Meridian Ammunition · Loaded in Ridgeline, Missouri since 1968
It begins as a coil of C26000 cartridge brass, cupped on presses we built ourselves.
Drawn in-house since 1968
Four draws and a stress-relieving anneal bring every case wall into print.
±0.0005 in case wall tolerance
Each lot is fired, measured, and signed off before it ever earns a headstamp.
Every lot pressure-tested
Four components. One argument, settled the same way every time. Follow the section drawing - each part lights as its story passes.
01
A match-grade Boxer primer, seated to a measured two-thousandths crush - never flush-and-hope. One primer lot runs from the first round of a production run to the last.
| SEAT DEPTH | −0.002 / −0.004 IN |
| CUP | MATCH, SINGLE LOT |
| SENSITIVITY | 100% AT 12 IN·OZ |
02
Temperature-stable extruded powder, thrown then trickled to weight on every station. When the thermometer swings ninety degrees between the truck and the blind, the load doesn't.
| CHARGE | 41.6 GR ±0.02 |
| TEMP SHIFT | <0.2 FPS / °F |
| FILL RATIO | 94% CASE CAPACITY |
03
A 140-grain open-tip match bullet with a boat tail drawn concentric to fifteen ten-thousandths. The jacket is swaged in the building next door; we check runout on every tray, not every lot.
| WEIGHT | 140 GR ±0.1 |
| BC | G1 .610 · G7 .313 |
| RUNOUT | ≤0.0015 IN TIR |
04
No roll crimp to crush a match bullet - just uniform neck tension, verified by a force curve on every seating stroke. The press rejects the round, so the target never has to.
| NECK TENSION | 0.002 IN |
| SEATING FORCE | 38-46 LBF WINDOW |
| COAL | 2.800 IN ±0.003 |

Every match lot fires a ten-shot group from a rail gun at a hundred yards. The target is filed with the lot record.

Conformal transducers on a SAAMI-spec barrel. Peak pressure, rise time, and port timing on record for every lot.

THE STANDARD
If a lot won't hold a minute from a rail gun, it doesn't become Meridian Match. It becomes a lesson - and it never leaves the building.
"You spend eleven months planning for one cold morning. The round is the last thing I want to be thinking about up there - so it's the one thing I never do."
