Can sustained rapid-fire shooting with no cool-down period wear out a quality barrel more quickly? The answer is “Yes” according to Forum member LCazador, who did an interesting comparison test with two .243 Winchester barrels. He started off with two, identical, match-grade HV taper stainless barrels. Both were NEW at the start of testing, and LCazador shot the same load through each: 95gr match bullets with 38 grains of Hodgdon Varget. After giving both barrels the same, gentle 20-round break-in, 300 rounds were then fired through each barrel — in very different ways. Barrel condition and wear were monitored with a borescope.
Barrel One — Slow Fire, Cool Down Periods, Cleaning Every 50 Rounds
At the end of the 300-round test, Barrel One looked brand new. There was none of the severe fire cracking found in Barrel Two. This barrel was shot no more than 10 times without a cool down and firing was done at a much slower pace. Cleaning for this barrel was done every 50 shots.
Barrel Two — Fast Firing, No Waiting, Cleaning Every 100 Rounds
The second barrel, which received hard use and minimal cleaning, was severely damaged with severe fire cracking at the leade and throat. As a result, the barrel had to be re-chambered. This barrel was shot 100 rounds at time without cleaning and was shot up to 20 times in succession without a cool down.
LESSON LEARNED — Heat Kills Barrel Life
Don’t let your barrel get too hot, and keep it clean. One afternoon can ruin a barrel!
Monitoring Barrel Wear with Borescope
Some folks worry too much about what their borescopes reveal — many barrels do not have to be “squeaky clean” to perform well. In fact some barrels run better after ten or more fouling shots. However, a borescope can be very helpful when your barrel starts losing accuracy for no apparent reason. Forum member FdShuster writes:
“A borescope is a positive way of backing up your suspicions when the rifle starts to throw an occasional (soon followed by more frequent) wild shot. Using the scope is also an excellent way to determine that the cause is barrel wear and not simply a need for a concentrated cleaning session to remove built up copper and more importantly, carbon fouling.
I’ve had a few barrels that gave every indication of being shot out. But I ‘scoped them out and found the cause to be nothing more than requiring a good cleaning. They then returned to their usual performance. There’s no guessing involved when you are able to get ‘up close and personal’ using the scope. The borescope also provides an excellent view of the all-important condition of the crown. My borescope is one of the most valuable investments I’ve ever made.”

What’s a “Frankengun”? Well it’s a one-of-a-kind rifle that has been pieced together from a variety of different parts and components. It might be a little bit Bolt Gun mixed with a little bit AR-15. Or it might feature some home-made components unlike anything you’ve seen before. The end result is a unique rig you won’t find anywhere else.
We’ve selected these five Frankengun rifles from an older thread in our Shooters’ Forum.
Frankengun #1 — The EXO (as in Exo-Skeleton)
Forum member jm850 calls this tube-framed wonder the EXO (as in “exo-skeleton”). He says: “This is a prototype I designed around a few core concepts that stick out to me on a traditional configuration. Eliminating stresses, lowering recoil moment, and improved barrel cooling. I’m really happy with it so far.”
The EXO is a very unique rifle. We’ve never seen anything like this since the late Shelley Davidson’s famous Tinkertoy Rifle, a brilliantly innovative 30BR that actually won matches. (Sadly Shelley has passed away). The Tinkertoy, shown below, was truely radical, but it worked ! Could this have been an inspiration for jrm850’s EXO rifle?
Frankengun #2 — Mossberg MVG in LSS Stock with BipodeXt
Forum member BallisticXLR has created something very weird to say the least. It started out as a basic, bone-stock Mossberg MVP Varmint in .223 Rem. Then the transformation began: “I replaced everything except the receiver. It now has an LSS stock, PSG-1 grip from DPMS, XLR butt stock, PT&G lug and barrel nut, Columbia River Arms 26″ barrel with Sonoran coral snake Cerakote, A2 flash hider, Timney and Jard triggers (depending on what I’m doing), and a USO B17 which is now a USO 3.8-22×44.” That long extension tube under the chassis is a BipodeXt from Accuracy Solutions.
Frankengun #3 — A Chassis Rig in 25 Creedmoor
This Frankengun belongs to Forum member Geraldgee. This “black and blue” rig features a mag-fed Kelbly Atlas action in a McCree’s Precision G10 Chassis. The barrel is a Bartlein Rem Varmint Contour, 1:7.5″-twist 4 Groove, chambered for the 25 Creedmoor. There are some interesting .25-Cal bullets coming on the market now. You can make the brass by expanding 6mm Creedmoor, or necking down 6.5 Creedmoor.
Frankengun #4 — MDT Chassis, Fore-end Whittled by Spook
Here’s a real collection of odds and ends, but Forum member Spook says it shoots well, and is a great example of “Left-over parts made useful again”. This mix-n-match Frankengun features a Remington M7 action with PT&G bolt. The barrel is a stainless Pac-Nor chambered in 6mm SLR. The barreled action is carried in an MDT Chassis with rear folding buttstock. Up front is something unusual, a Delrin fore-end that owner Spook “whittled in the mill”.
Frankengun #5 — 6.5×47 in Accuracy Int’l Stock
CLICK photo for full-screen version.
Forum member CT10Ring kicked off the Forum Frankengun thread with this rifle. It’s actually not that shocking, but you rarely see a BAT action in an Accuracy International stock. The BAT VR action is mated to an AI Mag and set up in an AI folding stock. On top is an “old school” Nightforce Benchrest scope. The barrel is a very heavy Krieger chambered for the 6.5×47 Lapua. CT10Ring say the barrel alone weighs about 9 pounds, and the gun “shoots better than [he] can”.

