A new Vortex video series, Cartridge Talks Comparisons, looks at multiple variables along with ballistics gel tests to determine the comparative performance of popular cartridge types. Each Month, Cartridge Talks will examine and test two popular cartridges, comparing their head to head performance. In Episode 1, Vortex Nation™ hosts Mark Boardman and Ryan Muckenhirn pit the 6.5 Creedmoor and .308 Winchester cartridges against each other, examining projectile performance. Mark and Ryan then make conclusions about the applications best suited to each cartridge type.
Cartridge Comparison 14-minute video, Highlighting Ballistic Gel Testing
This first Cartridge Talks Episode pits the 6.5 Creedmoor against the .308 Winchester in a head-to-head, ballistics gel-induced bullet battle. Ballistics (drop/drift), penetration ability, terminal performance and other variables are tested with a variety of tools and tests. Viewers are invited to check out Episode 1, and suggest future cartridge battles in the comments section.
Here is the full 67-minute 6.5 Creedmoor vs. .308 Win Cartridge comparison video:
“With the myriad of cartridges available to the big game hunter, picking which chambering is best for you and your application can be a daunting task,” says Muckenhirn. “In Cartridges Talks, we put our biases on the shelf and put as much scientific process to this as possible. From ‘shootability’ and accessibility, to terminal performance as observed in ballistics gel, Cartridge Talks wades through the numbers and figures with you, loads you up with the pertinent information, and helps you select the ideal cartridge for your next hunt!”
We know that Competition Machine (Gary Eliseo) makes great chassis systems and Pierce Engineering (John Pierce) makes great actions. But sometimes a project comes together even better than one can imagine. The folks at Pierce Engineering crafted an Eliseo Tubegun that displayed some mind-blowing accuracy during initial testing. This was a special rifle built to a client’s spec in .22 PPC.
After his team completed the rifle, John Pierce took the Tubegun to the range to make sure everything was working right. The rifle was chambered for the .22 PPC, a known accuracy cartridge. Would this cartridge shoot in this gun? Heck yeah was the answer! The first two shots out of the gun were touching. That was promising enough. But then John drilled a five-shot group that was basically one hole! Here is that target. First two shots upper left, then the five-shot group below and to the right. Chassis-maker Gary Eliseo commented: “that’ll do just fine…”
Disclaimer: John shot some more groups with this Tubegun that were definitely NOT one-holers. That first five-shot masterpiece could not be duplicated. However, we’re told that the rifle shot other groups in the 2s, 3s, and 4s — impressive performance for a rifle designed for prone and position shooting. This shows how well the Pierce action mates to the Competition Machine chassis.
And if the owner ever wants to show off a “wallet group” for his new rifle — well he’s got that, thanks to John’s great trigger-pulling and rifle-building. Using On-Target software we measured that five-shot group at 0.189″ (see photo at right). That’s crazy small for a new gun with zero load development. That’s also a testimony to the quality of the Norma .22 PPC brass.
Why the .22 PPC Chambering?
The customer owns other Eliseo Tubeguns, but wanted something that combined extreme accuracy with very low recoil. He also wanted to be able to shoot factory brass without fire-forming. Norma makes very high-quality .22 PPC cartridge brass that is an easy load and shoot solution. In fact the folks at Pierce Engineering custom-loaded a quantity of .22 PPC ammo for this Tubegun and shipped it off to the customer along with the new rifle. NOTE: Loading ammo is not something that Pierce normally does, but this was a special client request.
Norma .22 PPC Cartridge Brass is available from Bullet Central for $75.99 for FIFTY (50) cases. That works out to $151.98 per 100. Yep that’s pricey considering that 6 years ago this same Norma brass was just $88.88 per 100 cases. But we have seen significant inflation in nearly all premium brass offerings.
This shocking Revolver Kaboom resulted from “user error”. Our friends at Midsouth Shooters provided this cautionary tale, noting that you must ALWAYS be careful when hand-loading any ammo. Check your loads and don’t have multiple powder containers in your reloading area.
