The CMP M14 Heritage Match was held Sunday, August 3, 2025 at the Viale Range at Camp Perry.
M1A rifles at M14 Heritage Match at Camp Perry
Today we feature the M1A rifle. Last week, the rugged M1A rifle, descended from the M1 Garand and M14, was the star of the show at Camp Perry. The M14 Heritage Match was held last Sunday, August 3, 2025, at the CMP 2025 National Rifle Matches.
History of the M14 Heritage Match and Springfield M1A Match
The M14 Heritage Match, previously the Springfield Armory M1A match, began with one man’s concept. Springfield Armory’s Mike Doy witnessed the waning of classic M1 Garand and M1A rifles from the competitive High Power firing lines. “I really wanted to get those M1A rifles out of safes and closets and back out onto the field. So [in 2008] I promoted the idea of running an M1A-specific match at Camp Perry. That first year we had over 600 competitors and spectators.” After running as a Springfield Armory-sponsored match (with cash prizes) for many years, the match is now the “M14 Heritage Match”.
Folks, take the time to WATCH this 3-minute video. It has great match footage of Camp Perry and interviews with M1A competitors. Well worth watching!

M1A Competition at Camp Perry National Matches
For many years, the semi-auto version of the M14 was “top dog” in iron sights Service Rifle competition. Now that discipline is dominated by .223 Rem (5.56×45) AR-type rifles, but the bigger .308-caliber rifle, now sold as the M1A, remains popular. The CMP hosts a major M1A Match every year at Camp Perry now called the “M14 Heritage Match”. Significant prizes are awarded. In past years M1A Match competitors took home over $25,000 worth of cash and merchandise when the match was sponsored by Springfield Armory.

M1A Match 2016 — Rapid Fire Sitting Stage
In the April 2018 issue of Shooting Sports USA, you’ll find a good article on the civilian version of the M14, now sold commercially as the Springfield M1A. An evolution of the battle-proven M1 Garand, the M14 was designed to shoot the 7.62×51 (.308 Win) round instead of the larger .30-06 Springfield cartridge used in WWI, WWII and Korea. While the vast majority of today’s M1As are chambered for .308 Win/7.62×51, Springfield Armory also produces a 6.5 Creedmoor version.
Dick Jones reports that accurized M14/M1As could post remarkable scores: “The accuracy potential of the M14/M1A is unquestionable. During their reign as service rifles, they produced multiple perfect 200 scores at 600 and 1000 yards in the hands of top shooters. This is a difficult feat with a modern, scoped, magnum-caliber rifle and remarkable with an iron-sighted battle rifle. Good competition rifles can group 10 shots under one MOA, and the meticulously-massaged rifles used by the top shooters during my career would consistently put up 10 shots under an inch at 200 yards off a test cradle.”
In this video, YouTube Reviewer Hickok 45 compares the M1 Garand and the M14/M1A:
“Descended from the M1 Garand, the M14 utilized multiple improvements that made it a far superior firearm for combat and a much better rifle for competition.” — Dick Jones, Shooting Sports USA.
M1A Match Equipment Rules and Course of Fire
Renewed interest in the M1A led to the first dedicated Camp Perry M1A match in 2008. That first-ever match drew over 500 shooters. Match equipment rules allow pretty much all types/grades of M1As. The one-day course of fire consists of 50 shots at 300 yards on the NRA MR-65F target, as follows: 5 sighters; 20 shots slow-fire prone; 10 shots rapid-fire prone; 10 shots rapid-fire, kneeling or sitting; and 10 shots slow-fire standing. Here are photos from the 2014 MIA match, courtesy NRA General Operations.
See how the modern M1A is built in this Springfield Armory Video:
As racing improves automobiles, competition improves firearms, and the current crop of Springfield M1As, from the Basic to the top-of-the-line Super Match and Loaded models, reflects the years of development. The M14 and its variants are … still considered by many to be the best battle rifle in the history of the U.S. Military. — Dick Jones, Shooting Sports USA
What is Parallax?
Parallax is the apparent movement of the scope’s reticle (cross-hairs) in relation to the target as the shooter moves his eye across the exit pupil of the riflescope. This is caused by the target and the reticle being located in different focal planes.
