Your competition ammo can make or break a Nationals match. You’ve put in the time, the training budget, and the travel to get there. Many shooters had to qualify just to earn a spot on the line.
That is not the place for questionable ammunition.
Shell Shock Technologies sponsored shooter John Vlieger knows the stakes. This season he placed 6th at Factory Gun Nationals and took 7th in Open Division at the US IPSC Nationals. Here’s how he builds and tests his match ammunition for top-tier events.
Most shooters train with ammo that’s good enough for 95% of their shooting. Cost and availability drive that choice, and that’s fine for practice.
Nationals is different. “You never want to bring ammo that’s questionable or a gun that’s questionable to Nationals,” John says. “You want to bring your best.”
Think about what it takes to get there: months of training, travel, entry fees and, for most shooters, a qualifying run. Your match ammo should be the one variable you never have to think about.
Any component with an unknown history adds doubt. A previously fired case might have a dinged rim or an unknown number of firings behind it. One bad round can mean a stoppage on the clock, and even when it never happens, the question sits in the back of your mind.
That’s why serious competitors keep their proven recipe and build their competition ammo on new components, starting with the case. For Nationals, John loads the same recipe he trains with into brand-new NAS3 cases.
Nationals’ stages reward accuracy at distance. At the match John just shot, one paper target offered a 42-yard option.
“I had alpha-charlie on that hit, and I knew it when I fired it,” he says. “I know my hold, I know my gun is accurate, and I know my ammunition is accurate.”
That confidence only comes from testing. A coated bullet that groups three inches at 20 yards might be fine for practice. A premium jacketed hollow point could tighten that group considerably.
Have you tested it? Bench your gun and shoot your competition ammo at the distances you’ll see on stage. Some combinations work with anything you throw at them, but you won’t know until you check.
If you don’t load your own, Shell Tech 9mm Nosler ASP loaded ammunition pairs a premium jacketed hollow point with NAS³ case technology. It’s worth putting on paper alongside your current load.
When John optimizes his ammo for Nationals, brand-new NAS³ cases are his top choice. It removes the unknowns that come with previously fired cases.
New cases give you a consistent headstamp, rim thickness, and rim diameter. There are no dings or divots from a previous trip through an extractor.
“If it runs with this headstamp, it should continue to run with this headstamp,” John says, “because the variables in this component are minimized.”
That holds whether you’re running a custom race gun or an off-the-shelf production pistol. Consistent components make your testing results more trustworthy.
NAS³ cases add more. They are made from a nickel-stainless steel alloy and engineered with increased internal volume. That design allows more efficient use of powder energy, so shooters can achieve higher velocities at standard SAAMI pressures compared to traditional brass.
They’re also lighter than brass, gentler on extractors, and designed for smooth ejection. In John’s experience, they eject cleanly and consistently. Learn more about how NAS³ case technology works, or pick up Shell Tech 9mm NAS³ unprimed cases for your match loads.
Before Nationals, double- and triple-check that your competition ammo meets your division’s requirements. In USPSA, that means power factor.
The formula is simple: bullet weight (grains) × velocity (fps) ÷ 1,000.
A 124-grain bullet at 1,000 fps makes a power factor of 124. That falls short of the 125 minimum for minor. Fall below it at the chronograph, and your score takes a serious hit.
Most competitors build in a cushion and load to a 130–135 power factor. John’s Nationals ammo came in at 134–135. He loads a 124-grain jacketed hollow point to roughly 1,080 fps, just over the sound barrier.
Velocity consistency matters here too. John sees more consistent velocities with NAS³ cases, which gives him confidence his ammo will make power factor every time it’s tested.
Always develop loads from published load data and stay within SAAMI pressure specifications. Check the current USPSA rules for your division’s power factor requirements before match day.
When John shoots Open Division, his practice and match loads use the same powder charge, the same primer, and the same projectile.
He runs jacketed hollow points in both. Their enclosed base keeps hot gas off exposed lead, which cuts down on lead buildup in his compensator. Otherwise, he’d be cleaning it out roughly every 5,000 rounds.
The one component he changes for the match is the case. He moves to NAS³ for consistency. “I want it all to be the same,” he says. And if he’s flying to the match, the lighter NAS³ cases help with weight.
For minor-division shooting, John may practice with brass or FMJ loads and switch components for the match. When you do that, re-test before match day. Any component change is a new load, and it deserves its own chronograph and accuracy check.
For high-volume practice, Shell Tech 9mm FMJ ammunition keeps you training with NAS³ case technology from the first round.
Optimizing your competition ammo for Nationals comes down to one principle: test, evaluate, and decide.
Confirm your velocity. Confirm your accuracy at distance. Minimize the variables in every component, starting with the case.
“The core of it is I need to test these things,” John says. Do the work before you travel, and you’ll show up with ammunition you can trust on every stage.
