Remington Ultimate Defense .410 Bore 2.5 Inch 000-Buck 4 Pellet – 15 Rounds (Box) 410B000HD

Remington Ultimate Defense .410 bore shotshells turn a .410 shotgun or a .410 capable revolver into a serious personal protection tool, and this box holds 15 rounds of it. Each 2.5 inch shell carries four pellets of 000 buckshot leaving the muzzle at 1225 feet per second, model 410B000HD. That is a purpose built defensive payload rather than a repurposed field load, and the difference shows the first time you pattern it.

What the Remington Ultimate Defense .410 load is built to do

Defensive ammunition has one job, and it has to do that job on the worst night of your life. This shell is built around reliability first, then power, then pattern consistency.

Four pellets of 000 buck is a heavy per pellet payload for the smallest standard shotgun bore. Each of those pellets is large enough to penetrate meaningfully, which is exactly what a defensive load must do at across the room distances.

It is aimed at homeowners running a .410 home defense shotgun, at owners of compact .410 revolvers, and at anyone who wants a soft shooting defensive platform that a smaller framed or recoil sensitive shooter can actually control under pressure.

How these shells are put together

The engineering here is not marketing filler. Each element addresses a specific failure point that defensive ammunition simply cannot afford.

• High brass construction that supports reliable ignition and consistent cycling
• High quality lead pellets that hold their shape and produce tight, repeatable patterns
• Deep penetration from four large 000 buckshot pellets rather than a cloud of small shot
• A specially formulated propellant that keeps velocity consistent from shell to shell
• A 2.5 inch hull that chambers in both dedicated shotguns and .410 capable revolvers
• Fifteen rounds per box, enough to pattern the gun and still keep it loaded

Reading the numbers

The gauge is .410 bore and the shell length is 2.5 inches, which matters because plenty of .410 firearms, including many revolvers, are chambered for 2.5 inch shells only. Always confirm your chamber length before loading longer hulls.

The shot is 000 buckshot with a pellet count of four, and muzzle velocity is listed at 1225 feet per second. There are 15 rounds per box, and the manufacturer model number is 410B000HD.

Remington has been building ammunition in the United States for longer than most firearms companies have existed, and the Ultimate Defense line is where that manufacturing experience gets pointed squarely at protection loads.

Patterning, storage, and practical use of the Remington Ultimate Defense .410

Pattern before you trust it. Set a target at the realistic distance you would actually face inside your home, usually seven to ten yards or considerably less, and see where those four pellets land out of your specific barrel or cylinder.

Barrel length and choke change everything with a .410. A short revolver barrel will open a defensive load far more quickly than a full length shotgun barrel, so test rather than assume.

Store the box somewhere cool and dry. Shotshells are tough, but heat cycling and humidity are the two things that shorten their life, and defensive ammunition deserves better than a hot glovebox.

Rotate your loaded rounds occasionally, and keep cleaning supplies and storage on hand from our Apparel and Gear collection so the gun holding this ammunition stays as reliable as the ammunition itself.

Keep a second box for training. Shooting the Remington Ultimate Defense .410 in practice, rather than only loading it and hoping, is how you learn what the recoil feels like from a light revolver and how quickly you can get back on target for a follow up shot. Defensive skill is built with the exact ammunition you carry, not with the cheapest thing on the shelf.

The .410 has quietly become a genuinely popular defensive chambering, and loads like this are the reason why. With 15 rounds in the box you have enough to pattern your gun, run a practice string, and still put it away loaded with the exact ammunition you tested. Ships direct to your door, no FFL required.
