For many Americans, real incomes have stayed flat in recent years, while inflation has increased the cost of living very significantly in the past four years. 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.

3. Share a Ride to Matches. Fuel prices are on the rise — regular-grade gasoline is $5.13 per gallon in California now and around $3.54/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 $35.40 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 $0.58/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 $1500.00 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 consummating the sale. However, most demo scopes from name-brand manufacturers come with full factory warranties. EuroOptic.com and SWFA.com 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 under $0.18 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.
Creedmoor Sports has recently expanded and updated the Creedmoor Sports InfoZone. This web resource contains valuable information about reloading, rifle maintenance, marksmanship skills, and gunsmithing. In addition, the InfoZone has Competition Reports, numerous Gear Reviews, and general Shooting Sports News.
For this Saturday Showcase, you’ll find five InfoZone Videos hosted by Bill Gravatt, President of Creedmoor Sports. There are over 85 other videos on the Creedmoor Sports YouTube Channel. Bill Gravatt is an expert on reloading processes and gear. He developed many of the popular tools for Sinclair Int’l, and now he directs operations for Creedmoor Sports.
Reloading Procedures with Bill Gravatt
Here are five helpful videos Bill Gravatt created for the Creedmoor Sports InfoZone. These videos cover a variety of essential processes for handloading. In addition Bill Shows how to find the exact twist rate in your rifle barrels.
How to Determine a Barrel Twist Rate
Bill Gravatt of Creedmoor Sports demonstrates an easy method to determine your barrel’s twist rate. Knowing the twist rate is essential to selecting suitable bullets for your discipline.
How to Seat Bullets with Inline Press
Many top Benchrest and F-Class shooters favor inline presses for bullet seating. With good hand dies (such as Wilson) and a inline Arbor press (such as a 21st Century), you can get great results with super seating depth consistency and very low run-out.
How to Trim Cases with L.E. Wilson Trimmer
There are many ways to trim cartridge brass. If you need to trim hundreds of cases it may pay to have a dedicated power trimmer. However, for most rifle shooters, a good hand trimmer will do the job very well. We regularly use a Wilson trimmer to trim our cases, as demonstrated in this video.
How to Clean Cartridge Cases
It is important to regularly clean cartridge brass. There are many different means. Wiping the outside with a solvent is a good start. For more thorough cleaning inside and out tumbling or wet-tumbling will do the job. After tumbling in media, you should always check the primer pockets and flash holes before loading.
How to Clean Reloading Dies
Cleaning your reloading dies is something that many who reload often neglect. In this 60-second Tech Tip, Bill Gravatt provides some tips on cleaning your reloading dies.
BONUS Video: How to Fine Tune Seating Depth
Now that you’ve learned Reloading Basics from the Creedmoor Sports videos, here’s a great video from our friend Keith Glasscock that will help you get optimal results when seating bullets. Keith is one of America’s greatest F-Class competitors, with multiple podium finishes at F-Class National Championships. With over 213,000 views, this is the most popular video Keith has created for his Winning in the Wind YouTube Channel.

by Sierra Bullets Ballistic Technician Paul Box This cartridge was introduced by Winchester in 1935 in their model 54 rifle. A year later, it was added as a standard cartridge in the model 70. What might not be common knowledge to some reloaders is that the prototype for the Swift was developed in 1934-35 by Grosvenor Wotkyns by necking down the 250 Savage case, but in the end, Winchester chose the 6mm Lee Navy case for the foundation for this cartridge.
This cartridge was far ahead of its time and for that reason it received a lot of bad press. We’ve all read the horror stories through the years. Many of those stories were just simply repeated from previous articles even the wording was just slightly different. So how bad was the Swift? Let’s take a deeper look.
Some of the early Swifts had soft barrel steel and some of the rare ones even had barrels that were .223 in bore size. This stemmed from the fact that the .22 Hornets prior to the end of World War II were .223 in bore size and some of these barrels were chambered in the Swift. It was rumored that the Swift peaked in pressure far too quick. I’ll bet they did with a turkey extra full choke barrel.
