We bring science to precision shooting
Walk any rifle range and you will hear the same debates: which powder, which bullet, which seating depth. What you will not hear is how anyone could actually know. A five-shot group is a small sample, and two loads can trade places on any given day for no reason but chance. Shooters burn barrels and brass chasing differences that were never real, and walk away from loads that were genuinely good.
We built DimeShooters because we wanted better answers for ourselves. Photograph a target and the platform corrects for camera angle, finds the bullet holes, and measures the group more precisely than calipers. Behind that sits real statistics: confidence intervals, significance tests, and a load development planner that tells you how many shots it actually takes to know something. And because every shooter's anonymized dispersion results join a shared community pool, you can see what works in rifles like yours before you ever seat a bullet.
The question we set out to answer is the one every serious shooter eventually asks: was that group skill, or was it luck? Now there is a way to find out.
To help precision shooters tell real performance from luck, through rigorous statistics, honest measurement, efficient experimental design, and shared community data.
A sport where evidence replaces anecdote. We envision serious shooters everywhere planning their experiments, recording their results, and learning from the community's data rather than its folklore. The paper logbook and the spreadsheet served their time; we are building what comes next.
Five things we hold ourselves to, in everything we ship.
We say what the data supports and nothing more. When a result is inconclusive, we tell you it is inconclusive. No inflated claims, no manufactured proof, no numbers we cannot stand behind.
Every statistic on the platform rests on sound methods: bias-corrected estimates, confidence intervals, significance testing. We publish the mathematics behind our analysis so you can check our work. Uncertainty is reported, never hidden.
We would rather do a few things exceptionally well than many things adequately. Careful measurement, tested code, honest documentation: the same discipline a handloader brings to the bench.
Shooters improve faster when they learn from each other's data instead of each other's anecdotes. Every subscriber's anonymized dispersion statistics strengthen a pool that benefits everyone, and knowledge compounds when it is shared.
We built DimeShooters for ourselves, and we treat you the way we want to be treated. Your images, your identity, your serial numbers, and what you paid for your equipment are never shared. Pricing is plain, and you do not need a statistics degree to benefit from the analysis; the math works for you, not the other way around.
Two founders, 25 years of friendship, one standard.
Co-founder and president
James grew up in the mountains of Northern California, where he learned to hunt deer as a boy. He has hunted his whole life and competes in precision rifle matches today. Professionally, he is a professor of electrical and computer engineering at Portland State University with a career in signal processing, statistics, and computer vision, and he co-founded APDM, a medical technology company. DimeShooters is where three of his lifelong pursuits finally meet: shooting, statistics, and algorithms.
Co-founder and CTO
Markus is a software engineer with decades of experience building web platforms, cloud infrastructure, and the systems that keep them reliable. He and James have been friends for more than 25 years. Markus came to precision shooting recently, firing his first PRS match in the summer of 2026, and that newcomer's eye is built into the product: if a feature is not clear to a shooter still learning the sport, it is not finished. Every screen has to earn its place with both the veteran handloader and the shooter uploading their first target.
A group of shots small enough to hide under a dime is shorthand for real precision. The dime is also a ten, and ten is what the center of a target pays. The name honors both: the size reference and the perfect score. It is the standard we hold our own shooting to, and the standard we hold this platform to.
DimeShooters is an Oregon company James and Markus founded in 2024. We are independent and self-funded, which means we answer to shooters rather than investors. We use the platform every week ourselves; our own targets and load data were the first records in the database.