“Ever wonder what happens when you don’t pay attention to detail? A word of advice from the reloader who brought this in — always double-check the load data.
Thankfully, the shooter was unharmed in the explosion. A live round we recovered from the remaining portions of the cylinder contained 12.8 grains of powder. The shooter had multiple powders on his bench and was unable to recall which one had been used while loading.” — Midsouth Shooters
How to Avoid Kabooms
1. Never have more than one powder container open on your reloading bench at the same time — when you are finished with a powder, seal the bottle and put it away.
2. If there is already powder sitting in your dispenser, and you’re not 100% sure what it is — throw it out. We suggest, whenever you fill a powder hopper, put a piece of paper in the powder hopper with the name of the powder and the date.
3. When loading a new cartridge or when using a new powder, get load data from more than one source. Always load conservatively to start!
4. Always double-check your Load Data before starting the loading process.
5. In short handgun cases, bullet seating depth can make a BIG difference in pressure levels. Be sure to check your Cartridge OAL.
Forum member Kevin (aka “N10Sivern”), revealed he needs some help with a compulsion — a compulsion to keep buying more and more guns and ammo. Particularly ARs, all shapes and sizes of ARs. Way too many ARs. You could say he has an ARdiction….
In a Forum Thread from a few seasons back, Kevin posted:
“I may need an intervention. Trying to clean my office and pulled this stuff out. I’m missing an AR10 lower somewhere and an AR15 upper. I’ll find them before the day is done. I have a big box full of parts as well, and 4 barrels still in the cardboard tubes. Sigh. This is gonna be a lot of Cerakoting for me.”
Another Forum member said: “For the love of God, man. Delete this thread lest you be accused of hoarding!”
Kevin replied: “I guess I am hoarding a little. But it’s good hoarding right?”
And then he posted this “Mail Call” photo:
Kevin’s caption: “It only gets worse. Mail Call today: 20″ .308 Ballistics Advantage barrel, 26″ Savage 25-06 barrel, 700 pieces of .38 special, 300 pieces of .357 magnum, 500 pieces .308 Win, gas tube, Hornady Modified Case Gauge. I have more crap on the way too.”
Forum Member’s Chime In…
Kevin’s “Need Intervention” post drew plenty of comments from other Forum Members:
“God! It is so refreshing to see that my illness is widespread with little hope (or desire) for a cure. I smiled reading each post.” — Gary0529
“You know you have a problem when you open a drawer and find components you forgot you bought.” — JoshB
“It’s not hoarding if you intend to use it. Says he who has 12,000 primers.” — Uthink
“I guess I’ll go ahead and volunteer to help you with your obviously much needed intervention… send me the pictured items and then you’ll no longer have to deal with those nasty temptations. Just think about it, you’ll have less clutter in your office plus you’ll not have to fret over the need for any cerakoting either. I’m just one human being volunteering to help out another fellow human who needs help!” — PikesPG
For today’s Saturday at the Movies special, we provide a selection of videos showcasing rifle and pistol cartridge types — from tiny .17 caliber cases to huge 20mm cases. Two of the videos use advance computer animation to provide 3D views of dozens of cartridge types. Then there are some expert commentaries by Jerry Miculek and Ron Spomer discussing the characteristics and performance of various cartridge types. Finally, we provide two videos that discuss rimfire cartridges and show how .22 LR rounds are produced in a modern CCI factory.
90 Different Rifle Cartridge Types in Computer Animation
In this rifle ammunition comparison animation there are 90 different cartridge types, from very small (.22 Flobert) to very, very big (20mm Vulcan). This video employs sophisticated, 3D CAD animation to showcase 90 different rifle cartridges, one after the other, in sequence. It covers from .17 Caliber up to 20mm. Obviously a lot of time and effort went into this video, but it really is cool to see so many different cartridge types in one 3.5-minute video.