Burn rates of powders were limited at that time as well, so the Swift was limited in its true ability due to that. It was almost like building a funny car for drag racing when only kerosene was available.
One of the longest lasting black eyes was that it shot barrels out so fast. If you get the barrel branding iron hot and fail to clean it often this can happen. Common sense will go a long ways here. Keep the barrel as cool as you can and properly clean it every fifteen rounds or less will go a long way to improving accuracy life of a Swift.
So what is the real truth about this cartridge? I’m glad you ask. I’ve been shooting the .220 Swift for over 43 years now. It is one of the best varmint cartridges I’ve ever owned. It is not hard to load for, it doesn’t suddenly peak in pressure and it isn’t the barrel burner that you’ve heard. Hodgdon powders once reported a Remington 40-X with over 3,000 rounds of full power loads averaged .344” for five, 5-shot groups. My findings have been the same. It isn’t as hard on barrels as it has been made out to be.
I’ve also read that down loading it slightly will help in barrel life. This is true, but if you buy a thoroughbred you want him to run. Barrels are threaded on the end for a reason. If you have enough fun to shoot out a Swift barrel, just rebarrel it.
The bottom line is enjoy the .220 Swift for what it was meant to be. The popularity of the Swift has slipped in the last twenty years and few factory rifles are now available in this caliber. There is no reason for this and I know the Swift will always have a strong and loyal following.

From time to time, we all encounter a primer that doesn’t go off. It’s normal to attribute the problem to a bad primer. But sometimes there are other explanations. George S., one of our Forum members, experienced a couple failures to fire, but he learned that the issue was his priming TOOL, not his primers. Here’s what George told us. There’s a lesson to be learned:
“I had issues with CCI 450s when I had my first 6BR barreled. I had probably three or four out of 20 rounds that failed to fire. the primers were dented but didn’t fire. I called CCI since I had bought a case of them. The tech was decent enough but had the audacity to tell me I was not seating the primers all the way in the pocket. I proceeded to let him know I had been reloading longer than he had been alive and I knew how to seat a primer.
Turns out that I did and I didn’t! I was using the RCBS primer tool I had used for years and the primers felt just fine to me. I finally decided to check the tool and since I had a new one I took the seating pins out and measured them. The seating pin on the tool I had been using for years was shorter by a few thousandths! I then used the pin from the new primer tool and darned if the primers that didn’t seat down to the bottom of the cup.
I switched to a K&M primer tool for seating the CCI primers and have not had a problem since. It was the combination of harder cup and lack of proper seating. I did call the CCI tech back and apologized for being an idiot.”
Another Forum member witnessed a problem cause by misuse of a priming tool: “I did … see a failure to fire on a Rem 9 1/2 primer only a week ago. That was in the new Rem muzzleloader that uses a primed case to ignite the pellets. After watching the muzzleloader’s owner seat his primers, I believe that it was operator error not the primer. He was seating the primer and then squeezing the priming tool so hard that his hands hurt after a few. We got that corrected.”
The 17 Mach 2 (aka “17 HM2″) is making a come-back. We’re glad. This high-velocity round fits actions and magazines designed for the .22 LR, so it’s an easy barrel-swap upgrade for most rimfire bolt-guns (semi-autos are more complicated). The 17 Mach 2 cartridge doesn’t deliver the velocity of the 17 HMR, but it is still way faster than a .22 LR. Expect 2000-2100 fps with 17 Mach 2 compared to 1250 fps for “High-Velocity” .22 LR ammo. And, importantly, 17 Mach 2 ammo is much less expensive than 17 HMR. If you shop around, you can get 50 rounds of 17 Mach 2 for about $8.50. That’s 43% cheaper than a better-than-average* $14.99 price of 17 HMR — a significant savings at 17 cents/round vs. 30 cents/round!