If you are looking for a modern, extremely powerful semi-auto pistol, you may want to consider the impressive S&W Performance Center M&P 10mm M2.0 pistol. This boasts a long 5.6″ barrel for extra velocity. The barrel is also ported for reduced muzzle flip and less perceived recoil. The gun would be a very powerful defensive pistol and S&W says it can also serve for hunting.
Smith & Wesson states: “The new Performance Center 10mm was conceived with both the hunter and target shooter in mind. The goal was to build upon the M2.0 10mm series, with the intention of having reduced felt recoil and quicker follow-up shots. Popular features previously seen on other 5.6-inch PC pistols are present in this design and, when paired with the flat-shooting 10mm Auto cartridge, provide the end user a total package for hunting, self-defense, or at the range.”
Building off the success of the M&P 10mm M2.0, Smith & Wesson incorporated new features designed to increase the new Performance Center 10mm pistol’s performance. Chambered in 10mm Auto, this full-size polymer handgun boasts a ported 5.6-inch barrel to reduce muzzle rise, optic-height tritium night sights for a clear sight picture in low-light conditions, and a Performance Center-tuned flat M2.0 trigger with a crisp break and audible reset.
The Performance Center 10mm slide is cut for optics and ships with Smith & Wesson’s C.O.R.E. plate system, two 15-round magazines, and four interchangeable palmswell grip inserts. This 10mm pistol is made in the U.S.A. and has an MSRP of $749.00.

The Making of MatchKings — How Sierra Produces SMKs
All Sierra bullets begin life as a strip of gilding metal, an alloy consisting of 95% copper and 5% zinc. To meet Sierra’s strict quality requirements, the gilding metal requires three times more dimensional and quality control standards than is considered standard in the copper manufacturing industry.
A blanking press stamps out a uniform disc and forms the cup that will be drawn into the MatchKing jacket. The cup is then polished and sent to a draw press to be drawn into a jacket that is longer than needed for the future MatchKing, thus allowing for the trim process. Press operators constantly check concentricity to ensures jacket quality. The jackets then go to a trimmer where they are visually inspected again.
After being polished a second time, the jacket travels to the bullet press. In the meantime, 80-pound lead billets are being extruded into lead wire for the cores where great care is taken so that the core wire is not stretched. The core wire is lightly oiled before continuing to the bullet press to be swaged.
The lead core wire and trimmed jacket meet at the bullet press where the first stage forms a boattail on the jacket. The lead core is then formed on top of the bullet press and fed down into the jacket. In one stroke of the press, the MatchKing is formed.
Quality control technicians pull samples from each lot of MatchKings to make sure they meet Sierra’s stringent standards. Samples are then sent to Sierra’s 300-meter underground test range (shown below) to be shot for accuracy on mechanical mounts referred to as “unrestricted return to battery rests” that Sierra designed and built in-house.
After inspection, the bullets are placed in the familiar green box along with reloading labels. They are then shrink-wrapped and shipped all over the world.

