Today we feature a modern switch-barrel PRS chassis rifle set up for quick changes between 6mm Creedmoor and 6.5 Creedmoor barrels. The owner, Forum member Jeff Cosgrove (aka “Punkur67″) uses the 6 CM barrel for competition, favoring the reduced recoil over its 6.5 mm big brother. He does use the 6.5 CM barrel for practice (given its better barrel life). The 6.5 CM barrel also gives him the chance to shoot a variety of factory 6.5 Creedmoor ammo.
- Terminus Zeus action with Quick Change (QC) barrel option.
– 6mm Creedmoor Pre-Fit Bartlein Heavy Varmint 400MODBB barrel for matches
– 6.5 Creedmoor Pre-Fit Benchmark Heavy Palma barrel for training
– MPA BA Competition chassis with full weight kit
– Zero Compromise Optic ZCO 5-27x56mm FFP scope
– TriggerTech Diamond trigger
This rifle represents an evolution for Jeff. Each step along the way in his PRS journey, he has learned more about what he wants and needs in a competition rifle. And what you see here, from the $3760 ZC527 scope to his high-tech reloading equipment, represents pursuit of excellence. Jeff even created a modern, spacious man cave/reloading center in his new house (photos below).
Quick-Change Barrel System with Terminus Zeus QC Action
This rifle has two pre-fit barrels that work with the Terminus Zeus QC Action for fast and easy barrel swaps. To remove a barrel, you simply release two tension screws on the front of the action and then unscrew the barrel. To swap in a different pre-fit barrel, reverse the process and then tension the screws. The Terminus Zeus is 3-lug receiver with 60° bolt and integral recoil lug. Both the receiver and bolt are DLC-treated. Jeff reports this action is extremely smooth and has met all of his expectations. Some other Zeus features are threaded trigger pins for quick/easy trigger installation, and a roller-tipped cocking piece.
PRS Discipline Offers Fun, New Challenge for Long-Time Shooter
My name is Jeff Cosgrove, I live in Winchester, California and do commercial heating and air conditioning. I have shot for 20+ years but I found my interest in shooting was dwindling over time. I got somewhat bored with shooting paper at 100 yards or plinking cans out in the desert. About 18 months ago I decided I wanted to shoot long range. I picked up a used MPA in .300 Winchester Magnum and started shooting long range with a new buddy. That day I fell in love with guns all over again with more intensity than ever.
How I Got Started in PRS
With that new .300 WM I soon found my reloads were not up to my expectations (high ES/SD), so I purchased all new reloading hardware. One of my purchases was a used Benchsource Annealer. The guy I bought that from asked if I had ever tried PRS and he invited me to check out a match. So I went to a local PRS event as a spectator. I looked at many rigs on the firing line and took notes. By the end of the day I knew this was something I really wanted to do. I then acquired a used chassis rifle that I thought would work well for PRS. I went to a PRS match the following month but shot poorly.
After working with that first PRS rifle, a 6.5 CM with Stiller Tac30 action, MDT chassis, and Proof Carbon-wrapped barrel, I quickly learned that gun did not handle and balance the way I hoped.* It was too light in the front, the ergos were poor, and scope eye relief was not optimal. So I decided to build my own GEN 2 PRS rifle. This is the story of how I put together my new switch-barrel rig that I now use in competition.
PRS Rifle and Gear Selection — Learning What Works
Barrel availability was limited given the current shortages. Luckily I was able to obtain a 6mm Creedmoor pre-fit Bartlein Heavy Varmint 400MODBB from Southern Precision Rifles. The 6mm Creedmoor is notorious for being a barrel burner cartridge so I went with the special 400MODBB metal. Bartlein says that barrel life expectancy is 1.5 to 2 times longer than the standard 416 grade steel. I also purchased a 6.5 Creedmoor pre-fit Benchmark Heavy Palma barrel for training (Source: Straight Jacket Armory). With the Terminus Zeus quick change system I am able to swap from my match barrel to my trainer barrel in just a couple minutes. I loosen two set screws, unthread the barrel, thread the new barrel on, and torque the set screws to 10 inch-pounds. This also affords me caliber options in case I’m in a pinch for ammo. If I have some 6.5 CM loaded up and don’t have time to load 6mm Creedmoor for a match, then I’m covered.
For the trigger, I went with a TriggerTech Diamond Pro curve model. I have Timney, Jewell, and TriggerTech triggers in other rifles. I like them all but I liked the feel of the TT Diamond the best so that is what I used on this build. I set my triggers around 18-20 oz. — I am not a fan of ultra-light trigger pulls.
