more ‘close enough’ for headspace[.] With this tool set-up it’s easy to put headspace exactly where you want it, then repeat it exactly for subsequent batches for the same cartridge.” — JohnF

“I have four of these Micro Adjuster rings and all I can say is that it works and it is repeatable. I bump my brass .0005″-.001″ and this die lock ring will do it without issue.” — TrapperT

“I size brass for four different 6.5×47 rifles (chambered with three different reamers) using a single die, set in the PMA Adjuster. I have to say… I should have bought one sooner. Adjusting it is very quick and repeatable to well under .001.” — /VH

“I’ve been using PMA’s lock ring for some time now and find it to be very easy to adjust to within .0005″ on a single piece of brass. Very quick to do as well. One thing I have found is that if you still need that half-thou adjustment I will run the brass once more at the same setting before I make that .0005″ adjustment and 50 percent of the time that does the trick. The marked increments are in .001″ scale so if you go half way in between there’s your half-thousandth.

PMA Micro-Adjuster vs. Shims

Many hand-loaders have abandoned shims after trying the PMA Micro Die Adjuster:

“Shims [require] you to completely remove the die. That gets old rather quickly after having used the PMA adjustable lock ring.” — Patch 700

“Great product. Shims used to drive me crazy, put a .002 in and get .0035 of change. With this if you want .0015 set it and that’s what you get.” — John B

“I like mine — adjustments are easy and it will adjust very fine. I used to use .001″ shims. Now can adjust my bump as fine as I want.” — Joe139

PMA Micro die adjusterProduct Description from PMA Tool
The PMA Tool Micro Die Adjuster (MDA) replaces your existing lock ring and can be used with nearly any 7/8-14 full length sizing die. We successfully used this tool with sizing dies from Redding, RCBS, Hornady, Lee, Harrells Precision and those made from Newlon Precision die blanks. It allows you to easily make adjustments to your “shoulder bump” as fine as .0005″. The engraved marks on the MDA are equal to approximately .001 inches (true adjustment .000992″) of adjustment to the shoulder bump. Splitting the engraved marks is therefore approximately equal to .0005″. The design of the MDA does not allow it to work with the Forster Co-Ax press. Some custom dies for very short cartridges may require the use of an extended shellholder. Micro Die Adjuster shown in use installed on Custom Newlon/Scott 6mm PPC Die and Harrells Precision Compact Press.

Chronograph Testing — Tips from the USAMU

USAMU Marksmanship Unit Velocity Chronograph Testing Sample Sizes

Each Wednesday, the U.S. Army Marksmanship Unit publishes a reloading “how-to” article on the USAMU Facebook page. This past week’s “Handloading Hump Day” article, the latest in a 7-part series, relates to chronograph testing and statistical samples. We highly recommend you read this article, which offers some important tips that can benefit any hand-loader. Visit the USAMU Facebook page next Wednesday for the next installment.

Chronograph Testing — Set-Up, Sample Sizes, and Velocity Factors

Initial Chronograph Setup
A chronograph is an instrument designed to measure bullet velocity. Typically, the bullet casts a shadow as it passes over two electronic sensors placed a given distance apart. The first screen is the “start” screen, and it triggers an internal, high-speed counter. As the bullet passes the second, or “stop” screen, the counter is stopped. Then, appropriate math of time vs. distance traveled reveals the bullet’s velocity. Most home chronographs use either 2- or 4-foot spacing between sensors. Longer spacing can add some accuracy to the system, but with high-quality chronographs, 4-foot spacing is certainly adequate.

Laboratory chronographs usually have six feet or more between sensors. Depending upon the make and model of ones chronograph, it should come with instructions on how far the “start” screen should be placed from one’s muzzle. Other details include adequate light (indoors or outdoors), light diffusers over the sensors as needed, and protecting the start screen from blast and debris such as shotgun wads, etc. When assembling a sky-screen system, the spacing between sensors must be extremely accurate to allow correct velocity readings.

