I don’t usually reprint manufacturers’ ads and press releases here. I’m going to make an exception for this one. Winchester is now offering something very useful for those of you who teach shooting and firearms safety, whether in a class setting or one-on-one with friends and relatives.  Here it is verbatim, courtesy of Winchester:

Winchester® Launches Educational ‘Introduction to Ammunition-Ammo 101’ Series
East Alton, IL (September 21, 2022) — Winchester is launching its “Introduction to Ammunition-Ammo 101” series, a four-part series that includes custom illustrations and information in the following ammunition categories: rifle, pistol, rimfire and shotshell. 

“The basics of ammunition, that is what we want to deliver with the Ammo 101 series,” said Matt Campbell, vice president of sales and marketing. “With millions of people across the United States starting their journey in the shooting sports as new firearm owners, providing easy-to-understand information on ammunition types is one way we can help educate our customers.”

The Ammo 101 series provides a basic overview of shotshell, centerfire rifle, centerfire pistol, and rimfire ammunition, showcasing ammunition construction, components, calibers and common usage.

The Ammo 101 resource is free to download and is especially valuable for the thousands of shooting ranges and instructors nationwide who are introducing new entrants to the shooting sports and hunting. It is available as a free download at Winchesters.mediaassets.com (click on “Sell Sheets”).

Instructors can incorporate this into their training presentations, use as a handout or have it printed locally. For custom posters, metal signage, or questions on printing and sizing, Winchester does offer a printing resource available through REPCO Solutions.

  1. I downloaded the four parts and gave them to my grandson who is interested in shooting and a pre-engineering student in high school. I thought he could look them over quickly and have a good understanding about how ammunition works. I could have explained it but having the illustrations is much better. Thank you Winchester!

  2. Thanks, Mas, for this information. And a special well done for Winchester. This is the sort of thing that makes one company stand above others, and is not forgotten when seeking to purchase products. I try to reward good performance, and especially when going above and beyond, as Winchester is doing.

  3. With all the new shooters out there, having readily accessible basic information is very important. Much of what we take for granted is unknown to the neophyte. Having recently shot with a number of old friends, I was a bit taken aback by their lack of knowledge about ammunition, firearm operation, disassembly, cleaning, etc… These were people that had owned handguns for years, supposedly for self defense. Even scarier were ideas they had about the use of lethal force. I hope that I was able to impart a bit of knowledge in the short time we spent together.

    • “Much of what we take for granted is unknown to the neophyte.”

      Amen. I can’t count how many “first gun” folks I’ve heard at the gun counter saying, “It’s small, it’s so light. It’ll be easy to shoot.”

      Unfortunately Sir Isaac disagrees. “Small and light” = “Harder kick.” But we know that so well we forget to tell the new folks. It’s no fun watching someone try to shoot the 50-round Texas license practical with a five-shot “ultra-airweight” revolver.

  4. In just a year of supervising a shooting range I found that it was like any other place in some respects. In order to get certain people to follow the range rules, it was a good idea to interview all new arrivals immediately and make sure (1): That they were all QUALIFiED to be there (2): That they KNEW all the rules, and (3): That they would not be allowed to load up or shoot if they could not CONSISTENTLY follow the rules. Getting everyone to demonstrate full competence in maintaining constant muzzle control before they step up to the bench is critical. Some people have consistent difficulty with muzzle control, loaded and unloaded, especially if they feel stress, which is common. The main problem, standing or sitting, often seems to be not turning the body 90 degrees or so if necessary, vs. downrange, to handle the firearm so that the muzzle continues to be pointed correctly (not too high, low, or laterally) downrange. A dedicated “pre-shooting” training bench with on-the-spot instruction and plastic-dummy firearms demonstration before allowing first time range arrivals to go to the bench line might be a good idea, even if some arrivals are already safety experts. Range masters themselves can continually learn from interviewing shooters of extensive experience. TWO range masters who get along can be good to have, one to perform interviewing with some instruction, and one to command the firing line. I cannot count the times that people next to me at a shooting range got away with carelessly pointing handguns in my direction. Grrr, #%$&! One reason why soldiers and police in Israel, for example, supposedly carry chamber empty for safety. Not that I do, I still rely confidently instead on fully-loaded-carry, with my Ruger slide and Safe-Action-type safeties engaged.

  5. Downloaded all the parts, really good read, easy to understand. Would love a bit deeper dive in maintaining and cleaning your firearms, since not that many guides go into details about this – hell, I’ve seen so many young gun owners with really fillthy rifles, and when you ask em if they have some sort of gun cleaning kits they all be like “huh”, even though it’s extremely logical that you gotta clean that thing, and you gotta do it often…