In this 15-minute video, hunting expert Ron Spomer examines a variety of standard and wildcat cartridges from .17 caliber all the way to .338 caliber. For each caliber, Ron picks a flat-shooting “winner” and provides some ballistics comparison tables. This video is quite popular, with over 550,000 views on YouTube.
Ammo Types and Calibers — Jerry Miculek Explains the Basics
In this video, legendary shooter Jerry Miculek talks about popular types of pistol and rifle ammunition and the various bullet options used for plinking, competition, and self-defense. Jerry, one of the greatest pistol shooters on the planet, provides useful insights on cartridge selection and bullet choices. Jerry notes: “There are a TON of different types of ammunition” so he explains the basics. And Jerry answers common questions such as: “What is the difference between ball and hollow-point bullets?” and “What type of gun takes rimmed cartridge versus rimless?”.
.22 Caliber Rimfire Cartridges — Some Key Facts Revealed
We recommend all .22 rimfire shooters watch this video from Old English Outfitters. It explains some important facts and clarifies some common misconceptions about to .22 caliber ammunition. To learn more about modern .22 LR rimfire ammo, we also recommend the video below, which shows how CCI .22 LR ammunition is manufactured, start to finish.
BONUS Video — How .22 LR Ammunition Is Made
YouTube host 22Plinkster toured the CCI/Speer production facility in Lewiston, Idaho. While touring the plant, 22Plinkster was allowed to capture video showing the creation of .22 LR rounds from start to finish. This is a fascinating video, well worth watching.
This revealing video shows all phases of .22 LR ammo production including cupping, drawing, annealing, washing, drying, head-stamping, priming, powder charging, bullet seating, crimping, waxing, inspection, and final packaging. If you’ve got ten minutes to spare, we really recommend you watch the video from start to finish. You’ll definitely learn some new things about rimfire ammo.
Ruger Super GP100 Revolver in 9mm Luger (9x19mm)
Wouldn’t it be cool if you could shoot your 9mm semi-auto pistol ammo in an ultra-accurate revolver? Well you can. Ruger adapted its existing Super Redhawk frame to create the Super GP100 9mm Luger (9x19mm) revolver. As you can see, the Super GP100 9mm features a stubby 8-round PVD-coated cylinder to better fit the 9x19mm round. According to Guns.com the 9mm GP100 “uses a cylinder and extractor cut for moon clips to speed up reloading [and] sports a 6-inch half-lug sleeved and shrouded barrel with an 11-degree target crown[.]”
Watch this GunBlast video review to see how this unique Ruger 9x19mm wheelgun performs. Reviewer Boge Quinn said this a “competition grade gun” with nice fit and finish. Out of the box the Super GP100 9mm had a 9.5-lb double-action pull and a 4.5-lb single action trigger pull. It took a while for the pull to smooth out Quinn noted. Also, he said that if you do NOT use the supplied moon-clips it is awkward to remove the spent cartridges: “You don’t have to use a moon clip, but I don’t know why you wouldn’t… it just works great that way.”
The 9×19mm Parabellum (aka 9mm Luger) cartridge was introduced in 1902 by German weapons manufacturer Deutsche Waffen und Munitionsfabriken (DWM) for the Luger semi-auto pistol. Now 120 years later, Ruger brings us a sturdy, 6″-barrel revolver for this popular cartridge. Ruger adapted its existing Super Redhawk frame for this Super GP100 9mm revolver. In this video, Ruger engineer Mark Gurney explains the features of the Super GP100 9mm revolver:
Super GP100 9x19mm Features
Triple-locking cylinder locked into the frame at front, rear and bottom for more positive alignment and dependable operation.
High-strength stainless steel cylinder is fluted and shortened to reduce overall mass and increase rotational speed. Cylinder has PVD finish for durability and ease of extraction.
Polished and optimized internals, a centering boss on the trigger, and centering shims on hammer deliver a smooth double-action trigger pull with crisp/consistent let-off.
