Shootin’ in the Snow — It Just Takes Commitment…

December Snow White Christmas Weather Channel Storm Decima
Weather Forecast for 12/16/2016 from The Weather Channel.

The Rockies, Great Lakes, and Northeast are bracing for a major storm this weekend, bringing cold winds, ice, and plenty of snow. Many Northern states have already seen lots of the white stuff. It seems like it will be a White Christmas for many. Does that mean there will be no more gun fun ’til spring? Heck no — just grab your snow shovel, load up your rifle, and go shooting. Here’s how Forum Member Nick (aka “ChevyTruck 83″) coped with winter’s fury back in 2012. Never underestimate the resourcefulness of a dedicated AccurateShooter Forum member….

December Snow White Christmas Weather Channel Storm Decima

snow shooting range snowmanWe admire the fortitude of Forum Member Nick who braved wintry December weather to enjoy a day at the range in his native Pennsylvania. A little snow on the ground couldn’t stop this intrepid shooter, who brought snow shovel and arctic gear to his range session. Folks, here’s a true “hardcore” fan of shooting! Despite the “relentless snow”, Nick reports that “at least it wasn’t windy”. Nick shot a variety of long guns, including his .22LR rimfires, a .223 Rem, and a .308. Not daunted by the cold, Rick said it was fun to “play like a kid once in a while.” That’s the spirit!

December Snow White Christmas Weather Channel Storm Decima

Nick reports: “There was no wind to speak of — just relentless snow. I’ll tell you what — it’s awesome to get out and play like a kid once in a while.”

Nick’s foray into the winter wonderland really puts things in perspective for “fair-weather” shooters. After viewing Nick’s Forum thread about his snowy range session, fellow Forum member DennisH observed: “I will never complain about our super hot sugar cane fields in south Louisiana ever again! We can hold matches 12 months a year. I have NEVER had, owned, or used a snow shovel.”

Bargain Finder 60: 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 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. Amazon — Howard Leight Electronic Muffs, $26.99

AccurateShooter Deals of the Week Muffs hearing protection Howard Leight earmuffs sale bargain

Act quickly — this is a DEAL of the DAY on Amazon! We’ve never seen a lower price on these popular electronic muffs, which are Amazon’s #1 seller in the category. The price goes back up tomorrow! Every shooter should own a pair of electronic muffs, even if you prefer shooting with earplugs and/or standard muffs. Electronic muffs are great when you are doing spotting duties or are working near the firing line. They allow you to hear ordinary conversations while still providing vital hearing protection. Right now Amazon.com has the Howard Leight Impact Sport Electronic Muffs on sale for just $26.99 (Deal of the Day). See All Price Options. NOTE: For regular, sustained shooting we recommend muffs and/or earplugs with a higher NRR rating.

2. CDNN Sports — Ruger American Ranch Rifle (Tan), $349.99

Ruger American Ranch Rifle 5.56 .223 223 Remington Varmint Bolt Action

Here’s a nice little varmint rifle from Ruger with good features and performance at a killer price: $349.99. You could pay that much just for a barrel. This .223 Rem rifle features a 16.5″ hammer-forged barrel barrel threaded 1/2″-28 at the muzzle for brake or suppressor. The action, which features a 70° three-lug bolt, and Picatinny-style scope rail, sits in an aluminum bedding block. The crisp trigger adjusts down to 3 pounds. With a weight (before optics) of 6.1 pounds, this is a handy carry-around varminter. We like this rifle. For $349.99 it’s a steal.

3. Amazon — Caldwell Long Range Target Cam System, $329.49

Amazon Caldwell Precision Long Range Target System Cam Camera

Forum members have purchased this Caldwell Target Cam System and they’ve found that it works reliably, providing a clear signal to any WiFi-enabled mobile device (smartphone, iPad, Laptop). One member specifically tested the unit at 1000 yards and it functioned fine. NOTE: This system does NOT have a zoom camera lens, so you need to position the camera within 10 yards or so of the target. But if you place it to the side a bit, this shouldn’t be a problem. This system comes with a nice, fitted carrying case that holds camera, transceivers, antennas, and stands. You get a very capable system for under $330.00 (Amazon price includes free shipping for Prime members). You can also get this system from Midsouth for $357.02 (shipping extra).