MPA BA Competition Chassis with Added Weight
I went with an MPA BA Comp chassis with full internal and external weight kit. I also have Gray Ops external weight on the handguard. I had the same chassis on my .300 WinMag and felt very comfortable with it. I took a PR1 class and found that, with a different gun, I had to force a comfortable hand position for proper trigger pull. After that class I grabbed my MPA and my hand fell in to the perfect position. I did not need to hunt or index my hand with the MPA. The built ARCA rail (RAT) lowered the rifles center of gravity more than my old setup with the ARCA rail bolted to the bottom of the handguard. With the current configuration, the rifle weighs in at 24 lbs. and balances three inches in front of the magwell. I now have the flexibility to add, subtract, or move approximately 6 lbs. of weight.
The Attraction of PRS/NRL Practical Competitions
I really enjoy PRS-style shooting because there seems to be a new challenge every time you compete — no matter what. With PRS I am shooting many different positions and ranges with the pressure of a stopwatch. This keeps things interesting for me. I have taken a few training classes to help establish good, clean fundamentals.
Jeff says it is hard to practice for the many unconventional shooting positions at PRS matches.
My biggest challenges so far have been: 1) building stable shooting positions that I have not practiced enough; 2) proper equipment selection; and 3) time management. Regarding the shooting positions — PRS/NRL is not like F-Class where you can always practice from one position. And it’s hard to practice for unusual set-ups (barriers and positions) you’ve not encountered before. Concerning equipment — you need some experience in the game to determine what really works best for you.
Innovative Zero Compromise Optic — Optimized for the Tactical Game
The scope is a Zero Compromise ZC527 (5-27x56mm FFP) with MPCT2 reticle. Zero Compromise Optic is a relatively new manufacturer, but their scopes are top-flight. The First Focal Plane ZCO has excellent glass that is extremely bright and clear. With a big 36mm main tube, the ZC527 offers 35 Mils Elevation and 21 Mils Windage adjustment. The field of view is 21 feet at 100 yards — one of the widest in the industry. The ZC527 also offers illuminated reticle and locking turrets. When I was at my first PRS match I looked through several different scopes. When I got behind a ZCO scope I knew this was what I wanted — the ZCO scope was super clear, super sharp, with very positive controls.
I put a protective wrap on the scope because with some of our PRS stages it is easy to scratch or dent the scope tube. You don’t want to bang up an expensive scope — the ZC527 retails for $3760.
Reloading for 6mm Creedmoor and 6.5 Creedmoor
When starting out with a new cartridge I like to search places like AccurateShooter.com and UltimateReloder.com for popular recipes used by knowledgeable shooters. I am all about paving your own way on certain things but with the consistency, higher cost, and limited supply of components these days I try to stick with the most common loads. I also want to limit barrel wear and get through load development quickly. I don’t want to chase loads for 300 rounds to ultimately land in the same place that so many other people have already found.
I start my new barrels with virgin brass and load three rounds at each charge weight in 0.2 grain increments. I put the most popular charge weight (for my chosen bullet) in the middle of my load range and load above and below to find a good node while paying close attention for pressure signs along the way. I use the 6.5 Guys spreadsheet (see below) to help analyze my results. With those results I like to re-test a narrower range with 5-10 rounds each charge weight in 0.2 grain increments. I again use the 6.5 Guys spreadsheet to make a final charge weight selection and then I move on to seating depth. I will load different depths to tighten the groups up.
Load Development Using 6.5 Guys Custom Spreadsheet
To hold and analyze my load development data I use the spreadsheet from 65Guys.com. It helps a ton with making a decision on your final load. This Excel spreadsheet works great and makes it simple to analyze your data. You can even copy and paste your chronograph data if your chrono logs on to a SD card.
In this 6.5 Guys video Steve provides an overview and tutorial for using the Excel load development analysis model that he has developed. The Excel Load Development Analysis Spreadsheet version 2.0 is FREE. Download from the 6.5 Guys Website.
In this video Steve explains some key statistical concepts for performing load data analysis. He also provides tips and guidance for determining the optimal load for your rifle as you analyze the load data you’ve collected.
New House, New Man Cave/Reloading Room
Jeff recently moved with his family into a great new house. One bonus of this move was that he upgraded from a cramped reloading area to a dedicated “Man Cave” that has ample space for his gun safes, multiple presses, and all his reloading components. Large upper and lower cabinets plus a dedicated “gun closet” provide plenty of storage. Read all about this move in this AccurateShooter Forum Thread.