Cylinder and extractor are cut for moon clips to speed reloading during intense competition. Ships with three full moon clips and moon clip tool. The ejector and chamber mouths have a light chamfer to aid loading with moon clips.
Hogue hardwood grip is hand-finished for a smooth, polished feel. Grip frame accommodates a wide variety of custom grips.
Transfer bar mechanism provides security against accidental discharge.
Cold hammer-forged barrel has precise rifling for accuracy and longevity.
Barrel features 11° target crown for competitive-level accuracy.
You’ve heard the adage — “The couple that plays together, stays together.” Here’s a story about a talented husband and wife who compete together in precision rifle matches. Shooters Tim and Regina Milkovich have done well in competition, including both placing in the Top 10 at the popular CowTown Accurized AR Match a while back. Regina took third with a nearly-clean run, dropping only one shot on Stage 5 to end with 49 points and an overall time of 49.50. Tim followed closely behind, placing sixth with 48 points and a time of 37.95.
This match, held at the CowTown Range in Peoria, Arizona, is designed to test and build shooters’ long range skills. Shots are taken from normal PRS-style positions and supports. Each match consists of five stages with targets ranging from 100 to 700 yards. Each stage has a 20-round maximum, and the match typically requires 40 to 50 hits.
Tim and Regina, who are both sponsored by Nosler, can often be found competing together at individual and team matches. At this match, both shot ARs chambered in .223 Rem loaded with Nosler .22 caliber 77gr Custom Competition bullets.
This video is from a past Cowtown Accurized AR match.
Regina is a Top Female PRS Shooter
Regina is one of the top female precision rifle competitors in the country. She is one of only two women to ever win a national-level Precision Rifle Series (PRS) match. Just a few years ago Regina was a novice in the PRS/NRL game. Now ranked as a Master Class shooter, today she is a respected, top-level competitor.
Time is a Veteran Who Shoots Many Disciplines
Tim is a military veteran with service in the U.S. Marine Corps, U.S. Army, and U.S. Air Force. He has been shooting competitively since 1986 in multiple disciplines including Pistol Silhouette, Bullseye Pistol, USPSA, IDPA, and 3 Gun. Tim has a Master Class ranking in most of the disciplines he shoots.
Tim also shoots bolt-action rifles. Below are his 6.5×47 Lapua cartridges loaded with Nosler 140gr RDF bullets and Varget powder. Photos from Tim Milkovich Facebook Page.
AR-Type Rifle Event in April at Camp Atterbury, Indiana
The NRA Competition Shooting Division is launching the America’s Rifle Challenge, an all-AR-based program to build and test skills for shooters of all levels. On April 19, 2025, at Camp Atterbury, Indiana (south of Indianapolis), the NRA will hold the America’s Rifle Challenge, a one-day, AR-based competition with two levels giving participants a fun intro to the action shooting sports with AR-15 type rifles. The NRA will provide prizes and awards for competitors and winners (plus a free lunch). Match Fees are $45 for NRA Members and $55 for non-members.
After the action concludes, the NRA will provide a FREE BBQ lunch for all competitors and one immediate family member or friend. American Rifleman TV and ShootingUSA will be filming the match and conducting interviews with competitors and spectators.
America’s Rifle Challenge Event Levels:
Level 1: The Level 1 course of fire is conducted from 10 out to 100 yards with competitors firing from different positions under time constraints. Level 1 is intended for AR owners new to competitive shooting. This event focuses on building skills to improve accuracy, speed, and mechanics. L1 matches are conducted from 100 yards and inward, with a balance of both time and accuracy being measured in every event. There are currently five total stages of fire in this match, with more in development. NOTE: Level 1 is limited to the first 32 competitors (4 squads). Space in level 1 is limited, so sign up quickly.
Level 2: The Level 2 course of fire covers the full spectrum of what is possible with an AR. L2 matches are conducted from 500 yards inward. Competitors will face a variety of stages designed to test skills — shooting and moving, positional shooting skills, long-range precision, speed, stage planning, and use of barricades, as well as close-quarters exercises. Level 2 offers a higher round count and more dynamics to the stages. NOTE: Level 2 is limited to the first 60 competitors (6 squads).