4. Amazon — Cotton Cleaning Patches, 800 for $8.99 – $17.99

Amazon bulk pack patches 800 cotton flannel

Got patches? Here’s a great deal on 100% cotton flannel patches. There are many sizes available, starting at $8.99 for 800 one-inch “17 Cal” patches. For 6mm rifles, we actually like the 1.25″ round “22/223″ sized patches priced at $11.99 for 800. Choose either round patches or square patches in most sizes. We generally like round patches for use with spire-tip jags, but some shooters prefer to wrap their patches around a jag or brush and square patches work better for wrapping. The large, 2″-square .30 Cal patches cost $17.99 for 800.

5. Amazon — Frankford Quick-N-EZ Case Tumbler, $34.99

Amazon Frankford vibratory case cartridge brass tumbler Quick n EZ

Look no further for a great deal on a reliable tumbler. We’ve used this very same machine to tumble both pistol brass and rifle cases. We like the see-through, transparent top and the large capacity — this will hold up to 350 .223 Rem cases. With 1000+ customer reviews on Amazon.com, this Frankford Quick-N-Easy Case Tumbler has earned a 4.5-star rating. If you need a tumbler, you might want to order soon — this is the best price we’ve seen in a while.

6. CDNN Sports — 45 ACP Ruger American Pistol, $399.99

Ruger American Pistol .45 ACP 45 Modular Low Bore Axis Sale

At $399.99, this modern .45 ACP Ruger American Pistol costs hundreds less than premium polymer handguns from Europe. Compared to a Glock 21, it has better sights, a better trigger, and better ergonomics. Compared to an HK USP it has a lower bore axis and is way less expensive. FYI the Ruger’s low bore axis really does reduce felt recoil. The Ruger American pistol has interchangable grip panels so you can adjust the grip to your hand size. Controls are ambidextrous. Bottom line, this is a very good gun that gives up little to Glock, HK, and Walther. Buy American and save hundreds.

7. Amazon.com — RCBS Rockchucker Supreme Press, $126.99

Amazon.com Amazon RCBS Rock Chucker Supreme Single Stage Reloading Press Sale

The RCBS Rock Chucker remains a classic — a big, strong, versatile press that can handle most reloading chores with ease. And now you can get a genuine Rock Chucker Supreme for $126.99 — a very good deal. The Rock Chucker offers plenty of leverage for case-sizing and the “O” is tall enough for long cartridges. The Rock Chucker has a very strong base and should last a lifetime. We’re not fans of the Rock Chucker’s priming system but most serious reloaders use a separate priming tool.

8. RCBS — Buy Green, Get Green Rebate

RCBS Reloading Press Rebate Green

RCBS is running a very attractive Rebate Program currently. If you spend $300.00 on qualifying products you get a $75.00 rebate. Spend $50 and get a $10.00 Rebate.

9. Bullets.com — Norma .22LR Ammo (Match 22 & Tac 22)

Norma Match 22 Tac .22 LR Ammo rimfire ammunition bullets.com

Need quality .22 LR rimfire ammo at an affordable price? Consider Norma. Most folks think Norma only produces centerfire ammo and cartridge brass. As a result, people haven’t been looking for Norma rimfire ammo. Their loss is your gain. Accurate, reliable Norma .22 LR ammunition is in-stock right now at leading online vendors. This is good quality ammo, made in Europe. Bullets.com has Norma Tac-22 ammo in stock at $5.25 per 50-rd box (SKU: BL7819).

Recoil Comparison .223 Rem vs. 6BR vs. .308 Win

6mmBR NormaMany visitors to the site ask us, “I’ve got a .223 and .308. What will a 6mmBR Norma (6BR) give me that I’m not getting already?” Well first you will probably average consistently smaller groups than your current .223 or .308 rifle (assuming the 6BR has a quality barrel and trigger). A good .308 Winchester can be superbly accurate, no question about that, but the lesser recoil of the 6BR works in the shooter’s favor over a long string of fire. Even with a Rem 700 or Savage action factory action, a 6BR with a benchrest stock, premium barrel, and a high-quality chambering job should deliver 5-shot groups in the high twos to mid-threes, provided you do your job. We have one 6BR rifle that shoots Lapua factory-loaded 6BR ammunition in the low twos and high ones. That’s exceptional, we admit, but it still shows how the 6BR is an inherently accurate cartridge, even with factory loads.