Here’s a good explanation of scope parallax. This video has been watched over 790,000 times.
Why is it Important?
The greater the distance to the target and magnification of the optic, the greater the parallax error becomes. Especially at longer distances, significant sighting error can result if parallax is not removed.
How to Remove Parallax
This Nightforce Tech Tip video quickly shows how to remove parallax on your riflescope.
While keeping the rifle still and looking through the riflescope, a slight nod of the head up and down will quickly determine if parallax is present. To remove parallax, start with the adjustment mechanism on infinity and rotate until the reticle remains stationary in relation to the target regardless of head movement. If parallax has been eliminated, the reticle will remain stationary in relation to the target regardless of eye placement behind the optic.
So you’re thinking of buying a suppressor (aka “moderator”, “silencer”). You can’t just get one off the shelf at Walmart. Acquiring a suppressor requires filling out paperwork and paying a Federal $200 Tax Stamp. Plus there is typically a pretty long wait. However, the good news is that suppressor ownership is now legal in 42 of the 50 American states — that’s 84%! For most American adults, getting a suppressor is legal, provided the buyer passes the required background checks (explained below). The 42 “suppressor-friendly” states are shown as RED in the illustration below.
States Where Suppressor Ownership is Allowed
These 42 states allow private ownership of suppressors: AL, AK, AZ, AR, CO, CT, FL, GA, ID, IN, IA, KS, KY, LA, ME, MD, MI, MN, MS, MO, MT, NE, NV, NH, NM, NC, ND, OH, OK, OR, PA, SC, SD, TN, TX, UT, VT, VA, WA, WV, WI, WY. Note: Even if you live in one of the states listed, you should still verify that owning a suppressor is legal in your area. Some states may have municipal- or county-based restrictions.
“Suppressor ownership [has] boomed in the 21st century. Thanks in part to companies like Silencer Central that streamline the purchasing process, the number of registered suppressors has grown from 285,000 in 2010 to over 2.6 million in 2020.” — GunsAmerica Digest
States Which Prohibit Suppressor Ownership
The eight states which prohibit suppressor ownership are: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Rhode Island. These states are shown in GRAY in the map.
Good News — Suppressor Tax Will Be Eliminated Next Year
The suppressor transfer tax has not been eliminated yet, but it will be reduced to $0 (zero) starting January 1, 2026. This law change was effectuated by recent Federal legislation through Congress and signed by President Trump. The “One Big Beautiful Bill”, passed by Congress and signed into law by President Trump on July 4, 2025, includes a provision reducing the NFA tax stamp on suppressors and short-barreled firearms to $0. The Silenco Video below from 8/4/2025 explains the new law changes.
Current Status: As of today, August 10, 2025, the $200 tax stamp is still required for the purchase of suppressors and other NFA items.
Effective Date: This change to a $0 tax stamp will take effect on January 1, 2026.
Interim Period (August 2025 – December 2025): Some retailers, like Silencer Central, are offering promotions to cover the $200 tax stamp fee on select suppressors purchased before the $0 tax stamp becomes effective, according to Silencer Central.
NFA Regulations Still Apply: Even after the tax stamp is eliminated in 2026, suppressors will still be regulated under the National Firearms Act (NFA). This means you’ll still need to go through the ATF process, including fingerprinting and background checks, to acquire a suppressor.
Qualifications to Obtain a Suppressor
To legally obtain a suppressor, you must fill out Federal Forms and pay a $200 fee to the ATF. You must also pass BATFE background checks and otherwise comply with Federal and state laws. States can regulate suppressor ownership or use, so be sure to check the laws in your area. On the federal level, the process to acquire a suppressor is regulated under the National Firearms Act of 1934. According to the American Suppressor Association, to own a suppressor in the United States you must:
1. Be at least 21 years of age to purchase a suppressor from a dealer.
2. Be at least 18 years of age to purchase a suppressor from an individual on a Form 4 to Form 4 transfer (contingent on state laws).
3. Be at least 18 years of age to possess a suppressor as a beneficiary of a trust or as a member of a corporation (contingent on state laws).