Statistics: Group Sizes, Distances and Sample Sizes
How many groups should we fire, and how many shots per group? These questions are matters of judgment, to a degree. First, to best assess how ones ammunition will perform in competition, it should be test-fired at the actual distance for which it will be used. [That means] 600-yard or 1000-yard ammo should be tested at 600 and 1000 yards, respectively, if possible. It is possible to work up very accurate ammunition at 100 or 200 yards that does not perform well as ranges increase. Sometimes, a change in powder type can correct this and produce a load that really shines at longer range.

The number of shots fired per group should be realistic for the course of fire. That is, if one will be firing 10-shot strings in competition then final accuracy testing, at least, should involve 10-shot strings. These will reflect the rifles’ true capability. Knowing this will help the shooter better decide in competition whether a shot requires a sight adjustment, or if it merely struck within the normal accuracy radius of his rifle.

How many groups are needed for a valid test? Here, much depends on the precision with which one can gather the accuracy data. If shooting from a machine rest in good weather conditions, two or three 10-shot groups at full distance may be very adequate. If it’s windy, the rifle or ammunition are marginal, or the shooter is not confident in his ability to consistently fire every shot accurately, then a few more groups may give a better picture of the rifle’s true average.

The Amazing 30 Major — 6.5 Grendel Necked Up to .30 Caliber

30 Major 6.5 Grendel 30 caliber PPC

Sometimes everything comes together — a great barrel, the right load, good bullets, and, of course, a gifted trigger-puller. Check out this target from Forum member Mike Ezell. That’s five (5) shots at 100 yards from Mike’s 30 Major benchrest rifle. When this group was shot a while back, Mike reported: “I fired a few groups in the great weather. No surprises — it did VERY well! My little wildcat, the 30 Major, has always been a shooter. That target was not a fluke — I shot a few groups today and Agg’d a high One.” Mike is a Kentucky gunsmith who builds his own rifles.

30 Major is Based on 6.5 Grendel
What’s a “30 Major” you ask? This is Mike’s own wildcat, a 6.5 Grendel necked up to .30 caliber. Mike writes: “The 30 Major is essentially a .070″-long 30 PPC. With the great 6.5 Grendel brass available from Lapua, all you need to do is neck-up and turn the necks to prep the brass.” Mike says it is very much like a 30 BR, but you just start with 6.5 Grendel brass instead of 6mmBR brass.

The cartridge has one major benefit — it utilizes a PPC-diameter bolt face. That makes it easy to convert your group-shooting 6 PPC to shoot score with .30-cal bullets. Mike explains: “If you have a PPC, to shoot score, all you have to do is chamber up a [.30 caliber] barrel and screw it on your PPC.”

From 7.62×39 Russian to 30 Major — Full Circle

Arms expert Neil Gibson has an interesting perspective on the lineage of the 30 Major. He reminds us that this wildcat has returned to its roots: “Start off with the 7.62×39 Russian [cartridge]. The Russians then modify it, necking it down to .223 for deer hunting. The U.S. benchrest guys then modify that, necking it up to 6mm and blowing the case out making the 6mm PPC. Someone takes that case, necks it out to 6.5 mm, making the 6.5 PPC. Alexander Arms takes that and makes the 6.5 Grendel. Then finally Mike Ezell takes the Grendel and necks it up to 30 caliber, making the 30 Major. From 30 caliber, back to 30 caliber. OK, the original uses .31 caliber bullets, but the bore is still .300. Talk about almost coming round full circle!”

Great Accuracy Restored after Solving Mystery Problem
To get his 30 Major rig shooting this well, Mike had to solve a mysterious problem that cropped up last year. Mike explains: “Two years running, I have finished in the top 15 in IBS points shooting [the 30 Major], but last year’s benchrest season was tough.” Mike was having some accuracy issues that defied explanation. But he figured it out: “The front action screw was bottoming out against the barrel extension – just barely. A simple fix brought the gun back to life. It’s a Stiller Viper Drop Port. The action is screwed and glued into the stock, so I was a bit surprised … especially after having checked for [that issue] while looking for the problem. I’m just glad to have found the trouble so I can begin to re-instill some confidence in the gun and myself, after last year.”

