Lapua 6mm GT Brass — 100 pcs (4PH6060C)

Match-grade consistency and long service life for modern 6 mm builds
Lapua’s 6mm GT brass delivers the hallmark uniformity and durability competitive shooters expect—stable case capacity, tight dimensional control, and highly repeatable velocities tailored to PRS/NRL and field matches.

Why shooters like it (community feedback)

• Easy to tune, excellent accuracy — users consistently report quick, repeatable nodes in 6 GT.

• Outstanding dimensional uniformity — very even necks/walls and low lot-to-lot variation help drive low ES/SD with minimal prep.

• Mag-friendly geometry — the 6 GT case feeds reliably from AICS-pattern magazines, a clear advantage over shorter 6 mm BR family variants in dynamic stages.

• Slightly lower case capacity vs. some alternatives — many reloaders note you can reach target speeds with a bit less powder, which can simplify tune windows.

• Balanced performance — excellent external ballistics with modest recoil and sensible barrel wear for a hard-running match cartridge.

Technical highlights

• Manufacturer code: 4PH6060C

• Packaging: 100 pieces

• Primer pocket: Small Rifle (SR)

• Flash hole: small, approx. 1.5 mm (0.059")

• Construction: premium brass metallurgy for longevity and repeated reload cycles

Who is it for?

• PRS/NRL competitors who want smooth feeding from magazines with minimal recoil.

• Precision reloaders prioritizing top-tier consistency and straightforward load development.

Practical reloading notes (from user practice)

• Use small-flash-hole decapping pins/FL sizing stems to avoid bending or sticking.

• Many shooters favor keeping speeds around ~2850–2900 fps with 105–110 gr bullets for excellent brass life and stable nodes, rather than pushing “3k+” loads that can accelerate primer-pocket wear.

• As with any match brass, anneal at sensible intervals to maintain neck tension consistency.