4. Be a resident of the United States.
5. Be legally eligible to purchase a firearm.*
6. Pass a BATFE background check with a typical process time of 8 to 10 months.
7. Pay a one time $200 Transfer Tax. NOTE: This tax will be eliminated as of 1/1/2026.
*That fifth requirement, “be legally eligible to purchase a firearm”, involves a list of factors. The prohibitions are set forth in the “prohibited person” list found on ATF Form 4473.
Varminting for Fun — With Rimfires and Centerfires
One of the most fun things you can do with a rifle is to shoot varmints such as ground squirrels, prairie dogs, rockchucks, and groundhogs. There’s great satisfaction making a perfect hit on a critter that sends the beastie spinning in the air. Varminting also affords a great excuse to acquire more rifles, because it really does make sense to own and use multiple varmint rifles in various calibers.
Having multiple rifles on a varmint safari lets you preserve barrel life, and shoot lesser-recoiling calibers at the shorter distances. For example, with California ground squirrels, we like a .17 HMR inside 125 yards, then switch to a 20 Practical (20-223 Rem). For prairie dogs, you may want that 20 Practical, plus a nice .22 BR for 250-400 yards, and a .243 Ackley (or 6XC or 6mm CM) for long shots.
Seven Varmint Rifles — Rimfire and Centerfire
With 980,000 subscribers, the Backfire YouTube Channel is highly popular. The capable hosts provide honest, candid reviews. This video covers seven different varmint rigs. First off is the Air Arms TX 200 (00:25). Then the excellent .22 LR CZ 457 is featured (01:33), followed by a .223 Rem AR15-platform rifle (02:30). Next up is the .22 LR Christensen Arms Ranger 22 (03:40), which proved to be “crazy accurate”. Then the video showcases a Bergara Premier in 22-250 (04:20), an “excellent coyote gun that you could use on varmints as well”. Last up is the Ruger American Predator (05:20) in .17 HMR.
6XC Rifle Featured in Gunwerks Rockchuck Adventures
This Gunwerks video showcases varmint hunting in the Western USA. In this video Aaron Davidson and the Gunwerks crew try out some new rifles on some rockchucks. Most of the the rifles were suppressed but the host said the rockchucks took cover after the first shot, so this required good coordination among shooters and spotters. A 6XC varminter is featured at 2:44 and there’s some nice drone footage starting at 2:00.
6mmBR for Longer Range Varmint Adventures
The video creator reports “I spent a great deal of time deciding what 6mm cartridge I would pick for my next varmint build. I was sure of certain things. First, it had to fit an action that I owned. Most importantly, it had to be highly accurate, with light recoil. Quality, highly frangible bullets had to be available in the 50 to 70 grain weight range (for smaller to larger varmint hunting). For flat shooting ballistics, I wanted velocity above 3300 fps. I decided that the 6mmBR, with a slow twist barrel, was what I was looking for.” Components for this rifles are: Borden Alpine Action, Krieger Barrel, Grayboe Ridgeback Stock, Bix’N Andy Trigger, Thunderbeast Ultra Suppressor.
.22-250 Nails Ground Squirrels and Rock Hyraxes in South Africa
Here’s an interesting video from South Africa. The video maker starts with shots on ground squirrels. His .22-250 blasts them into little pieces. They he switches to more distant targets, a furry ground-hog size animal called the Rock Hyrax, Cape Hyrax, or Dassie. Mature Rock Hyraxes weigh 4-5 kilograms and have short ears and tail. These Rock Hyraxes are found at higher elevations in habitats with rock crevices, allowing them to escape from predators (but not skilled varmint hunters).
20 Practical — Great Choice for AR-Platform Rifle
If you want to use an AR-platform rifle in the varmint fields, consider getting a 20-caliber barrel chambered for the efficient, low-recoil 20 Practical cartridge. The 20 Practical is simply a .223 Remington necked down to 20 caliber. The parent .223 Rem cartridge of course works great in an AR, but the 20 Practical offers some notable advantages for high-volume varmint shooters. The 20 Practical cartridge is simply the .223 Rem necked down to 20 caliber — you can use standard .223 brass and load with standard.223 Rem dies. Just swap in a smaller expander and use smaller neck bushings.
The 20 Practical delivers very high velocity with very low recoil while still providing outstanding accuracy. The 20 Practical is great option for folks who favor “fast and light” — smaller, lower-mass bullets traveling at very high velocities. This little cartridge can launch 40-grainers at over 3900 fps.
