Seven Money-Saving Tips for Shooters

Let’s face it — economic times are still tough, so it’s important to save money whenever possible. Prices are going up, but wages aren’t following (for most of us). Here are seven ways shooters can save money on gear purchases and other shooting-related expenses.

1. Share a Ride to Matches. With gas costing close to $4.00 per gallon in many areas of the country, fuel has become a significant part of an active shooter’s hobby budget. Yet over 90% of shooters drive solo to matches, often in large, gas-guzzling trucks. If you drive 100 miles roundtrip to attend a match in a 20-mpg vehicle, you’re going to burn nearly $20.00 worth of gas total out and back. By simply sharing the ride with one fellow shooter you can cut your fuel expenditures in half.

2. Use Discount Codes to Save. It’s always smart to check for discount codes before you buy. In the Daily Bulletin, we regularly highlight important sales, and we provide discount Coupon Codes when available. By using discount codes when shopping online, you can typically save 10-15% on your purchases. For example, right now Sinclair Int’l is running a Labor Day Promo with discount codes. To find recent discount codes, just type in “Coupon Code” or “Discount” in the search box at the top of this page. If you can’t find a Coupon Code for your preferred vendor here, visit and/or Both those sites list current coupon codes, and covers thousands of vendors.

3. Gang Powder and Primer Purchases. Every time you order powder and primers you’ll need to pay a hazardous materials (hazmat) transport fee, which costs $25.00 – $30.00. If you do a joint buy with other shooters, you can ship more powder and primers on a single hazmat fee, effectively reducing your components cost. For example, if you buy 3 pounds of powder at $20/lb with a $25.00 hazmat fee your actual cost (before shipping) is $28.33 per pound. If instead if you buy 30 pounds of powder at $20.00/lb, the actual cost with hazmat is just $20.83 per pound. Moreover, when you buy in bulk, you can usually save significantly on the powder itself. At Powder Valley, one pound of Varget costs $19.75, while an 8-lb jug of Varget costs $139.50 ($17.44/lb).

4. 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. and are two respected vendors that offer a good selection of demo optics.

5. Train with Rimfire Rifles. The true cost of shooting a match-grade centerfire rifle, when you consider barrel wear, approaches $1.00 per round. READ Shooting Cost Article. By contrast .22LR Wolf Match Extra costs just $0.17 per round and other good rimfire ammo can be purchased for even less. 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 .22LR 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.

6. Check Out the Forum Classifieds. There are great deals to be found every day in the AccurateShooter Shooters’ Forum. The latest deals are listed on our home 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

You can find some great deals on complete rifles, optics, and reloading gear in our classifieds. Before purchasing, however, read our Advice to Online Classifieds Shoppers.

7. Take Advantage of Factory Rebates. There are some amazing rebates available right now from quality manufacturers such as Bushnell, Leupold, RCBS, Sightron, and Zeiss. You have to be a bit wary because rebates are typically used to move less-popular merchandise. But some rebates, such as the current RCBS $50.00 rebate, apply to very wide range of merchandise, so it’s hard to go wrong. Just make sure that, when you buy a product, you retain the sales slip and the original packaging. To qualify for the rebate, you may need to mail in a product identification code found on the box, along with your original sales receipt.

David Rolls and The Slope Doper

By Dr. Jim Clary

Rolls Slope DoperOne cannot discuss one of the most useful tools for long range shooters, The Slope Doper, without saying something about its inventor, David Rolls. David was a bold man, bigger than life, who dedicated his life to the service of others. Yet, he was full of fun and a little mischief. He had little tolerance of fools (a man after my own heart), but had great respect for those who deserved respect. It was a loss to all when he passed away in August 2008 at the young age of 61. That being said let me tell you of how he lived and what he accomplished with The Slope Doper.

David Rolls’ Background
David worked for years with the Baltimore City Fire Department as a firefighter and paramedic, retiring at 45. Not being content to sit around, he applied for a job with the Sheriff’s Department of Mineral County, West Virginia and graduated from the state police academy. No small feat for a man of any age, let alone one in his forties. David rose to the rank of Sergeant and held that rank until his passing. As a firefighter, paramedic and police officer, he was the kind of man you would want if you were in a tight spot. He never backed down when it came to helping others. Throughout his life he was active in the Boy Scouts and community activities. He was a lifetime member of the NRA holding the status of Golden Eagle and Certified Firearms Instructor.