17 Mach 2 Major Selling Points:
1. 60% more velocity than typical “High-Velocity” .22 LR ammo.
2. 40% less cost than average 17 HMR ammo.
3. 17 Mach 2 OAL is compatible with .22 LR receivers and magazines.
17 Mach 2 — Best High Velocity Rimfire Bang for the Buck?
If you are looking for a capable, squirrel-busting round or a fun plinking round, you should definitely consider the 17 Mach 2, especially since CCI has committed to production of the little cartridge. CCI recently rolled out its “Gen 2″ 17 Mach 2 VNT Ammo with polymer tip (see top of article).
Considering that 17 HMR ammo is typically $15 to $17 per box, the 17 Mach 2 is a good value by comparison. It is available from vendors for about $8.50 per 50ct box. That’s $0.17 per round. When you consider overall “bang for the buck”, for many shooters, it makes sense to use the 17 Mach 2 rather than a 17 HMR. You save money, barrel life is a little longer, and the 17 Mach 2 is still a much more potent cartridge than the .22 LR. Check out this comparison, and note how the 17 Mach 2 has a much flatter trajectory than the .22 LR. For varmint shooting, the 17 Mach 2 is clearly the better choice.
And you can easily adapt a .22 LR Rifle to shoot the 17 Mach 2 just by changing the barrel. The magazine and bolt operation should work as the cartridge length, cartridge body diameter, and rim size is the same as the .22 LR.
Hornady’s 17 Mach 2 has a 2100 FPS muzzle velocity vs. 1255 FPS for “High-Velocity” .22 LR.
17 Mach 2 Rifle Reviews
Gun-makers have taken notice of the availability of 17 Mach 2 ammo, introducing new models chambered for this versatile little rimfire round. For a high-volume, small-species varminting, the 17 Mach 2 is much more effective than the .22 LR, and much less expensive than the larger 17 HMR.
New Savage A17 in 17 Mach 2
There are a number of reviews on new-generation 17 Mach 2 rifles. Recently Varminter.com reviewed the Savage A17 in 17 HM2. Editor Eric Mayer wrote: “This new addition to the A17 line comes at a time when the 17 Mach 2 round is experiencing a resurgence, with ammo now available from CCI and Hornady, including the lead-free NTX round from Hornady. This means … you don’t have to break the bank to buy a current, functioning, semi-auto 17 Mach 2 and you don’t have to … convert your 10/22.”
Eric shot four different types of 17 Mach 2 ammo, putting 1000+ rounds through the Savage. He was impressed: “I am very excited that Savage Arms has chambered their A17 rifle in the 17 Mach 2 / 17 HM2 round. After shooting the prototype, I can confidently say that this new A17 will become my go-to 17 Mach 2 rifle. This new rifle is a great option for varminters everywhere!”
Toggle Bolt Volquartsen Summit in 17 HM2
It’s rare for us to see a new rimfire that we’d really like to own, but the new Summit from Volquartsen fits the bill. This versatile rifle features a cool, straight-pull toggle bolt, similar to those on elite Biathlon rifles. You can see how this gun shoots in this informative 22 Plinkster video:
22 Plinkster Tests Volquartsen Summit Rifle in 17 Mach 2
The 17 Mach 2 (17 HM2) is making a comeback. Now leading manufacturers are offering this efficient little rimfire cartridge in some nice rifles. Both Anschutz and Volquartsen will offer new 17 Mach 2 rifles in 2019. The Volquartsen Summit features a lightweight, carbon fiber-wrapped barrel threaded 1/2-28 for brakes or suppressors. The Summit boasts a nice 1.75-lb trigger pull. The Summit’s CNC-machined receiver features a +20 MOA Rail. NOTE: The video shows a silhouette-style laminated wood stock. However, the Summit comes standard with a composite Magpul stock that actually works better for shooting from a bench.