.17 WSM — The Most Powerful .17 Cal Rimfire
We think that every varmint hunter should own a nice .17 Cal rimfire rig. Out to 200 yards or so the .17 WSM or .17 HMR is very effective on small varmints. It’s nice to be able to shoot affordable ammo out of the box and not have to scrounge for hart-to-find powder and primers. This video features a superb .17 Cal varmint rig, the Primal Rights TS Custom chambered for the impressive .17 WSM cartridge.
Prairie Dog Hunting with .17 HMR Savage A17 Rifle
On varmint excursions, we like to have a .17 rimfire for the closer shots, inside 150 yards. This video shows a successful Prairie Dog hunt with a .17 HMR. Watch and you’ll see hits out to 160 yards (00:50), proving the effective range of the .17 HMR cartridge. The host is shooting a Savage A17 semi-auto 17 HMR rifle in a Boyds laminated stock.
Varminters now enjoy three .17-caliber rimfire options. The .17 Mach 2, .17 HMR, and .17 WSM are all good choices, with the 17 Mach 2 (17 HM2) being the cheapest and the .17 WSM the most powerful. With a 3000 fps MV, the .17 WSM has some really impressive ballistics, — with a much flatter trajectory than both the .17 HMR and .22 WMR:
For many Americans, real incomes have stayed flat in recent years, while inflation increased the cost of living very significantly during the Biden presidency. The 2025 quarterly inflation rates are lower, yes, but prices are still rising. Accordingly, it’s important to save money whenever possible. Prices are going up, but wages aren’t following (for most of us). Here are six ways shooters can save money on gear purchases and other shooting-related expenses.
1. Watch for Our Deals of the Week. Every Monday, in our Daily Bulletin, AccurateShooter.com offers some of the best deals to be found. We search the web to find great deals on ammo, reloading components, optics, tools, firearms, gun safes, electronics and more. It’s not unusual to find savings of 20-35% through our Deals of the Week. And many of our vendors are now offering special deals just for AccurateShooter.com readers.
2. Check Out the Forum Classifieds. There are great deals to be found every day in the AccurateShooter Shooters’ Forum. The latest deals are displayed in the right column of every Forum page. To see all the listings, browse through the Forum MarketPlace section which has four main categories:
Guns, Actions, Stocks, & Barrels
Tools, Dies, Rests, Reloading Components & Misc
Scopes, Optics, Sights, Rings, Bases Etc.
Commercial Sales by Paid Sponsors
3. Share a Ride to Matches. Fuel prices are on the rise — Regular-grade gasoline is over $4.90 per gallon in California now and around $3.20+ per gallon nationwide. With many shooters living 30-100 miles from the nearest range, fuel remains a big part of a shooter’s hobby budget. We’d say 90% of shooters drive solo to matches, often in large, gas-guzzling trucks. If you drive 200 miles round-trip to attend a match in a 20-mpg vehicle, you’ll burn over $32.00 worth of gasoline on your trip. That adds up. By simply sharing the ride with one fellow shooter you cut your fuel expenditures in half. And, if you alternate vehicles with a buddy from one match to the next, you save on vehicle wear and tear. At $0.70/mile (overall operating costs) consider the savings.
4. Use Discount Codes to Save. It’s always smart to check for discount codes before you buy. In the Daily Bulletin, we feature “Deals of the Week” every Monday morning, and we provide discount Coupon Codes when available. These can reduce the price substantially or lower shipping costs. Search codes for Brownells, Creedmoor Sports, EuroOptic, Graf’s, Midsouth, Powder Valley, Sportsman’s Warehouse, KYGUNCO, MidwayUSA, and Precision Reloading. Check your email also — some discount codes are only announced in email newsletters. If you can’t find a Coupon Code for your preferred vendor, visit Gun.deals and/or RetailMeNot.com. Both those sites list current coupon codes, and RetailMeNot.com covers thousands of vendors.