America’s Rifle Challenge Match Gear Requirements:
AR rifle in .223/5.56, .300 Blackout, or .308 Win

AR-platform rifles can be maintenance-intensive beasts. But some AR owners make the situation worse by not regularly cleaning important small parts, or by using too much oily/greasy lubricants in the wrong places. A properly maintained and lubricated AR15 can shoot hundreds of rounds (between cleanings) without a problem. If you learn where (and where not) to apply lubricant, you’ll find that your AR will run more reliably and the task of cleaning the bolt and bolt carrier will be less of a burden.
Here is a good video that explains AR-15 Cleaning and Maintenance. In this 30-minute NSSF video, Gunsite Academy instructor and gunsmith Cory Trapp discusses the proper way to clean and maintain the AR-15 carbine. Very knowledgeable, Trapp provides rock-solid advice for AR owners. Along with cleaning procedures, this video explains how to inspect key components and how to function-test your AR before each shooting session.
If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. Here’s another good video that explains how to properly disassemble and clean AR-platform rifles.
Take-Down and Full Cleaning of AR15 by Jerry Miculek
Here ace shooter Jerry Miculek takes down and cleans an AR-platform rifle belonging to his daughter Lena. This is a good video because Lena’s rifle was “run hard and packed up dirty” so you can see where carbon and grease build up. This 35-minute video is very thorough. Jerry is one of the nation’s top action carbine shooters, so listen carefully to his advice on cleaning and lubrication.
Wouldn’t it be nice to have a print resource that has hundreds of true-size cartridge illustrations, plus technical descriptions of thousands of popular cartridge types? That could be a real time-saver. It’s no wonder this Ammo Encyclopedia book is an Amazon category best-seller.
If you’re a serious shooter, the latest 7th Edition of the Ammo Encyclopedia belongs in your library. This 928-page book by Charles Priore Jr. and Lisa Buening is probably the most comprehensive and up-to-date book in print covering current and classic cartridges and shotshells. The Ammo Encyclopedia is a massive resource work. The 7th Edition, released in October 2022, now boasts 100+ chapters, covering thousands of handgun, rifle, and shotgun cartridges. This 928-page softcover book sells for $39.99 on Amazon (#ad). That’s a good deal — 20% off list price.
One of the best features is a full-color section depicting actual size drawings of over 300 current rimfire/centerfire cartridges and shotshells. You won’t find that many “life-size” cartridge drawings in one place even on the internet. Cartridge profiles and ballistic charts have been expanded to include many new factory cartridges. An expanded Trademark Index lists contact information for all current ammunition manufacturers.
For the 7th Edition, over 150 cartridge types have been added. And dozens of previously proprietary cartridges now have individual profiles. An expanded color section shows current centerfire, rimfire, and shotshell cartridges in full color. Plus updated Ballistic Tables provide muzzle velocity, dimensions, and page numbers for the corresponding cartridge profile pages.
Comments from guys who bought the book:
“[The Ammo Encyclopedia is] better than Cartridges of the World. Much better editing and more accurate.” — John Guibert
“The amount and depth of detail provided is beyond impressive. An enormous amount of time and thought went into this latest version of the Ammo Encyclopedia.” — BW Kreisler
“I have many books on firearms and ammunition acculmulated over a few decades. This is by far the best and most comprehensive book on ammunition that I have ever seen. It is a must have reference source for everthing ammunition whether for current or obsolete and the history behind them.” – Eric
Disclaimer: John shot some more groups with this Tubegun that were definitely NOT one-holers. That first five-shot masterpiece could not be duplicated. However, we’re told that the rifle shot other groups in the 2s, 3s, and 4s — impressive performance for a rifle designed for prone and position shooting. This shows how well the Pierce action mates to the Competition Machine chassis.