Here is Jeff’s first reloading area years ago: “My first reloading setup was smashed in my two-bedroom condo so I had a very small bench that was very cluttered. I had to deal with the limited space I had but I made it work. Then in our first house I had a larger bench/cabinet, but it was still not ideal.”
Here is the new Man Cave in the new house — very open, spacious, with plenty of storage.
This animated GIF shows the new Man Cave move-in process start to finish:
As a cartridge case is reloaded multiple times, burnt powder residue and carbon builds up on the inside of the case. Unless the case interior is cleaned in some fashion, eventually you’ll see a slight reduction in case capacity. One of our Forum members from Australia wonders about the effects of reduced case capacity: “If the capacity of the case decreases as the crud builds up, then it effectively reduces the size of the cartridge (inside). Wouldn’t that change the pressure produced from that of an equivalent clean case?”
Interesting Test of Case Capacity Changes
Forum member Fred Bohl has actual test results that can help answer the above question. Fred proved that, over a 20-reload cycle, the case capacity of uncleaned cases did decline a small amount. However, surprisingly, this did not seem to affect the actual chronographed velocity of the load. Extreme Spread (ES) did increase, but Fred believes the higher ES was due to changes in case-neck tension, rather than due to the slight reduction in case capacity. Fred reports:
“Back when beginning to use ultrasonic case cleaning, part of the motivation was to get the inside clean based on the assumption that allowing burnt residue to build up inside cases would affect capacity, and, ultimately, performance. An experiment was done to test this hypothesis. The load used, 30.5 grains of RL15 behind 107gr SMKs in a 6mmBR, was selected for best group and lowest ES in prior load development. It turned out to be 92% of initial case capacity and neither “full” or compressed. (I would suspect that different powders, load weight, and total case capacity might produce very different results.)
We took 30 cases of identical initial capacity and tracked three lots of 10 each:
LOT 1: No Internal cleaning LOT 2: Cleaned with media in tumbler LOT 3: Cleaned with Ultrasound machine
Each case (in each lot) was shot and reloaded 20 times. The simplified results after 20 reloads of each lot were as follows:
Lot 1 (not cleaned) – 0.3 to 0.4 gr. loss of capacity, 5 to 8 fps greater ES.
Lot 2 (tumble cleaned) – 0.1 to 0.3 gr. loss of capacity, 4 to 6 fps greater ES.
Lot 3 (ultrasonic cleaned) – no loss of capacity, no detectable change in ES.
FINDINGS There was no detectable correlation of velocity change to the lots. An oddity was that on very hot days Lot 1 velocities were, occasionally, slightly higher. From results of another ongoing test, I believe the above differences in ES are probably due more to variance in bullet grip tension than case capacity. The ultrasound cleaned cases (LOT 3) did maintain the lowest ES, but we are not 100% sure of the reasons why. More consistent bullet seating might be the reason.”
Editor’s NOTE: Fred’s results do suggest that carbon build-up inside the uncleaned cases might cause a slight increase in pressure that shows up on hot days. Fred has posted that: “A local shooter reported doing the 20 reload, no-clean test on a .308 that gave a loss of capacity of 2.0 grains, doubled ES and significant velocity changes. However, I don’t have any details on his load weight or powder.” Obviously a lot of carbon can build up with 20 reloads. Many shooters retire their brass before then.
Ultrasonic Cleaning and Neck Lube
Some time ago, Jason Baney did a lengthy test on ultrasonic cleaning. Jason found that with his ultrasonically-cleaned cases, the inside of the necks got so “squeaky clean” that he needed to use dry lube in the necks. Jason uses the $21.50 dry lube kit from Neconos.com. This applies ultra-fine Moly powder to the neck interior using small carbon steel balls.
About Jerry Miculek… The Man, The Myth, The Legend
The video above begins: “My name is Jerry Miculek. Guns are what I do.” Jerry Miculek is a true legend in the firearms community. Acknowledged as the best wheelgun speed-shooter in history, Jerry is also an accomplished rifle and shotgun shooter with many class victories in 3-Gun competition. He also has been a prolific YouTube Video creator. For this Saturday at the Movies story, we are featuring five notable Jerry Miculek videos. You will find over 200 more informative and entertaining videos on the Jerry Miculek Pro Shooter YouTube channel
Here Jerry shoots two, double-barrel .45 ACP 1911 pistols (AF2011) at the same time, one in each hand. Jerry was the first-ever person to accomplished this 4-barrel feat with twin handguns. Employing the dual double-barreled pistols, Jerry send 20 rounds downrange in under 1.5 seconds. This amazing sequence is captured with hi-speed cameras for vivid slow-motion playback. There are some spectacular close-ups as the bullets leave the muzzles. Worth watching!