PMA Micro-Adjust Case Trimmer — Precise and Handy

PMA Micro Adjust Case Trimmer

Serious reloaders know that PMA Tool makes some of the best specialty reloading tools you can buy. To help folks get the most out of their PMA products, the company offers “how-to” videos. One such video features PMA’s great Micro-Adjust Case Trimmer. PMA owner Pat Reagin tells us: “We’ve had quite of bit of interest in the case trimmer, but a lot of guys want to see it in action. So we’ve created an intro video that shows how to adjust and use the trimmer in various modes.”

Watch Micro-Adjust Case Trimmer Video

The PMA Micro-Adjust Case trimmer indexes off the shoulder but it also provides precise control over neck length. You aren’t limited to a built-in, neck-length setting like some other shoulder-indexed trimmers. The PMA Micro-Adjust Trimming tool currently sells for $129.95 including one cartridge insert. The inserts, which can be purchased for $13.95 separately, can often work for a multiple cartridge types within the same family. For example, you can use the same insert for both .243 Win and .260 Rem. There is another insert that works with both 7mm-08 and .308 Win.

PMA Micro-Adjust Case Trimmer Features:

  • Indexes off shoulder for easy, consistent trim length.
  • Cases captured in no-scratch, Delrin™ inserts.
  • Fully rotating head with bearing for smooth operation and clean, square cuts.
  • Sharp carbide cutter for quick, smooth cuts with minimal burr.
  • Spring loaded head allows complete control of rate of feed.

How to use the PMA Micro-Adjust Case Trimmer
The trimmer indexes case off the case shoulder through the use of interchangeable Delrin™ inserts which capture the shoulder and neck of the case. This insert is contained in a spring-loaded tool head that rides on a linear bearing. The Micro-Adjust Trimmer can be used in three ways.

PMA Micro Adjust Case Trimmer

First, you can secure the case in a PMA caseholder chucked in a power drill, drill press, or lathe. You hold the trimming tool with your hand and feed in the spinning case. (This method is handy because if you leave the case in the holder, after you have trimmed to length, you can switch tools and chamfer the case-mouth using the same power source).

PMA Micro Adjust Case Trimmer

In the second method, the trimmer’s adjustment knob is removed (after locking the setting) and the cutting shaft is chucked in a drill, drill press. or lathe. Using this method, the case itself is held by hand and fed into the cutter. Lastly, the trimmer can be used manually, holding the case in one hand and the trimmer in the other. That’s the slowest method, but it works if you do not have power tools handy.

Inspecting Your Brass — What Case Flaws Reveal

Case Diagnostics 101 Sierra Bullets .223 Rem 5.56 brass cartridge safety

Ever wondered what caused a particular bulge or marking on a case? And more importantly, does the issue make the case unsafe for further use? Sierra Bullets Ballistic Technician Duane Siercks offers some insight into various issues and their causes in this article from the Sierra Blog.

Incipient Case-Head Separation
This is a Winchester .308 Win case that has a real issue. This case has a very obvious incipient case head separation in the process of becoming a complete failure.

Sierra Case reloading pressure safety inspection

This is most commonly caused by over-sizing the case causing there to be excess headspace on the case. After a few firings and subsequent re-sizing, this case is just about ready to come completely apart. Proper die adjustment is certainly a requirement here. Of course this case is not safe to reuse.

Excessive Pressure (Load Too Hot)
If you will notice in the picture of the case rim, there are two pressure signs to notice. First, look at the primer. It is basically flattened to about the max of what could be considered safe. If this was the only pressure sign noted, I would probably be fine with this load, but would constantly keep an eye on it especially if I was going to use this load in warmer temperatures. This load could easily cross into the “excess pressure” realm very quickly.