Compared to a .223, the 6BR offers a much better selection of high-BC projectiles, and will deliver considerably more power on the target. Compared to the .308 shooting 168gr MatchKings, a 6BR shooting 105-107gr bullets offers better ballistics all the way out to 1000 yards. Plus, for most people, the 6BR is just easier to shoot than a .308. Recoil is less than half of the .308 cartridge. Both the .308 and 6BR chamberings offer good barrel life, but the 6BR uses 15-18 grains less powder, saving you money. On the other hand the .308 is the designated cartridge for F-TR and Palma shooting, so it may be a more versatile chambering for Long-Range competition. So which would we choose between the 6BR and the .308? Actually we think you should have both. The 6BR is my favorite cartridge out to 500 yards, and I like the .308 Win for F-TR. And… if you want to shoot at the World Fullbore Championships this week at Camp Perry there’s only one choice — a .308 Win.

Case Diagnostics — How to Spot Problems with Cartridge Brass

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.

Diagnosing Problems with Cartridge Brass

by Duane Siercks, Sierra Bullets
I was handed a small sample of .223 Rem cases the other day and was asked if I could comment on some marks and appearances that had been noticed as they were sorting through the cases. I will share what was observed and give you what would seem to be a cause for them. These were from an unknown source, so I have no way of knowing what type of firearm they were fired in or if they were factory loaded or reloaded ammunition.

Example ONE: Lake City 5.56, Unknown Year
Case #1 was seen to have a very rounded shoulder and split. Upon first look it was obvious that this round had been a victim of excess pressure. The firearm (perhaps an AR?) was apparently not in full battery, or there was possibly a headspace issue also. While taking a closer look, the primer was very flat and the outside radius of the primer cup had been lost. High pressure! Then I also noticed that there was an ejector mark on the case rim. This is most certainly an incident of excessive pressure. This case is ruined and should be discarded. See photo below.

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

Example TWO: Lake City Match 1993
Case #2 appears very normal. There was some question about marks seen on the primer. The primer is not overly flattened and is typical for a safe maximum load. There is a small amount of cratering seen here. This can be caused by a couple of situations.

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

Cratering is often referred to as a sign of excess pressure. With safety in mind, this is probably something that should make one stop and really assess the situation. Being as there are no other signs of pressure seen with this case, I doubt that pressure was unsafe. That leads us to the next possibility. This can also be caused by the firing-pin hole in the bolt-face being a bit larger than the firing-pin, and allowing the primer to flow back into the firing-pin hole causing the crater seen here. This can happen even with less-than-max pressures, in fact it has been noted even at starting loads. Always question whether pressure is involved when you see a crater. In this situation, I lean toward a large firing-pin hole. This case should be safe to reload.

Example THREE: R-P .223 Remington
Case #3 appears normal with one exception. There are two rings seen about one half inch below the base of the shoulder. These rings are around the circumference of the case, one being quite pronounced, and the other being noticeably less.

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

As we do not know the origin of the firearm in which this case was fired, it does seem apparent that the chamber of the firearm possibly had a slight defect. It could have been that the reamer was damaged during the cutting of this chamber. I would suggest that the chamber did have a couple of grooves that imprinted onto the case upon firing. This firearm, while maybe not dangerous should be looked at by a competent gunsmith. In all likelihood, this case is still safe to use.

Example FOUR: R-P .223 Remington
Case #4 has no signs of excess pressure. There is a bulge in the case just ahead of the case head that some might be alarmed by. This bulge is more than likely caused by this case being fired in a firearm that had a chamber on the maximum side of S.A.A.M.I. specifications. There is actually no real issue with the case. Note that the primer would indicate this load was relatively mild on pressure.

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

If this case was reloaded and used in the same firearm numerous times there might be a concern about case head separation. If you were going to use this case to load in an AR, be sure to completely full-length re-size to avoid chambering difficulties. This case would be safe to reload.

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.

