Federal Premium Gold Medal Large Rifle Magnum Match Primers #215M Box of 1000
Clear Product Overview
Federal 215M Primers (Gold Medal Large Rifle Magnum Match) are widely recognized as the gold standard in magnum rifle ignition. Designed for Extreme Long Range (ELR) precision shooters, big-game hunters, and match competitors, these primers are built under Federal’s most stringent quality control standards. Each #215M primer features ultra-tight tolerances for anvil alignment, cup dimensions, and chemical compound weight. Because small variations in flame intensity can cause dramatic vertical stringing at 1,000 yards and beyond, the #215M provides an exceptionally uniform, high-output flame path engineered to minimize Standard Deviations (SD) and Extreme Spreads (ES).

Real-World Use Information
When developing match-grade handloads for ELR competitions, long-range steel matches, or trophy big-game hunts, Federal 215M Primers offer the intense thermal energy needed to cleanly ignite large charges of slow-burning powder. Their precision cup construction seats smoothly in large rifle primer pockets using standard hand-held or bench-mounted priming tools. Furthermore, the match priming mix burns clean and generates consistent flame propagation across sub-zero mountain conditions and hot range environments alike. Consequently, handloaders achieve exceptional shot-to-shot consistency downrange.
Compatibility & Requirements
-
Cartridge Compatibility: Fits all standard large rifle primer pocket magnum brass (.300 Win Mag, .338 Lapua Mag, .300 PRC, 7mm Rem Mag, 28 Nosler).
-
Equipment Compatibility: Seats cleanly with all standard hand priming tools, bench tools, and progressive press priming assemblies (Dillon, Hornady, Lee, RCBS).
-
Safety Requirement: Wear safety glasses during handling, store in a cool, dry location away from heat sources, and never crush primers into dirty or tight pockets.
Pros & Limitations
Pros:
-
Gold Medal Precision: Extremely uniform compound weight tolerances minimize velocity variance at long range.
-
High Thermal Energy: Hot, consistent flame front ensures complete combustion of dense ball and stick magnum propellants.
-
Low SD & ES: Helps achieve single-digit standard deviations in precision long-range handloads.
-
Non-Corrosive Compound: Keeps flash holes and barrel throats free of corrosive damage.
Limitations:
-
Not for Standard Non-Magnum Charges: Using magnum match primers in light, standard rifle charges without adjusting load data can cause unexpected pressure increases.
-
High Demand Availability: Benchrest-quality manufacturing protocols mean supply is frequently limited during peak shooting seasons.
Frequently Asked Questions (FAQs)
Q: What is the difference between Federal #215 and Federal #215M primers?
A: Both primers share identical physical dimensions and flame strength, but the “M” denotes Gold Medal Match grade. #215M primers are manufactured by Federal’s most experienced technicians using tighter tolerances and enhanced quality assurance checks for maximum velocity consistency.
Q: Are Federal 215M primers suitable for .338 Lapua Magnum reloading?
A: Yes, Federal #215M primers are one of the most popular choices among precision handloaders for reloading .338 Lapua Magnum and .300 PRC cartridges.
Q: Can I use Federal 215M primers in standard 6.5 Creedmoor brass?
A: No, standard 6.5 Creedmoor cases use large rifle standard or small rifle primers depending on the brass maker. Federal 215M primers are magnum-class primers and should only be used where large rifle magnum primers are specified in reloading manuals.

Keith –
So far these are the best primers I have used. The combination of bullet, powder, and seating depth are giving less that 1″ group at 200 yards.