Spring Groundhog Hunting — Fun and Challenging
Springtime is the right time for groundhog hunting in the Northeast USA. Groundhog hunting is both fun and challenging. In today’s Saturday Showcase, we feature three videos showing successful groundhog hunts. Then there is a video about checking your equipment and verifying your varmint rifle zero.
We’ve even included a good video offering cooking tips for groundhog/woodchuck.* Yes groundhog meat can be quite savory — used in stews, sandwiches, or tacos. Last but not least we’ve included a section on groundhog shooting matches. These are fun matches with paper and/or steel groundhog targets.
Groundhog Hunt Report — Successful Stalk and Shoot
Here’s a great Realtree.com video showing successful groundhog hunts. This covers the process of spotting and tracking groundhogs on farmlands. Woodchucks are sensitive creatures that get easily spooked. This video shows that groundhog hunters need patience and skill, plus an accurate rifle.
Groundhog Hunting on the Family Farm with .17 HMR
In this video, the host employs his CZ 457 rifle chambered in .17 HMR to hunt groundhogs on his farm. The video provides a hunter’s POV with excellent Scope-Cam footage. This young shooter has 280 videos on his popular Blocketh Outdoors Channel including videos showing how to stalk groundhogs successfully. These critters go to ground quickly if they see or hear the hunter. NOTE: The lead photo for this Saturday Showcase comes from another Blocketh Outdoors groundhog video.
Groundhog Killshot Compilation Video
Here’s a classic “killshot” video showing multiple hits on groundhogs. If you want to see how a well-aimed varmint bullet can flip, spin, and elevate a groundhog, this video will keep you entertained. While we like explosive hits on prairie dogs, it may be better to use a solid, non-expanding bullet if you plan to harvest the groundhog (aka woodchuck) meat.
Groundhog Hunting — Importance of Confirming Your Zero
This AR15 Hunter channel video covers getting ready for spring groundhog season. This is a helpful video that shows how to confirm your zero on your varmint rifle. If you have an AR-platform Modern Sporting Rifle, this video is worth watching.
If you don’t have groundhogs in your part of the USA, don’t fret. You can still have fun hunting smaller varmints such as ground squirrels and Prairie Dogs. Here’s a good video covering P-dog hunts with a suppressed .223 Rem AR. The video covers recommended equipment including bipod, tripod, and optics.
Groundhog Matches — Fun Shooting at Paper and Steel ‘Hogs
Along with actual groundhog hunting, many shooters like to shoot paper and/or steel groundhogs in club groundhog competitions. These are fun matches that you can shoot with a variety of rifles. Our first choice would be a 22 BR for ranges out to 450 yards or a 6 BRA if targets are farther out. One popular match in the Northeast is the St. Thomas Ground hog shoot in Pennsylvania (see below).
At clubs across the country, varmint fun shoots (also known as “groundhog matches”) are becoming more popular every year. In these matches, usually shot from the bench, you engage paper targets, clay pigeons, steel “critter” silhouettes, or some combination of paper and reactive targets. Shooters like these matches because you can shoot a wide variety of rifles, you don’t have to spend a fortune to be competitive, and there is fun for the whole family. Rules are inclusive — you won’t be turned away because your rifle is two ounces overweight. A large percentage of the match fees usually go back to shooters in the form of cash prizes. And the level of camaraderie is high.
St. Thomas Groundhog Shoot, Report by Jonathan Trivette
Nestled at the base of a mountain in south-central Pennsylvania is the St. Thomas Sportsmen’s Association. On a cool Saturday morning you’ll find some of the area’s best shooters at the monthly Groundhog Match. The match attracts shooters from Virginia, Maryland, West Virginia, and of course Pennsylvania.
It may not be the longest-yardage match in the area, but it can be the one of the toughest. The range is sloped up the mountain a little so the winds can be very tricky. Often times the three wind flags at 200, 300, and 400 yards will all be blowing in different directions.
* “Groundhog” and “Woodchuck” are simply two different names for the same animal. Both terms have been used in the English language since the 1600s. In many places, the terms are used interchangeably, but “groundhog” is now increasingly more common in the USA.