Eye in the Sky — Drone Video of 1122-Yard AR15 Shooting Session

Texas .223 Rem Drone Video 1000 Yards Gorilla Ammo

Many of our readers have never had a chance to shoot much past 600 yards. How far away does a 1000-yard+ target really seem to the naked eye? Well this short video answers that question. Gorilla Ammo, the video’s producers, used a camera-carrying aerial drone to fly downrange from the firing line all the way out to 1122 yards (and back again). Watch the drone footage at 0:00-0:07 and especially 0:48-1:03. The “bird’s-eye view” really gives you a sense of the distance. The “fly-back” at 0:48-1:03 time-mark is what makes this video worth watching.

The video features prone shooting at steel targets placed at 750 and 1122 yards. We do apologize for the lame, “oh so serious” voice-over which attempts to make this rather ordinary range session seem like some kind of life-changing experience. (Frankly, you may just want to turn the sound off — it’s that annoying.) It’s really not that big a deal to hit steel at 750 yards with a quality AR-15, chambered in .223 Rem, shooting Sierra 77 grain MatchKings.

Texas .223 Rem Drone Video 1000 Yards Gorilla Ammo

Hitting Steel at 1122 Yards with 2540 FPS Ammo Can Be Challenging
The 1122-yard hits are a bit more impressive. Gorilla Ammo lists a relatively sedate 2540 fps Muzzle Velocity for its .223 Rem 77gr SMK ammunition. According to JBM Ballistics, at 1125 yards, that 2540 fps load has 68.3 MOA of drop from a 100-yard zero (firing at sea level and 80° F ambient). Morever the bullet goes trans-sonic around 750 yards (losing stability) and is traveling just 933 fps at impact. And the wind’s the killer — at 1125 yards, with this bullet/load, a mere 2 mph, full-value wind change can move the Point of Impact over three feet!

Awesome Deal on Howa 1500 Mini Action Rifle in .223 Rem

Howa Mini Action 1500 .223 Remington Rem Cabelas Bargain 16Stalkup code

Here is a great deal on a great little rifle. Right now at Cabela’s you can get the Howa 1500 Mini-Action in .223 Rem for just $314.99 with Coupon Code 16STALKUP. The rifle (with black synthetic stock) is already on sale, marked down to $349.99. That discount code gives you another 10% off. That’s a bargain — other vendors are charging $515.00 or more for this rifle. We actually “walked through” the online ordering process ourselves to confirm that the discount code works (see below). Note, you order online, but the rifles must be picked up in a Cabela’s store.

Howa Mini Action 1500 .223 Remington Rem Cabelas Bargain 16Stalkup code

The Howa 1500 Mini Action is nearly an inch shorter than a Rem 700 short action, making for a nice, compact carry-around varminter (OAL length is just 41.5″). Your Editor checked out the Howa Mini Action Rifle at SHOT Show. The bolt opens and closes VERY smoothly (way better than most mass-produced bolt guns). The two-stage HACT trigger is excellent — it’s plenty light, with a crisp release and no annoying spring-loaded blade in the middle. I like it MUCH better than standard Remington, Ruger, or Savage triggers.

The standard Howa Mini Action rifle weighs 6 pounds without scope. This particular model comes with a 22″ barrel, black synthetic stock, and 10-round detachable box magazine. The Howa Mini on sale at Cabelas.com is a .223 Remington, but other chamberings are available at a higher price if you shop around. Howa offers Mini Action rifles in .204 Ruger, .222 Rem, .223 Rem, 6.5 Grendel, and 7.62x39mm.

Sling Shooter vs. Mechanical Rest — Man vs. Machine

Man versus machine USAMU AR15 M16 High Power National Record

Can a human, with a sling, shoot as well as a mechanical rest? The answer is “yes” (at least once in a great while) IF that sling shooter can deliver a record-breaking performance. Here’s an interesting tale of man vs. machine from our archives…

The USAMU posed an interesting challenge — could one of their shooters match the performance of a mechanical rest? Who would win in this battle between man and machine? You might just be surprised. At 600 yards, with an AR-platform rifle, the results can be remarkably close, based on targets provided by the USAMU. When clamped in a test rig, a USAMU M16A2 produced a 200-18X group with handloads. The USAMU says this was “one of our better 20-shot groups at 600 yards, testing ammo from a machine rest”. Can a human do better?

