INTERLOCK® 30 CALIBER (0.308′) RIFLE BULLETS – INTERLOCK 30 CALIBER (0.308”) 220GR ROUND NOSE 100/BOX

[cfs_specs_box]

Their traditional line of bullets feature exposed lead tips for controlled expansion and hard-hitting terminal performance. Most have the pioneering secant ogive design — one of the most ballistically efficient profiles ever developed (see diagram to right). Most feature the exclusive InterLock® design — a raised ring inside the jacket that is embedded in the bullet's core that keeps the core and jacket locked together during expansion to retain mass and energy.

Product Features:

INNER GROOVES

Strategically weaken the upper section of the jacket, ensuring consistent, controlled expansion, even at long range.

TAPERED JACKET

Jacket thickness is precisely controlled for expansion at all velocities.

ONE-PIECE CORE

Does not separate like two-piece divided cores. The InterLock® retains more mass and energy for deep penetration and large, consistent wound channels that ensure quick, clean kills.

CANNELURE

Provides accurate and consistent crimping and also works with InterLock® ring to ensure the core and jacket remain locked during expansion.

INTERLOCK® RING

The raised InterLock® ring is embedded in the bullet's core, ensuring the core and jacket are locked in one piece during expansion to retain mass and energy.

Frequently Asked Questions

Are these brass cases and reloading components factory-new or once-fired? +

We stock both premium factory-new components and high-quality once-fired brass. Please check the specific product listing title and description carefully; once-fired brass is fully inspected, but we always recommend resizing and inspecting prior to priming and powder charging.

Will this case trimmer gauge or die set work with my progressive press setup? +

Our standard reloading dies and case length trimmer accessories utilize industry-standard threads (typically 7/8"-14) compatible with major single-stage, turret, and progressive presses like RCBS, Hornady, Lee Precision, and Dillon. Caliber-specific trim gauges must match your exact brass caliber.

Do you enforce shipping restrictions on powder, primers, or live ammunition? +

Yes. Non-hazardous reloading equipment (dies, case length trimmers, gauges, and unprimed brass) ships via standard ground carriers with no extra fees. Any orders containing smokeless powders or primers will incur standard federal HazMat handling fees and cannot be shipped via air transportation.

How can I track my shipment to ensure delivery safety? +

Precision reloading gear is valuable, so all orders are shipped with tracking enabled. As soon as your package is dispatched from our inventory warehouse, a tracking number will be emailed to you. You can monitor your shipment directly on our Track Order page using your unique Order ID.

Can I return precision measuring tools or die components if they don’t fit? +

We accept returns on unused, unaltered tools, case preparation equipment, and unopened component boxes within 30 days of item delivery. Due to safety and strict quality control on the reloading bench, we absolutely cannot accept returns on opened packs of primers, smokeless powder, or processed brass casings.