Most of us own a .223 Rem rifle. Now, thanks to our friends at Rifleshooter.com we can assess exactly how velocity changes with barrel length for this popular cartridge.
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. The Rifleshooter.com team that conducts these tests has a full-service gun shop, 782 Custom Gunworks — visit 782guns.com.
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.

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.”
See More Barrel Cut-Down Tests on Rifleshooter.com
Rifleshooter.com has performed barrel cut-down tests for many other calibers/chamberings including 6mm Creedmoor, .308 Winchester, and .338 Lapua Magnum. See these test results at Rifleshooter.com.
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. And, of course, different cartridge types and powder/bullet combinations will yield different results.

When it comes to shooting targets, “Variety is the spice of life”. Shooting the same old target over and over again can get boring. We like to shoot a variety of targets. And we have to admit, the arrival of a new set of colorful targets in the mailbox has been known to motivate us to grab our guns and head to the range.
Midsouth Shooters has a large selection of colorful Champion and Birchwood Casey printed targets, both the splatter variety and conventional types. Here are some of our favorite fun-shooting targets available from Midsouth Shooters. These are in-stock currently or can be back-ordered. For sighting-in a hunting rifle, we really like the Big Burst 12″ adhesive orange-on-black grid target. This offers the aiming benefits of a precision grid along with bright shot splatter effects so you can instantly see shot point of impact.

Do you know what the inside of a rifle chamber (and throat zone) really looks like? Do you understand the concept of headspace and why it’s important? If not, you should read the Brownells GunTech article Gauging Success — Minimum Headspace and Maximum COL. This article explains the basics of headspace and shows how to measure headspace (and length to lands) in your barrels with precision. The article also explains how to adjust your full-length sizing dies to “bump the shoulder” as needed.
Why is headspace important? The article explains: “Controlling headspace and setting proper C.O.L. also represent improved safety and reduced cost of handloading. Excessive headspace can cause case head separation and gases in excess of 60,000 PSI escaping from a rifle’s chamber. Too little headspace can result in a chamber forced bullet crimp and a bullet that becomes an obstruction more than a properly secured projectile. Excessive C.O.L. can result in a rifling-bound bullet, a condition that could result in spikes of excessive pressure.”
[Editor’s NOTE: It is common for competitive benchrest shooters to seat bullets into the rifling. This can be done safely if you reduce your loads accordingly. With some bullets we often see best accuracy .010″ (or more) into the lands. However, this can generate more pressure than the same bullet seated .010″ away from initial lands contact. As with all reloading, start low and work up gradually.]
Headspace is a measurement from the bolt-face to a point in the chamber. This point of measurement will vary based on the type of cartridge. Improper headspace, either excessive or (conversely) under SAAMI specifications, can cause a variety of problems, many serious.
How is headspace specified? Most cartridges used within the United States are defined within ANSI/SAAMI Z299.3-4. Brownells explains: “In the case of the .243 Winchester, as an example, there are pressure specifications, cartridge drawings and, as pictured above, chamber drawings. Armed with a chamber drawing, each manufacturer producing a firearm for the .243 Winchester knows the proper standard dimension to cut chambers and set headspace. Notice there are two headspace reference dimensions for the chamber. The upper is a place in the chamber where the shoulder is .400″ in diameter; the “datum” or “basic” line. The lower is the 1.630″~1.640″ minimum – maximum dimension from the breech face (bolt face) to that point in the chamber that measures .400″.”
The actual headspace of any firearm is the distance from the breech face to the point in the chamber that is intended to prevent forward motion of a cartridge.
Finding Cartridge Length to Lands with OAL Gauge
Using a comparator on a set of calipers, you can quickly determine cartridge base-to-ogive length. This is the measurement from the base of the case to the forward-most full diameter section of the bullet, which is for convenience called the ogive. (Technically, the “ogive” is the full curve from bullet tip back to full-diameter ring). Shown here, that ogive is 0.243″ diameter.
The next step is using a modified (threaded) case with a Hornady OAL tool to determine Length-to-Lands (LTL) in your rifle’s chamber. During this measurement process, the modified case, with a bullet in its neck, is inserted in the chamber. Go slow, take your time. Here are 5 tips that will help you get repeatable and reliable LTL measurements:
1. Start with a clean chamber and clean barrel throat.
2. Make sure the modified case is fully screwed down and seated on the OAL Gauge. It can sometimes unscrew a bit during repeated measurements.
3. Insert the modified case slowly and gently, but ensure the shoulder of the modified case is fully seated on the end of the chamber.
4. Push the gray plastic rod GENTLY. It is common for the bullet to be tilted a bit. You want to allow the bullet to self-center in the throat BEFORE you apply much pressure. Then tap a couple times and push until you feel resistance. Do NOT push too hard — that will jam the bullet in the lands.
5. Repeat the measurement at least 3 more times. If you follow our instructions, you should, typically, get a repeatable measurement, within 0.0015″ or so, 3 out of 4 times.