2. Take-Down and Full Cleaning of AR-15
If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. In this video, 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.
3. Jerry Reviews Magnetospeed T1000 Target Impact Indicator
MagnetoSpeed makes more than barrel-mounted chronographs. The T1000 is a target hit indicator that illuminates a super-bright red light when you hit a steel target. The T1000 was designed to be mounted to the back side of AR500 steel targets. In this video Jerry tests the MagnetoSpeed T1000 indicator light system. We like the T1000, especially for longer ranges where impacts on plates may not be easily visible. And you never have to paint your steel targets again to show impacts!
4. Shooting 240 Yards with 85-Year-Old K-22 Rimfire Revolver
Jerry Miculek is probably the greatest (certainly speediest) revolver shooter in history. He has set multiple world records with Smith & Wesson wheelguns. Here he tests a true classic — an 85-year-old S&W model K-22 revolver chambered for the .22 LR rimfire cartridge. Jerry uses this handsome classic blued revolver to hit targets at 240 yards!
5. 80,000 Philippine M1 Garands in One Place
Last year Jerry Miculek recently the CMP where he looked at the vast inventory of military rifles, including 80,000+ M1 Garands recently received from the Philippines. CMP tech staff showed Jerry some rare Garands that had never been issued. If you’re interested in classic military arms, you should definitely watch Jerry’s video. Gina Johnson, CMP’s general manager, told Guns.com that: “We have roughly 86,000 rifles from the Philippines and roughly 13,000 rifles from Turkey in our possession”.
Along with the 80,000+ Philippines Garands, the CMP received 13,000 from Turkey. The arrival of these 99,000 M1 Garands is great news for rifle collectors. Garands have been in short supply in recent years. Garands were getting harder to acquire from the CMP. In fact, over the past two years, many common Garand varients have been “sold out” on the CMP site.

In a follow-up video Mia tests Sako rifles and Sako ammunition at a Finland range. Mia also reported on her Sako factory tour in the Beretta Blog. She notes: “Sako built its original manufacturing facility during World War I. To this day they still utilize the original buildings but have also grown over the years to include larger production areas and updated equipment.”
Canada in the Rough Video Tip from Boyd Allen — we welcome reader submissions
Here’s the good news — loaded ammunition is starting to appear at gun stores again, where shelves were once bare. Here’s the bad news — prices are still WAY higher than they were a couple years ago. High demand and production issues related to the Pandemic continue to create shortages so prices are high. Plus the cost of components, copper in particular is up. That means ammo costs are definitely high. And demand is also driven by new gun owners: “NSSF estimates that 8.4 million people bought a firearm for the first time in 2020. That’s 40 percent of all purchases.” (Source: NSSF.org)

Editor’s NOTE: We generally recommend full-length sizing your cases. But there may be some situations where you may want to body-size your brass in one operation, and then neck-size the case as a final operation for reduced run-out. Or, perhaps you have a non-bushing FL sizing die and you want to modify the neck sizing. This article explains how to use a Lee Collet Die to size case-necks.
For those who prefer to neck-size their brass (rather than full-length-size), the LEE Collet Die is a popular, inexpensive option. It works by having collet tangs or “fingers” press the neck against a central mandrel. A collet squeezes the case neck against a precision mandrel for a perfect fit with minimum run-out. The benefit is that you get a very straight neck, which is sized consistently from top to bottom. Canadian shooter Jerry Teo explains: “LEE Collet Dies produce sized cases with very low runout (measured runout is under .001″ using a Sinclair concentricity gauge). You also don’t get the build-up of brass at the base of the neck, as can happen with bushing neck dies. The neck-shoulder junction stays nice and crisp.”
Here’s a good video that explains how to use a Lee Collet Die to Neck-Size .243 Win brass:
UPDATE to LEE Collet Dies — Neck Protrusion Change
The Lee Precision website notes a small design change: “If you’re a long-time user of Lee Collet Neck Sizing Die you may notice we have modified the Collet so a small portion of the neck protrudes through the end of the Collet-sizing portion. This often-requested modification was implemented in 2019. This change allows the portion of the neck that protrudes above the Collet to remain in its fire-formed condition. This provides a natural flare to the case neck allowing easy and concentric seating of bullets. This is especially important when seating cast bullets or low-drag coated bullets.”