Sierra Case reloading pressure safety inspection

There is another sign of pressure that we cannot ignore. If you’ll notice, there is an ejector mark apparent that is located over the “R” of the R-P headstamp. This absolutely tells us that this load would not have been in the safe pressure range. If there were any of these rounds loaded, they should not be fired and should be dis-assembled. This case should not be reloaded.

Split Case-Neck
Here we have an R-P .22-250 case that has died the death. Everything looks fine with this case except the neck is split. This case must be tossed.

Sierra Case reloading pressure safety inspection

A split neck is a normal occurrence that you must watch for. It is caused by work-hardening of the brass. Brass cases get harder with age and use. Brand new cases that are stored for a period of time can become hard enough that they will split like this case within one to two firings. I have had new factory loads do the same thing. Then as we resize and fire these cases repeatedly, they tend to get harder and harder. Eventually they will split. The life of the case can be extended by careful annealing practices. This is an issue that would need to be addressed in an article by itself. Of course this case is no longer usable.

In the classes that I teach, I try to use examples like this to let the students see what they should be looking for. As always, if we can assist you, whether you are new to reloading or very experienced, contact us here at Sierra Bullets by phone at 1-800-223-8799 or by email at sierra@sierrabullets.com.

Dented Case Body
Here we have a Lake City 7.62×51 (.308 Win.) case with two heavy marks/dents in the case body.

This one may be a bit of a mystery. It appears as if this case may have been caught in the action of a semi-auto rifle when the firearm jammed or the case failed to clear during the cycling process. I probably would not reload this case just to prevent any feeding problems. This also appeared to be a factory loaded round and I don’t really see any pressure issues or damage to the case.

It is very important to observe and inspect your cases before each reloading. After awhile it becomes second nature to notice the little things. Never get complacent as you become more familiar with the reloading process. If ever in doubt, call Sierra’s Techs at 1-800-223-8799.

The Great Debate — Weight vs. Volume in Powder Dispensing

Lee Auto-Disk Chargemaster weight vs. Volume

When we first ran this story a while back, it spurred a hot debate, with strong opinions on both sides of the issue. Some guys argued vehemently that volumetric powder dispensing was best — citing the experience of short-range benchresters, most of whom still throw their charges. Others say weighing your charges is best, so long as you have a very precise, and very repeatable scale. We know some of the top 1000-yard shooters weigh their charges to the kernel.

Lee Auto-Disk Chargemaster weight vs. VolumeMost competitive long-range shooters weigh powder charges for their handloads. Some even use ultra-precise magnetic force restoration scales to load to single-kernel tolerances. But is weight-based measuring always the best way to fill a case with powder? Another option is volumetric charging. This method fills a precisely-sized cavity with powder and then dumps the charge into the case. A Harrell’s rotary powder measure works this way, as does the sliding powder filler on a Dillon progressive press.

For long-range applications, most people believe that precise weighing of powder charges is the best way to achieve optimal accuracy and low ES/SD. However, those short-range Benchrest guys do pretty darn well with their thrown charges, at least at 100 and 200 yards.

Our friend Dennis Santiago recently observed something that made him scratch his head and wonder about weighing charges. His AR-15 match rifle shot better with volumetric (cavity-measured) charges than with weighed charges dispensed by an RCBS ChargeMaster. Here’s what he reports:

Cavity vs. Dribble (Dennis Santiago Report)
I had the chance to compare nominally identical ammunition loaded two ways. These were all .223 Remington match loads using 77gr Sierra Match Kings over 23.4 grains of Hodgdon Varget. Same gun. However I loaded some ammo with charges dispensed with a Lee cavity-style powder measure while other rounds were loaded with powder weighed/dispensed by an RCBS Chargemaster. The cavity-drop ammo (with powder dropped from the Lee unit) was consistently better than the weighed-charge ammo. I have no idea why…

So, ladies and gentlemen — what do you think? Why did Mr. Santiago’s volumetrically-charged ammo shoot better than ammo filled with weighed charges? What’s your theory? Gary Eliseo suspects that Dennis’s Chargemaster might have been drifting. What do you think? Post your theories in the comments area below.