Man versus machine USAMU AR15 M16 High Power National Record

Remarkably, a human soldier came very close to matching the group shot from the machine rest. The photo below shows a 20-shot group shot by a USAMU marksman with sling and iron sights, using USAMU-loaded ammunition. The score, 200-16X, was nearly the same. As you can see, the USAMU rifleman didn’t give up much to the machine rest, even at 600 yards!

In fairness, this was no ordinary human performance. The 200-16X score was a new National Record set in December, 1994. This was fired by PFC Coleman in an Interservice Match at Okeechobee, Florida. Brilliant Performance.

Barrel Length and Velocity in a .223 Rem — Barrel Cut-Down Test

.223 Rem Cut-Down Test barrel UMC m855

We often receive questions from varmint hunters and AR shooters regarding barrel length. They want to know how much velocity they will loose if they run a shorter barrel in their .223-Rem rifle. Our friends at Rifleshooter.com did a test that provides some surprising answers to that question.

With barrels, one always wonders “Can a little more length provide a meaningful velocity gain?” To help answer that question, Rifleshooter.com performed an interesting test, cutting the barrel of a .223 Rem rifle from 26″ all the way down to 16.5″. The cuts were made in one-inch intervals with a rotary saw. At each cut length, velocity was measured with a Magnetospeed chronograph. To make the test even more interesting, four different types of .223 Rem/5.56 ammo were chron’d at each barrel length.

READ RifleShooter.com 5.56/.223 Barrel Cut-Down Test Article.

Test Barrel Lost 25.34 FPS Per Inch (.223 Rem Chambering)
How much velocity do you think was lost, on average, for each 1″ reduction in barrel length? The answer may surprise you. The average speed loss of the four types of .223/5.56 ammo, with a 9.5″ shortening of barrel length, was 240.75 fps total (from start to finish). That works out to an average loss of 25.34 fps per inch. (See inch-by-inch data HERE.)

5.56/.223 Barrel Cut-Down Speed Test 26″ to 16.5″ Start FPS at 26″ End FPS at 16.5″ Total Loss Average Loss Per Inch
UMC .223 55gr 3182* 2968 214 22.5 FPS
Federal M193 55gr 3431 3187 244 25.7 FPS
Win m855 62gr 3280 2992 288 30.3 FPS
Blk Hills .223 68gr 2849 2632 217 22.8 FPS

*There may have been an error. The 25″ velocity was higher at 3221 fps.

Rifleshooter.com observed: “Cutting the barrel from 26″ to 16.5″ resulted in a velocity reduction of 214 ft/sec with the UMC 223 55-grain cartridge, 244 ft/sec with the Federal M-193 cartridge, 288 ft/sec with the Winchester M855 cartridge and 217 ft/sec with the Back Hills 223 68-grain match cartridge.”

How the Test Was Done
The testers described their procedure as follows: “Ballistic data was gathered using a Magnetospeed barrel-mounted ballistic chronograph. At each barrel length, the rifle was fired from a front rest with rear bags, with five rounds of each type of ammunition. Average velocity and standard deviation were logged for each round. Once data was gathered for each cartridge at a given barrel length, the rifle was cleared and the bolt was removed. The barrel was cut off using a cold saw. The test protocol was repeated for the next length. Temperature was 45.7° F.”

Much Different Results with 6mmBR and a Longer Barrel
The results from Rifleshooter.com’s .223/5.56 test are quite different than the results we recorded some years ago with a barrel chambered for the 6mmBR cartridge. When we cut our 6mmBR barrel down from 33″ to 28″ we only lost about 8 FPS per inch. Obviously this is a different cartridge type, but also our 6mmBR barrel end length was longer than Rifleshooter.com’s .223 Rem start length. Velocity loss may be more extreme with shorter barrel lengths.