TIP ONE — Adjusting Tension
LEE Collet dies don’t have a specific mechanical adjustment for neck tension. But you CAN easily modify the die to provide more or less tension. If you want to adjust the neck tension using a Lee Collet die, you can simply chuck the mandrel in a drill and reduce the diameter with some sand-paper (to increase neck tension) or you can order a mandrel the next caliber larger and turn it to whatever diameter you want (the larger the mandrel diameter, the less the neck tension). You can also order custom mandrels from Lee sized to any diameter you want.
Regarding neck tension, Boyd Allen makes an important point: “The only way to properly get more neck tension with collet dies is to either reduce the diameter of the mandrel, or order a smaller-diameter mandrel from Lee. I remind folks that adjusting the die position to have more toggle at the top of the ram stroke (not the factory recommended method), or leaning on the press handle with more force than recommended will NOT increase neck tension.”
No Custom Lee Collet Dies For Now
In years past, Lee also offered Custom Collet Dies, made from two fired cases. Hopefully these will be available in the future. However, earlier this year, Lee announced it had suspended sale of most custom dies including Collet Dies: “March 17, 2021: Due to unprecedented order volume, we have suspended custom services for Collet Necksizing Dies, Full-Length Sizing Die Sets, Quick Trim Dies, Case Length Gauges, Factory Crimp Dies, and Bullet Molds until we are able to meet the required volume of our standard products.”
TIP TWO — Polish and Tune for Easy Case Removal
Some users have complained that their Collet Dies grab the case-neck too firmly, making the case hard to remove. There are solutions to this problem. First inspect the collet fingers and smooth the inner surface up a bit with polishing compound or an extra-fine sanding pad. Second, you can open up the fingers a little bit. LEE recommends that if your Collet Die is sticking, take a steel punch and tap the fingers apart a little bit so that the natural “unloaded” position is wider. Lastly, you should lightly lubricate the outside of the collet fingers (see arrows) before you re-assemble the die. This will ensure they slide smoothly. Also, to prevent the collet fingers from closing too tight, never load up the die with your press without putting a case in place first. Without a case neck between the collet fingers and the mandrel, the collet can clamp itself too tight as you raise the ram.
TIP THREE — Always Have a Case Inside When Operating Collet Die
Our friend Boyd Allen tells us that you need to follow directions and NEVER operate the die without a case inside. Boyd explains: “This is because doing so will spring the quadrents of the collet inward so that they interfere with the insertion of a case, and the user will have to figure out how to undo the damage if the die is to operate properly. This advice would not be needed if everyone read the instructions before using the die…. but many times, they don’t. Another thing that I tell new users is to take the die apart so that they will have a better chance of understanding how it works.”
TIP FOUR — Size Twice and Spin Your Case 1/8th Turn
After reaching fully “down” on your press handle, withdraw the case about an inch and manually rotate it about 1/8th (NOT 1/4 or 1/2) turn while still in the shell-holder, then size again. This will place the die’s collet petals on the four “high spots” of the case neck and will result in a rounder, more evenly-sized neck with slightly more bullet tension. This takes only about one second more per case and is well worth the slight extra effort. (We thank reader Stonecreek for this smart tip).

REGISTRATION
Registration is now Open. You can register on-line on the CMP web site and make payment via credit card.
The SAFS courses have been a staple at the annual Camp Perry National Matches since 1918, educating over 1,000 pistol and rifle participants each year. Formulated specially to ease in those of who are new to marksmanship, the school is led by members of the U.S. Army Marksmanship Unit along with qualified civilian and military professionals. The minimum age for Pistol SAFS students is 14 while the minimum age for Rifle SAFS students is 12.
Currently, the CMP offers SAFS courses in smallbore rifle (.22 caliber), rimfire sporter rifle (.22 caliber), centerfire service rifle (M16), and centerfire pistol (M9). Since the schools are intended for beginners, no past firearm experience or gun ownership is required to participate. All ammo will be provided by the CMP along with the M9 pistols and M16 rifles. NOTE: Smallbore students can request to borrow a Walther KK300 for the class — send request to bdonoho@thecmp.org.
SAFS utilizes both classroom and live-fire training that covers basic instruction and firing practices as well as a scope of competition skills. Students in the Pistol (M9) and Rifle (M16) courses will also be entered into a true Excellence-In-Competition (EIC) Match. Though firing in the match is not required, it allows participants the chance to earn four EIC leg points toward a Distinguished Badge.