As a shooter, David was intensely interested in tactical competitions and was a member of the American Sniper Association. Long distance tactical shooters are frequently faced with the problem of making adjustments when shooting uphill or downhill, as well as windage and normal bullet drop. Chucks Hawks provided a superb discussion of the effects of uphill/downhill shooting for the hunter. I strongly urge every reader to look up Chuck’s article to better understand the problem.

Even knowing that we will be shooting over our target (or at best higher than our aiming point), most hunters do not know how to make the required adjustments in the field. Something had to be devised that could be used quickly in the field by the average hunter. Enter David P. Rolls!

Slope Doper Debuts in 1998 at Storm Mountain
After a great deal of thought, David showed up at the Carlos N. Hathcock II Charity Sniper Competition at the Storm Mountain Training Center in 1998 with a prototype of his Slope Doper. It was somewhat crude by comparison to the current day production model, consisting of a laminated paper protractor with a weight and string, but it worked. It allowed a shooter to determine the impact point of his bullet when shooting at any angle. David had succeeded in combining the science of mathematics with the practicality required for field use. It should be noted that military shooters have used protractors for years, but they had to subtract numbers to arrive at the correct angle. Dave’s invention placed the zero degree point at the top of the arc, virtually eliminating the possibility of error. Ever the perfectionist, with an eye to the future, he asked his best friend, Fred Fischer to design a “professional” version with AutoCad, which Fred gladly did. Fred also had contacts with a manufacturer who happened to be a shooter and they were off. Fred still chuckles when he remembers all of the last minute changes that Dave came up with, but at least they had the basic artwork locked into the AutoCad program to go into production. The rest is history.

Rolls Slope Doper

The Quantico marine sniper instructor who was the first military member to see a production version of the Slope Doper (and incidentally a member of the two-man team who won the Carlos Hathcock Sniper Competition) was impressed enough by it to remove his personal protractor from his data book and replace it with the Slope Doper David gave him. The Slope Doper is now standard issue with the Marine Corp sniper weapon system; The Slope Doper is packed with each rifle and its accessories. The pointer is easily replaceable with string and a weight if it is lost and the printing on both sides is actually fire resistant. It is mil spec and made to withstand combat conditions. It is aluminum rather than plastic, so that it will not break in cold conditions.

To understand how the Slope Doper works, it is best for me to let David tell you in his own words:

To begin with, you must understand that when you shoot up or downhill, gravity has a diminished effect on your projectile such that if you do not make any adjustment for angle, you will likely shoot over your target. This applies at long distances (greater than 300 yards) at slight angles and at severe angles (greater than 30 degrees) at lesser distances. With slight angles at short distances the adjustment may not be enough to worry about. The Slope Doper is a photo etched, anodized, aluminum plate that has two scales inscribed along an arc. The first scale tells you the angle in degrees, the inner scale gives you the cosine of the angle (what I call the “Slope Angle Factor”) at 10 degree intervals.

To use the Slope Doper, you must first know the range to your target. Next you have your partner (guide) hold the Slope Doper along side the bore centerline of your rifle while you take aim and read the Slope Angle Factor. If you are alone, you can sight your target along the top edge of the Slope Doper and capture the pointer with your thumb and then read the Slope Angle Factor. If you are not at an exact Slope Angle Factor, it is easy to interpolate. Now take the known distance and multiply that by the Slope Angle Factor. The answer you get is the effective range. You should now shoot as if the actual distance is the lesser distance (at 30 degrees, a Slope Angle Factor of 0.87, 500 yards becomes 435 yards). All other environmental factors, like wind, are still in effect at the actual distance (500 yards of wind is still 500 yards of wind).

To make my life easier, I attached some Velcro to the back of my Slope Doper and on the forend of my rifle. After using my rangefinder for distance, I simply point my rifle at the target, capture the pointer with my thumb, read the Slope Angle Factor, make a quick mental calculation and shoot. If you are an experienced shooter with a scope that has a mil dot reticule, the back of the slope doper has your ranging formulas. The Slope Doper is a must-have for every person who hunts in mountainous country, from the Appalachians to the Rockies. It will help prevent you from missing your quarry. It is a bargain when compared to the $300 – $500 we pay for our rangefinders and binoculars. You can purchase the Slope Doper directly from the Slope Doper Website for $24.95 plus $5.00 shipping (PayPal or mail-order). U.S. Tactical Supply also sells the Slope Doper for $24.95.

A final note: I was watching the Outdoor Channel last week and watched a hunter on a ridge shoot over a 6×6 bull elk in the valley below. The elk disappeared, and the show ended with the hunter and guide talking about the thrill of the chase, even though they missed the elk. Good for public relations, but not so good for the freezer. They should have had The Slope Doper!
