Inasmuch as you'all thought enough of my article "The Enemy Of My Enemy Is My Friend" to make a sticky of it, I thought perhaps other articles I've written might be of interest too. So here's a second one.
If you'all find it interesting, I'll post others.
NOTES: This is the text of an article I wrote for "Precision Shooting" magazine six years ago. I no longer have the pics that went with the article. I have updated the text a little where I deemed it appropriate.
Aparently I'm too verbose. The site requires me to break this article into two threads.
MODERATOR: Much of the article is directed toward bolt action rifles. However, much is applicable to any type of action. If this is not the appropriate subforum for this article, feel free to move, or remove, it.

RB 101 INTRODUCTION TO RIMFIRE BENCHREST
1st SEMESTER
SYLLABUS
RB 101 is a "two-semester" course designed for shooters who have little or no experience shooting rimfire benchrest matches. It is also applicable to shooters with some rimfire benchrest experience whose scores are not as high as they desire. And the basic principles taught in RB 101 should have value in a multitude of shooting disciplines.
"First semester" topics address sources of KNOWLEDGE about rimfire benchrest and provide guidelines for EQUIPMENT AND EQUIPMENT SELECTION needed to compete successfully. EQUIPMENT SOURCES for selected pieces of equipment are also included at the end of the text.
"Second semester" topics include: ONE-TIME PREPARATIONS, --- PRACTICE DAYS, --- BEFORE EACH MATCH DAY, --- SHOOTING THE MATCH, --- and AFTER THE LAST SHOT'S FIRED.
Required readings for RB 101 include this article, the second semester article which will appear in next month's Precision Shooting, and six other Precision Shooting articles that are referenced in these articles.
The goals of RB 101 are to: encourage shooters to enter the rimfire benchrest game; to reduce the learning curve of new shooters by at least 12 months; and to increase the scores of experienced shooters.
KNOWLEDGE
Let's assume that you're starting from scratch into the rimfire benchrest game. You need both knowledge about the sport and appropriate equipment with which to compete.
Of the two, knowledge should be your first priority. Without adequate knowledge as a basis, you'll be hard-pressed to select good equipment. Fortunately, detailed knowledge is more available than ever before.
Much detailed information is available through "Precision Shooting", back issues. You can obtain some back issues of "Precision Shooting" on EBAY.
I've never found a book dedicated to rimfire benchrest; but a number of books have been written on centerfire benchrest shooting. Most of them contain tips that would apply to rimfire benchrest as well. Two books that I have found particularly valuable are:
"Extreme Rifle Accuracy" by Mike Ratigan
"The Benchrest Shooting Primer" Edited by Dave Brennen
Much valuable information about rimfire ammunition is provided in "Rifleman's Guide To Rimfire Ammunition" by Steven Boelter.
As you would expect, the internet is an invaluable source of information. One site devoted exclusively to centerfire and rimfire benchrest competition is Benchrest Central (www.benchrest.com). Another is Rimfire Accuracy. Reading rimfire forums daily will put you in contact with some of the leading shooters in the country. However, you may find some personal animosity among the participants that occasionally makes threads on the sites seem emotionally immature.
Several organizations sanction rimfire benchrest shooting competitions. Each organization has its own rules. And, some organizations are well represented in some areas of the country, but don't sponsor many clubs in other areas. Obviously it's essential to know the rules of the various organizations, and to know which organizations sponsor matches within your commuting distance. Fortunately, the Benchrest Central homepage contains links to all of the rimfire benchrest organizations. Simply click on their icons. You will be linked directly to each of their sites where you can read the rules and find a complete list of clubs and their schedules.
All of this "booklearnin'" is necessary; but it isn't nearly as much fun as going to a match. So visit matches near you, watch, ask questions, and learn.
This article is intended to be merely an overview. It cannot provide any semblance of complete, detailed information. (To do that would require an entire book.) I've already written several articles on various aspects of rimfire benchrest shooting for "Precision Shooting". I doubt if the esteemed editor would condone the redundancy of publishing their content again within this article. So, as appropriate, I'll just refer you to my other articles for more detailed information on particular subjects.
EQUIPMENT AND EQUIPMENT SELECTION
As you read the references I've given above, you'll probably come to two conclusions about equipment. First, there is quite a diversity of opinions. Second, not all advice is good advice. With that forewarning, I'm going to give you my opinions regarding equipment. As a minimum, this section should provide you with a fairly complete list of the equipment you need to compete. Whether you accept my opinions or not is completely up to you.
First, let me make a few general comments about equipment.
While it's theoretically possible to win with cheap, used equipment, it's also theoretically possible to win the lottery. (Let me know if you do either one!!!!) Buying the best equipment from the start will certainly be more expensive. However, the resale value of that equipment will also be higher. If you buy the best and later decide to dispose of it, you probably won't have lost any more money than if you'd bought cheap equipment that you can't resell.
You should consider all of your equipment to be one holistic system, assembled to shoot one shot at each of 25 bullseyes as accurately as possible within a limited timeframe. The system directly involved is the rifle with its tuner and tuner weights, scope, scope rings, rest(s), ammo, and windflags. Indirect, supporting components of the system include cleaning equipment and other ancillary items. You should consider every one of these components carefully. Poor selection of any component will reduce your ability to be competitive.
The list of equipment used by rimfire benchrest shooters who compete at the national level is a reasonably good indicator of what's competitive at that level. Fortunately, the American Rimfire Association website lists equipment used by competitors in their national competitions. However, when you view the lists, don't be particularly concerned about what the Winner used. Look more for equipment that is used by many of the better shooters. The ARA list includes not only the rifle's components, but also the brand of ammo used, and the name of the gunsmith who assembled the rifle --- a virtual cornucopia of information!!!!!!!!