5. Shop for “Demo” Optics. Modern high-quality optics can easily cost $2000.00 or more, often exceeding the value of the rifle on which they are mounted. However, you can often save 20-30% by purchasing demo optics. These are normally display units used at trade shows. They may have slight ringmarks, but otherwise they are “as new”, having never been carried in the field or used on a rifle that has fired live ammo. When purchasing demo scopes, you should always ask about the warranty before making the sale. However, most demo scopes from name-brand manufacturers come with full factory warranties. EuroOptic.com and Bruno Shooters Supply are two respected vendors that offer a good selection of demo optics.
6. Train with Rimfire Rifles. Good match-grade centerfire, hand-loaded ammo, counting premium bullets, powder, primers, and brass (figuring 10X loads), can now exceed $1.50 per round. And if your $600 (as chambered and fitted) competition barrel is toast after 1500 rounds, add $0.40 for barrel deprecation per shot. So you’re approaching two bucks a round total! By contrast, you can get quite good .22 LR target ammo for $0.16 per round. Good rimfire barrels last a long, long time, so you don’t have to be concerned about wearing out your barrel quickly. A quality rimfire barrel can retain its accuracy for 7,000 rounds or more. If you run the ballistics, a .22 LR round at 100 yards can emulate the wind drift experienced by a centerfire cartridge at long range. This allows for effective cross-training with much less expensive ammo.
Tired of spending $15-$25 for a can of spray lube that doesn’t last that long? For about the same price as a single 10 oz. can you can make your own effective spray lube that should last for multiple seasons and lube thousands of cases quickly and easily.
In the YouTube video embedded below, our friend Gavin Gear of UltimateReloader.com shows how to make your own case lube using simple, inexpensive ingredients. As recommended by the 6.5 Guys, this Liquid Lanolin + Isopropyl Alchohol mix works well and is very cost-effective. You can make a pint of this home-brew Lanolin case lube that will lube thousands of cases — many more than a typical commercial aerosol spray can (that’s mostly compressed air).
Gavin describes the exact mixing process on his Ultimate Reloader website. Gavin says this lube mix is a good complement to the Hornady One-Shot (pistol) and Dillon DCL (rifle) lubes he has used for pistol and rifle reloading sessions. CLICK HERE to read more.

President Trump Issues Executive Order Ending Banking Discrimination
NSSF, the Firearm Industry Trade Association, applauds President Donald Trump’s recent signing of an Executive Order Guaranteeing Free and Fair Banking for All Americans. This Executive Order enforces a firearm industry priority to end banking discrimination against individuals and entities based on political beliefs. For years, firearm industry companies and gun sellers have been denied banking and financial services by banks espousing anti-Second Amendment policies.
“President Trump is yet again delivering on his promise to protect Americans’ rights. This time by ensuring that banks cannot discriminate against firearm-related businesses…” said Lawrence G. Keane, NSSF Sr. V.P. and General Counsel. “American businesses, and firearm businesses in particular, must have fair access to essential banking services that are based on an objective criteria and creditworthiness. Politics should not enter into a bank’s lending decision.”
President Trump’s Executive Order cited attempts by the previous administration to compel corporate banks to surveil Americans exercising their Second Amendment rights. The President also noted the illegal “Operation Choke Point”, executed by the Obama administration, former U.S. Attorney General Eric Holder and the Department of Justice (DOJ), along with the Federal Deposit Insurance Corporation (FDIC), to deny essential banking services to firearm-related businesses based on an ill-defined “reputational risk” criteria.
Banking regulators during the Biden administration also illegally pressured banks to refuse banking services based on politics. Before Biden took office, the first Trump administration pushed a Fair Access to Banking rule by the Office of the Comptroller of the Currency (OCC). However, in 2021, the Biden administration halted that Fair Access Rule before it could become effective.
In our Shooters’ Forum, there was an discussion about a range that was threatened with closure because rifle over-shoots were hitting a farm building over two miles from the firing line. One reader was skeptical of this, asking “how’s that possible — were these guys aiming at the stars?” Actually, you may be surprised. It doesn’t take much up-angle on a rifle to have a bullet land miles down-range. That’s why it’s so important that hunters and target shooters always orient their barrels in a safe direction (and angle). Shooters may not realize how much a small tilt of the barrel (above horizontal) can alter a bullet’s trajectory.
How many degrees of muzzle elevation do you think it would take to hit a barn at 3000 yards? Ten Degrees? Twenty Degrees? Actually the answer is much less — for a typical hunting cartridge, five to seven degrees of up-angle on the rifle is enough to create a trajectory that will have your bullet impacting at 3000 yards — that’s 1.7 miles away!