Virginia Governor Glenn Youngkin has vetoed two dozen anti-gun bills passed by the Democrat-controlled Virginia General Assembly. These bills would have curtailed individual gun rights and attacked gun dealers/manufacturers throughout the Commonwealth. The NRA and NSSF (National Shooting Sports Foundation) praised Governor Youngkin for standing up to those who want to destroy gun rights in Virginia.
The NRA praised Gov. Youngkin for his actions to preserve Second Amendment rights: “[We] thank Governor Youngkin for standing strong in his support for the Second Amendment by vetoing the litany of gun control bills pushed through the General Assembly this year,” said John Commerford, Exec. Director of the NRA Institute for Legislative Action (NRA-ILA). “For the second year in a row, [Virginia] gun control activists tried to enact dozens of radical, California-style laws that would have severely restricted the Second Amendment rights of gun owners in the Commonwealth. The NRA applauds Governor Youngkin for upholding his promise to protect our Constitutional freedoms.”
The bills vetoed by Governor Youngkin came from the long wish list of radical gun control activists. This included attempts to restrict the Constitutional rights of 18- to 20-year-old adults, dramatically expand gun-free zones that would have left law-abiding Virginians defenseless and enact a mandatory waiting period to take possession of a legally-purchased firearm. In addition, the vetoed legislation would have banned a wide range of common firearms used for hunting, competition, and self-defense
Notable anti-gun bills vetoed by Gov. Youngkin this year include:
SB 848 — Remove the right of anybody under 21 years of age to purchase certain semiautomatic rifles mislabeled as “assault weapons.”
SB 891 — Mandates 5-day waiting period of five days for the purchase and transfer of firearms.
SB 1181 and HB 1607 — Bans the sale of many semiautomatic firearms and bans magazines having a capacity of more than 10 rounds.
SB 1329 — Imposes restrictions on concealed carry and storage in vehicles.
SB 1450 and HB 1608 — Creates new civil liabilities for companies engaged in the sale, manufacturing, distribution, or marketing of firearm-related products.
CLICK HERE for the official list of Virginia legislation vetoed by Gov. Youngkin so far this year. This includes the two dozen anti-Second Amendment bills he recently vetoed.
The NSSF notes that the defense of Second Amendment rights by Governor Youngkin proves that Elections DO matter. All gun owners should register and VOTE to ensure that your rights are preserved. Take time to research candidates and support those who will protect your Second Amendment rights.