Now let's turn our attention to all of the specific pieces of equipment that you need to compete (at least it's a complete list of all of the items that I need).
RIFLE --- Nearly all rifles are built from scratch by rimfire custom gunsmiths (or factory rifles that have had much customizing done to them by such gunsmiths). Rifles are composed of a receiver (with bolt), barrel, stock, and trigger. We really need to discuss each of these four components separately.
Based on national level equipment lists, the most popular receivers seem to be the Turbo and the Remington 40X with Anschutz, Winchester 52, Suhl, Hall, Swindlehurst, 2500X, and other custom actions also appearing with some regularity. These actions can be divided into two categories -- factory and custom. The factory receivers (Remington, Anschutz, Winchester, and Suhl) often must be reworked to eliminate the normal variations found in mass production in order for them to be suitable for benchrest accuracy. The Turbo receiver is arguably the most popular action. It is built expressly for rimfire benchrest. It is very rigid and manufactured to very tight tolerances. However, its small loading port may not be as readily loaded as other receivers. Each receiver has some advantages and disadvantages. Talk to experienced shooters and your trusted rimfire gunsmith before you select a receiver for your rifle.
Barrels from Shilen, Border, Lilja, Broughton, Mueller, and Hart are commonly found. All of these barrels are capable of winning. However, they may vary considerably from manufacturer to manufacturer in their rate of rifling twist, the shape of their rifling lands, and even the number of lands. Standard rifling twist is 1 turn in 16 inches. Some barrels have twists as slow as 1 turn in 18 inches. While this difference may not seem like much, the slower twist won't stabilize some brands of ammunition, especially in cooler climates. On the other hand, shooters in hot climates claim that with ammo it favors, a barrel with a slow twist will outshoot a faster twist barrel. Some barrels have "ratchet" rifling, utilizing lands with only one edge. Each land then tapers down on the other side to groove diameter. And some barrels have as few as two lands. All of these rifling styles have some devotees. As for myself, I'm somewhat of a traditionalist, I live in a cooler climate, and I favor barrels that like a variety of ammo. So, I use barrels with 1 turn in 16" twists and four to six rifling lands.
Stocks come from McMillan, Shenane, Stith, TM Stockworks, and a few others. Some shooters favor fiberglass or carbon stocks; others prefer wood. Each material has some advantages. Fiberglass and carbon stocks can be made physically lighter than wood stocks. And some benchrest associations have weight limits on rifles. Stock selection can have a major effect on the weight of the rifle. So make certain that you select a stock (and a barrel configuration) that will allow your finished, scoped rifle to meet the weight criteria for all competitions that you intend to enter. Fiberglass and carbon stocks are also relatively insensitive to warpage due to age or changes in humidity. And their buttstocks are often hollow, allowing you to add weight to change the balance and recoil characteristics of the rifle to suit your taste. Wood stocks, on the other hand, have a traditional beauty, and they are said to transmit less vibration during shooting, leading to better inherent accuracy.
Jewel triggers are nearly universally used. Benchrest triggers typically have pull weights of only a few ounces. So, specialized triggers are required. Few factory triggers can be set light enough.
TUNER ---As far as I can tell, approximately 100% of serious benchrest shooters have some type of tuner on their barrels. There are several brands of tuners on the market. But, they all have one thing in common -- they place significant weight ahead of the muzzle in a fashion that allows the location of the weight to be changed in very small increments. I'd suggest that you consult the rimfire benchrest forums for voluminous discussions on the subject. Then, ask your rimfire benchrest gunsmith's advice and take it.
SCOPE --- As you might expect, national equipment lists typically show some preference for Leupold scopes with good showings by Weaver, and Sightron. Shooters with bottomless billfolds opt for Nightforce and March scopes. Whatever brand you choose, I recommend a 30X to 40X fixed power scope with fine crosshairs and a 1/8 minute dot. Less than 30 power makes precise aiming more difficult. More than 40 power isn't needed and it increases the problems of mirage. The 1/8 minute dot only covers 1/16" at 50 yards; and it is more easily seen under poor lighting conditions than fine crosshairs alone.
SCOPE RINGS --- Key characteristics of scope rings are that: they must hold the scope rigidly without distorting or damaging it; they must be in perfect alignment with each other; they must be high enough to allow the scope's objective bell to clear the barrel and its eyepiece to clear the bolt handle; they must allow you to zero the scope near the middle of the scope's adjustment range; and they must not be unduly heavy. For me, Burris Signature rings have all of these characteristics. You can read about them and how I install them in my article "The One Shot Zero --- First Time, Every Time" in the July 2009 issue of PS.
AMMO --- Eley ammo is used by the vast preponderance of shooters. Lapua is the only other brand with any significant presence, and it is a far distant second. However, merely purchasing "generic" Eley ammo won't guarantee success. Eley comes in two bullet styles, flat-nosed EPS and round-nosed Semi Auto. And it comes in various grades with Tenex being the most expensive, followed by Match, and then Team. Rifleman's Guide To Rimfire Ammunition by Steven Boelter is entirely devoted to rimfire ammunition accuracy. It is well worth reading. And my article "Testing Conventional Wisdom About .22LR Ammo Accuracy" in the August 2009 issue of PS should give you additional food for thought.
REST(S) --- Rests are absolutely critical to the accuracy of the entire benchrest system. So their judicious selection is paramount. There are essentially two different styles of rests --- one piece rests, and two piece rests (where the front and rear portions of the rest are not connected). Each rimfire benchrest sanctioning organization has specific rules regarding rests. Make certain that you understand the rules for all organizations that you plan to compete under and select a rest that is legal for all of them. For a detailed discussion of types of rests and their advantages and disadvantages, see my article entitled "One- Piece Or Two --- The Great Rimfire Rest Shootoff" in the October 2009 issue of PS.