*Note: The cheapest 17 HMR we found via nationwide search was $12.50/box, but MidwayUSA charges $19.99 for 50 rounds of most 17 HMR types. At most vendors you’ll pay $16-$18 per box for 17 HMR ammo.
We’ve found ten great discount/rebate programs. These specials can save you big bucks on pistols, shotguns, ammo, or bullets. Some of these rebates are worth $100 or more. For example you can Save $75 on a new S&W revolver, save $100 on a new Beretta pistol, or save $200 on a new Shotgun. Note: most of these promos are good through the end of May or June 2024, but some expire on March 31st — so check the dates.
Peterson Cartridge Company (“Peterson”) has released a lengthy, authoritative guide to the 22 Creedmoor cartridge, a popular wildcat based on the 6.5 Creedmoor or 6mm Creedmoor necked down to .224 caliber. We think the .22 Creedmoor would be a great long-range varmint cartridge, similar to the .22-250 Rem, but with a more modern, efficient cartridge design. In addition, some PRS/NRL competitors may turn to the .22 Creedmoor because it has less recoil and is flatter-shooting than the 6mm Creedmoor. In addition, .224-caliber match bullets are typically less expensive than heavier 6mm and 6.5mm projectiles. Less recoil, and less cost — what’s not to like?*
Along with load data, this article has specific sections dedicated to: Primers, Rifling Twist Rates, and Reloading Supplies. If you are considering building a .22 Creedmoor, we recommend you download the full Peterson .22 Creedmoor article, which is available in PDF format.
Peterson states, “Since its inception in 2007… the 6.5 Creedmoor has seen some pretty meteoric growth in popularity. That growth continues as of this writing, as the cartridge has now gone mainstream with hunters and shooters alike. As the popularity of the 6.5 Creedmoor has increased, so has the number of wildcat cartridges based off of it. Some of those popular wildcat cartridges are the 6mm Creedmoor, the .25 Creedmoor, and now the .22 Creedmoor. This data sheet will cover the .22 Creedmoor.
To help our customers, and anyone else who shoots .22 Creedmoor, we decided to create this Data Sheet and distribute it. [In this LOAD DATA Document] you will find four (4) common bullets, and four (4) common rifle powders used when handloading the .22 Creedmoor cartridge. We then took the different bullet and powder combinations and loaded them up to the SAAMI Maximum Average Pressure (MAP) for the 6.5 Creedmoor and 6mm Creedmoor cartridges, which is 62,000 PSI. [O]ur goal was to provide a wide spectrum of bullet weights and the powders used with them.
All of the following data was gathered by our ballistician in our indoor ballistics lab located in our factory in Pennsylvania. Although we were able to gather pressure and velocity data in our lab, we have NOT tested these loads for accuracy. Again, these loads are just designed to give shooters information regarding what velocity, a given bullet and powder charge combination, will produce the SAAMI Maximum Average Pressure (MAP) of 62,000 psi.”
Sample 22 Creedmoor LOAD DATA
IMPORTANT — Pressures can vary significantly with different Cartridge Overall Lengths (COAL). In addition, ANY change to ANY load components — primers, bullets, brass, powder — can affect pressure. Always load conservatively. In addition, because of variances in bore dimensions, some barrels may show higher pressures than others. Again, always start with conservative loads, well below MAX pressures.
*Actually there IS a potential downside — reduced barrel life. We expect that a .22 Creedmoor running hot varmint loads would experience shorter useful barrel life compared to a 6.5 Creedmoor. This is based on what we’ve observed with .22-250 and .22-250 Ackley barrels compared to our 6.5 CM barrels.
As does Lapua and some other leading bullet-makers, Barnes now uses radar to determine bullet BC values and ballistic data for its match bullets and ammunition. Barnes employs advanced Doppler Radar to record bullet speeds at multiple distances out to 1500 yards.
The Doppler radar system gathers thousands of data points as a bullet flies downrange. This radar data is used to generate a bullet specific drag curve, and then fed into a modern 6 Degree of Freedom (DOF) [ballistics software program] to generate precise firing solutions.