Five degrees isn’t much at all. Look at the diagram above. The angle actually displayed for the up-tilted rifle is a true 5.07 degrees (above horizontal). Using JBM Ballistics, we calculated 5.07° as the angle that would produce a 3000-yard impact with a 185gr .30-caliber bullet launched at 2850 fps MV. That would be a moderate “book load” for a .300 Win Mag deer rifle.
Here’s how we derived the angle value. Using Litz-derived BCs for a 185gr Berger Hunting VLD launched at 2850 fps, the drop at 3000 yards is 304.1 MOA (Minutes of Angle), assuming a 100-yard zero. This was calculated using a G7 BC with the JBM Ballistics Program. There are 60 MOA for each 1 degree of Angle. Thus, 304.1 MOA equals 5.068 degrees. So, that means that if you tilt up your muzzle just slightly over five degrees, your 185gr bullet (2850 fps MV) will impact 3000 yards down-range.
Figuring Trajectories with Different Bullets and MVs
If the bullet travels slower, or if you shoot a bullet with a lower BC, the angle elevation required for a 3000-yard impact goes up, but the principle is the same. Let’s say you have a 168gr HPBT MatchKing launched at 2750 fps MV from a .308 Winchester. (That’s a typical tactical load.) With a 100-yard zero, the total drop is 440.1 MOA, or 7.335 degrees. That’s more up-tilt than our example above, but seven degrees is still not that much, when you consider how a rifle might be handled during a negligent discharge.
Think about a hunter getting into position for a prone shot. If careless, he could easily touch off the trigger with a muzzle up-angle of 10 degrees or more. Even when shooting from the bench, there is the possibility of discharging a rifle before the gun is leveled, sending the shot over the berm and, potentially, thousands of yards down-range.
Hopefully this article has shown folks that a very small amount of barrel elevation can make a huge difference in your bullet’s trajectory, and where it eventually lands. Nobody wants to put holes in a distant neighbor’s house, or worse yet, have the shot cause injury.
Let’s go back to our original example of a 185gr bullet with a MV of 2850 fps. According to JBM, this projectile will still be traveling 687 fps at 3000 yards, with 193.7 ft/lbs of retained energy at that distance. That’s more than enough energy to be deadly.
This illustration shows headspace measurement for the popular .308 Winchester cartridge, which headspaces on the shoulder. Image copyright 2015 Ultimate Reloader.
In this Brownells Tech Tip Video, Brownells gun tech Steve Ostrem explains what headspace is and why it’s one of the most critical measurements for nearly all firearms. Even if you’re an experienced rifle shooter, it’s worth watching this video to refresh your understanding of headspace measurements, and the correct use of “GO” and “NO-GO” gauges.
Headspace Definition
In firearms, headspace is the distance measured from the part of the chamber that stops forward motion of the cartridge (the datum reference) to the face of the bolt. Different cartridges have their datum lines in different positions in relation to the cartridge. For example, 5.56x45mm NATO ammunition headspaces off the shoulder of the cartridge, whereas .303 British headspaces off the forward rim of the cartridge. If the headspace is too short, ammunition that is in specification may not chamber correctly. If headspace is too large, the ammunition may not fit as intended or designed and the cartridge case may rupture, possibly damaging the firearm and injuring the shooter. (Source: Wikipedia)
Problems Caused by Too Much Headspace
Excessive headspace issues can include: light primer strikes, failure to fire, bulged/blown cases, case separations, split shoulders, or unseated primers after firing. Case ruptures caused by excessive headspace can lead to catastrophic failures causing serious injury. That is why headspace is such an important measurement.
Problems Cause by Too Little Headspace
Insufficent (or excessively tight) headspace can prevent the firearm from going into battery, resulting in failure to fire or deformation of the cartridge case. Various feeding and functioning problems can be caused by cases with too little headspace, even if a round can be chambered (with effort).