Cost Per Round by Cartridge Type: .223, 6BR, 6XC, .308, 6.5-284

Shooting Cost by Cartridge Caliber type USAMU

Estimating Actual Cost per Round by Caliber
This article comes from the USAMU, which provide shooting and reloading tips on its Facebook Page. This week’s USAMU TECH TIP outlines a ballpark-estimate method of calculating the actual cost per round of different calibers. Some applications, and some shooters, by virtue of their high level of competition, require the very best ballistic performance available — “Darn the cost, full speed ahead!

If you are in serious contention to win a major competition, then losing even a single point to inferior ballistic performance could cost you a national title or record. However, this “horsepower” does come at a cost! Some calibers are barrel-burners, and some offer much longer barrel life. Look at this comparison chart:

Estimated Cost Per Round by Cartridge Type

Below are some estimated total expense per round (practice and competition) based on component costs, type used, expected barrel life and a standard, chambered barrel cost of $520.00 across calibers.

5.56x45mm: $0.46/round (barrel life 6,000 rounds)*

6mmBR: $0.81/round (barrel life 2800 rounds)

6XC: $0.97/round (barrel life 2200 rounds)

.308 Win: $0.80/round (barrel life 4500 rounds)

6.5-284: $1.24/round (barrel life 1100 rounds)

*Note the high round count estimate for 5.56x45mm. This is a bit deceptive, as it assumes a period of “lesser accuracy” use. The USAMU says: “Much of the difference you see here between 5.56 and .308 is due to using the 5.56 barrel for 100-200 yard training with less-expensive, 55gr Varmint bullets after its long-range utility is spent”.

Moreover, while some applications require specialized, high-cost components, others do not. And, if the shooter is still relatively new to the sport and hasn’t refined his skill to within the top few percentile of marksmen, a more economical caliber choice can help stretch a limited budget. Translation: More skill per dollar!

In this post, the prices for all items mentioned here were taken from a major component supplier’s current advertisements, and all brass was of top quality, except in the case of 5.56mm. There, 200 top-quality, imported cases were reserved for 600-yard shooting, and the other brass used was once-fired Lake City surplus.

Cartridge cases were assumed to be loaded 10 times each. [Your mileage may vary…] Bullet prices assumed the use of less-expensive, but good-quality match bullets for the bulk of shooting as appropriate.

The cost of top-tier, highly-expensive match bullets was also calculated for a realistic percentage of the shots fired, based on ones’ application. Barrel life by caliber was taken from likely estimates based on experience and good barrel maintenance.

Brass Costs Based on 10 Loads Per Case
Often, handloaders may calculate ammunition cost per round by adding the individual costs of primers, powder charges and projectiles. Many don’t consider the cost of brass, as it is reloaded several times. Here, we’ll consider the cost of enough top-quality brass to wear out a barrel in our given caliber, at 10 loads per case, except as noted above.

Don’t Forget Amortized Barrel Costs
Few shooters factor in the full, true cost of barrel life. Depending on caliber, that can dramatically increase the cost per round. For example, consider a long-range rifle in 6.5/284 caliber. This cartridge performs amazingly well, but at a cost. Ballpark estimated barrel life [in a top-quality barrel] is 1100 rounds. Some wear out faster, some last longer, but this gives a rough idea of what to expect.

Accurate barrels are a joy to use, but they are an expendable resource!
Shooting Cost by Cartridge Caliber type USAMU

A top-quality barrel plus installation was estimated at about $520.00. At 1100 rounds, barrel life adds $0.47 per round to our total cost. Thus, what had started out as an [components-only estimate, with brass cost] of $0.76/round now totals $1.24 per shot!

Cost Considerations When Choosing a Catridge Type
Some shooters might ask themselves if they could meet their present needs with a more economical caliber. If so, that equates to more practice and matches per available dollar, and more potential skill increase on the available budget.

Each shooter knows his skill level, practice needs, and shooting discipline’s requirements. Some might shoot NRA Service Rifle or Match Rifle using a 5.56mm with a long barrel life. Others might be Match Rifle shooters faced with choosing between, say, a 6mm BR vs. 6XC. A realistic assessment of ones needs, performance-wise, may help guide the shooter toward a caliber that’s most optimized to their needs at the moment.

Admittedly, the factors affecting cost for any individuals circumstances can vary significantly. However, hopefully this will provide one useful method of evaluating one’s training and competition choices, based on their skill, goals and needs.