A while back your Editor was in New Mexico, on a prairie dog expedition. While in the field, my companions and I used two pairs of Steiner 8x30mm Military/Marine binoculars to spot the critters. Finding the Prairie Dogs (PDs) could be challenging in the high grass. Often, a PD would reveal only its head — a small target at distances approaching 400 yards. We really needed sharp optics with high contrast to spot the dogs hiding behind tufts of grass or dry brush.
The Steiner Military/Marine binoculars performed superbly. I came away very impressed with these armored 8x30mm binoculars (now called Model 2033). The glass is bright and super-sharp. And the rubber-armored body is truly rugged. These binoculars offer both right and left diopters — important for me as my right eye requires more correction than the left eye. One great feature of the Steiners is the focusing system which keeps everything you can see in focus. This really is a big deal. You don’t have to constantly fiddle with focus — everything past about 20 yards is in sharp focus all the time.
As one Steiner owner reports: “Focusing set-up is worth the price of admission. Set it and forget. Amazing. This single feature makes these worth owning.” And the sharpness is impressive. I compared the Steiners’ image with a 6.5-20×40 Leupold EFR riflescope set at 8X. Both 8×30 Steiners were brighter than the Leupold scope, and the Steiners resolved individual blades of grass and fine details better than the Leupold. Of course, comparing a binocular optic with a riflescope is like comparing apples and oranges. The advantages of binoculars (compared to a monocular scope) are well known — the brain combines the two images (left eye and right eye) to create a more vivid, 3D effect, with greater perceived contrast.
Steiner 8×30 Military/Marine Binocs are Just $211.15
At the end of our hunt, I told my host that I planned to purchase some Steiner 8×30 Military/Marine Binoculars similar to the units we used during our New Mexico varmint hunt.
When I arrived home I was amazed to see that the Steiner 2033 8×30 Military/Marine is available for just $211.15 on Amazon.com (#ad), with free shipping. That’s a great value, considering the ruggedness and optical quality of the unit.
The Steiner 210 10×50 Military/Marine (#ad) is also offered on Amazon.com. It has more magnification and better low-light performance. However, it currently runs $420.00, nearly twice the current price of 8×30 Military/Marine on Amazon! Unless you really need the 10×50’s extra low-light capability, the 8×30 M/M is the smart choice.

When shooting groups at long range on paper it can be difficult to distinguish which bullet holes belong to a particular sequence of shots. If, for example, you shot three 5-shot groups at 600+ yards on a paper target, you would have 15 bullet holes on the target (assuming no misses). But at that distance it would be difficult to see the holes on target (even with a spotting scope). Accordingly, when you inspected the target up close, it would be hard to tell which shots belonged to which group. You might have a vague idea, but couldn’t be sure, without a target camera recording the shot sequence.
Here is a method to separate multiple shots into specific groups so you can better evaluate your load and shooting skills. The trick is pretty simple — mark your bullets with a color from a Sharpie or other felt marking pen. If you are shooting three 5-shot groups, mark five with red, five with green, and five with blue (or purple). Then, when you inspect the target, you can identify the group placements by the colors that appear on the paper.
Round Robin: Using colors you can shoot “Round-Robin” to evaluate seating depths, neck tension, or other variables without having the shot order (and barrel heating) affect group sizes unequally. For example you might have three different neck tensions, each marked with a different color on the bullets. Then shoot Red, Blue, Green in that sequence for five total shots per color.
Smart Tip to Show Colors More Vividly
If the bullet inks are not showing up on your target paper clearly, here is a simple trick that can make the colors “bleed” to be more visible. In your range kit, bring some alcohol solution along with some Q-tips. Then dab the shots on the paper target lightly with wet Q-Tips. Here is the front of a target before and after application of alcohol:
Forum Member NewbieShooter explains: “Dabbing a bit of alcohol on the bullet holes with Q-Tips makes the color pop a bit… especially on the back side.” See below:
In short order you will see the colors spread into the paper, clearly marking the shot holes by distinguishing colors. If you were shooting a dark bullseye, view the the BACK side of the target to see the colors on a light background.