Determining Bullet Ballistics with Doppler Radar Data
How do you build better (more precise) ammo drop tables? With radar, that’s how. Barnes Bullets is using Doppler Radar to develop the drop tables for its Precision Match line of factory ammunition. The Doppler radar allows Barnes to determine actual velocities at hundreds of points along a bullet’s flight path. This provides a more complete view of the ballistics “behavior” of the bullet, particularly at long range. Using Doppler radar, Barnes has learned that neither the G1 nor G7 BC models are perfect. Barnes essentially builds a custom drag curve for each bullet using Doppler radar findings.
Use of Doppler Radar to Generate Trajectory Solutions
by Barnes Bullets, LLC
Typical trajectory tables are generated by measuring only two values: muzzle velocity, and either time-of-flight to a downrange target, or a second downrange velocity. Depending on the test facility where this data is gathered, that downrange target or chronograph may only be 100 to 300 yards from the muzzle. These values are used to calculate the Ballistic Coefficient (BC value) of the bullet, and the BC value is then referenced to a standardized drag curve such as G1 or G7 to generate the trajectory table.
This approach works reasonably well for the distances encountered in most hunting and target shooting conditions, but breaks down rapidly for long range work. It’s really an archaic approach based on artillery firings conducted in the late 1800s and computational techniques developed before the advent of modern computers.
There is a better approach which has been utilized by modern militaries around the world for many years to generate very precise firing solutions. Due to the sizeable investment required, it has been slow to make its way into the commercial market. This modern approach is to use a Doppler radar system to gather thousands of data points as a bullet flies downrange. This radar data is used to generate a bullet specific drag curve, and then fed into a modern 6 Degree of Freedom (DOF) [ballistics software program] to generate precise firing solutions and greatly increase first-round hit probability. (The 6 DOF software accounts for x, y, and z position along with the bullet’s pitch, yaw, and roll rates.)
Bullet-Specific Drag Curves Derived from Radar Data
Barnes’ advanced Doppler radar system can track bullets out to 1500 meters, recording the velocity and time of flight of that bullet every few feet along the flight path. The noteworthy graph below shows a Doppler Radar-derived, bullet-specific drag curve alongside the more common G1 and G7 curves:
Neither of the standard curves is a particularly good match to our test bullet. In the legacy approach to generating a downrange trajectory table, the BC value is in effect a multiplier or a fudge factor that’s used to shift the drag curve of the test bullet to try and approximate one of the standard curves. This leads to heated arguments as to which of the standardized drag curves is a better fit, or if multiple BC values should be used to better approximate the standard curve (e.g., use one BC value when the velocity is between Mach 1 and Mach 2, and a different BC value when the velocity is between Mach 2 and Mach 3.) Barnes’ approach to creating trajectory tables is to generate bullet-specific drag curves, and use that data directly in a modern, state-of-the-art, 6 DOF ballistics program called Prodas to generate the firing solution.

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:
3. Share a Ride to Matches. Fuel prices are on the rise — regular-grade gasoline is $5.13 per gallon in California now and around $3.54/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 $35.40 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 $0.58/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 $1500.00 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 consummating the sale. However, most demo scopes from name-brand manufacturers come with full factory warranties. EuroOptic.com and SWFA.com 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 under $0.18 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.
This cartridge was introduced by Winchester in 1935 in their model 54 rifle. A year later, it was added as a standard cartridge in the model 70. What might not be common knowledge to some reloaders is that the prototype for the Swift was developed in 1934-35 by Grosvenor Wotkyns by necking down the 250 Savage case, but in the end, Winchester chose the 6mm Lee Navy case for the foundation for this cartridge.
This approach works reasonably well for the distances encountered in most hunting and target shooting conditions, but breaks down rapidly for long range work. It’s really an archaic approach based on artillery firings conducted in the late 1800s and computational techniques developed before the advent of modern computers.
