Peli Storm Case IM3300 - Long and Wide Gun Case

When your equipment is too long, too wide, or too valuable for a standard hard case, the Peli Storm iM3300 is the answer. IP67-rated and built from HPX® resin, it handles rifles with scopes still mounted, guitar bodies, precision optics, survey equipment, and anything else that demands extra length and interior width — without compromise on protection or transportability. A retractable telescoping handle and two in-line wheels cover rolling transport; three double-layered soft-grip handles at both ends and the midpoint cover hand carry in any orientation. Certified to MIL-STD-810F, ATA 300, and FED-STD-101C. Available in No Foam or With Foam, in Black or Olive Green. Backed by Peli's unconditional lifetime guarantee.

IP67 Wide-Format Protection

The iM3300 achieves IP67 certification through a full-perimeter O-ring gasket that maintains a continuous watertight seal around its wide-profile lid. Six Press & Pull™ latches close with a positive click and release with a single motion, distributing clamping force evenly across the full lid span. Four padlockable hasps add tamper resistance at multiple points along the perimeter — relevant for airline firearms check-in compliance and freight security alike. Reinforced heavy-duty hinges handle the torque generated by the wide lid, and the HPX® resin shell resists crushing under freight stacking, vehicle compression, and drop impacts. The three handles — at both ends and the midpoint — allow balanced hand carry without tipping regardless of load distribution inside.

What the iM3300 Is Built For

The defining feature of the iM3300 is its width: it accommodates items that standard rifle cases or instrument cases cannot, because the interior is wide enough for equipment with extra bulk at the stock wrist, attached scope rings, a folded bipod alongside the barrel, or a carry handle that adds overall width. Hunters and competitive shooters check it with bolt-action rifles fully scoped for a safari, mountain hunt, or long-range competition stage. Touring musicians use it to fly with guitar or bass bodies when the neck is removed for travel. Survey and geomatics crews transport tripod legs, measurement rods, and long optical instruments. Military and police units choose the Olive Green version for personal weapons and tactical accessories that need a field-compatible case colour.

Three Military and Aviation Certifications

MIL-STD-810F covers shock and vibration resistance across the conditions encountered in military logistics chains — aircraft cargo holds, ground vehicles, and field handling. FED-STD-101C validates packaging integrity under standardised pressure and environmental cycling. ATA 300 is the airline industry's specification for checked freight packaging — a case meeting ATA 300 is accepted as properly packaged under standard airline liability terms, which matters when checking long-format firearms or equipment on a commercial flight. Together, the three certifications make the iM3300 eligible for military supply chains and commercial air freight without modification.

Automatic Pressure Equalization: The Vortex™ Valve

A sealed hard case builds a pressure differential during air transport: at cruising altitude, ambient pressure is lower than the pressure sealed inside at ground level, and the differential reverses on descent. Without compensation, the lid can seal vacuum-tight by the time the case arrives, requiring significant force to open. The patented Vortex™ valve equalizes pressure automatically and continuously — no user action, no valve to open or close. This means the iM3300 opens with normal latch force after a transcontinental flight, a high-altitude mountain drive, or a rapid shift in ambient temperature.

Two Configurations and Two Colors

• No Foam — bare interior shell for customers who supply their own custom foam or plan a CNC-cut insert fitted to their exact equipment profile.
• With Foam — a layered foam set comprising a solid base layer, mid-depth solid layers, and convoluted (eggcrate) lid foam. The lid foam cushions against vibration and minor surface contact on the equipment, while the base and mid layers provide depth and shock absorption for the body of the equipment.

• Black — standard professional colour for transport where a low visual profile matters.
• Olive Green — military field colour for equipment that must blend with tactical and camouflage colour schemes.