Headspace Gauges
Headspace is measured with a set of two headspace gauges: a “Go” gauge, and a “No-Go” gauge. Headspace gauges resemble the cartridges for the chambers they are designed to headspace, and are typically made of heat-treated tool steel. Both a “Go” and a “No-Go” gauge are required for a gunsmith to headspace a firearm properly. A third gauge, the “Field” gauge, is used (as the name implies) in the field to indicate the absolute maximum safe headspace. This gauge is used because, over time, the bolt and receiver will wear, the bolt and lugs compress, and the receiver may stretch, all causing the headspace to gradually increase from the “factory specs” measured by the “Go” and “No-Go” gauges. A bolt that closes on “No-Go” but not on “Field” is close to being unsafe to fire, and may malfunction on cartridges that are slightly out of spec. (Source: Wikipedia)
You need to understand Headspace Gauges and how to use them. There are “Go”, “No-Go”, and “Field” gauges. The “Field” is actually the longest. Brownells explains: “The GO gauge corresponds to the SAAMI minimum chamber length, while the FIELD gauge usually matches the maximum chamber depth, or slightly less. NO-GO gauges are an intermediate length between minimum and maximum, that, technically, is a voluntary dimension. A firearm that closes on a NO-GO gauge and does not close on a FIELD gauge may not give good accuracy and may have very short cartridge case life [.]”

3. Share a Ride to Matches. Fuel prices are on the rise — Regular-grade gasoline is over $4.90 per gallon in California now and around $3.20+ per gallon nationwide. With many shooters living 30-100 miles from the nearest range, fuel remains a big part of a shooter’s hobby budget. We’d say 90% of shooters drive solo to matches, often in large, gas-guzzling trucks. If you drive 200 miles round-trip to attend a match in a 20-mpg vehicle, you’ll burn over $32.00 worth of gasoline on your trip. That adds up. By simply sharing the ride with one fellow shooter you cut your fuel expenditures in half. And, if you alternate vehicles with a buddy from one match to the next, you save on vehicle wear and tear. At $0.70/mile (overall operating costs) consider the savings.
4. Use Discount Codes to Save. It’s always smart to check for discount codes before you buy. In the Daily Bulletin, we feature “Deals of the Week” every Monday morning, and we provide discount Coupon Codes when available. These can reduce the price substantially or lower shipping costs. Search codes for Brownells, Creedmoor Sports, EuroOptic, Graf’s, Midsouth, Powder Valley, Sportsman’s Warehouse, KYGUNCO, MidwayUSA, and Precision Reloading. Check your email also — some discount codes are only announced in email newsletters. If you can’t find a Coupon Code for your preferred vendor, visit 
5. Shop for “Demo” Optics. Modern high-quality optics can easily cost $2000.00 or more, often exceeding the value of the rifle on which they are mounted. However, you can often save 20-30% by purchasing demo optics. These are normally display units used at trade shows. They may have slight ringmarks, but otherwise they are “as new”, having never been carried in the field or used on a rifle that has fired live ammo. When purchasing demo scopes, you should always ask about the warranty before making the sale. However, most demo scopes from name-brand manufacturers come with full factory warranties. 
6. Train with Rimfire Rifles. Good match-grade centerfire, hand-loaded ammo, counting premium bullets, powder, primers, and brass (figuring 10X loads), can now exceed $1.50 per round. And if your $600 (as chambered and fitted) competition barrel is toast after 1500 rounds, add $0.40 for barrel deprecation per shot. So you’re approaching two bucks a round total! By contrast, you can get quite good .22 LR target ammo for $0.16 per round. Good rimfire barrels last a long, long time, so you don’t have to be concerned about wearing out your barrel quickly. A quality rimfire barrel can retain its accuracy for 7,000 rounds or more. If you run the ballistics, a .22 LR round at 100 yards can emulate the wind drift experienced by a centerfire cartridge at long range. This allows for effective cross-training with much less expensive ammo.
In our Shooters’ Forum, there was an discussion about a range that was threatened with closure because rifle over-shoots were hitting a farm building over two miles from the firing line. One reader was skeptical of this, asking “how’s that possible — were these guys aiming at the stars?” Actually, you may be surprised. It doesn’t take much up-angle on a rifle to have a bullet land miles down-range. That’s why it’s so important that hunters and target shooters always orient their barrels in a safe direction (and angle). Shooters may not realize how much a small tilt of the barrel (above horizontal) can alter a bullet’s trajectory.
