Projectile construction

This is a a target design chosen for consistency rather than terminal effect. The hollow point is a manufacturing artefact of the jacket drawing process, not an expansion mechanism, so it should not be selected as a hunting bullet.

Bullet weight and bullet construction get conflated constantly. Weight sets trajectory and momentum; construction sets what happens on impact.

6.5 Creedmoor background

High ballistic coefficient bullets hold velocity downrange, which is why it displaced .308 for competition.

Muzzle velocity for 6.5 Creedmoor typically runs 2,700 to 3,000 fps, from a AR-10 or bolt platform with a 1:8 twist. Expect real world variation against those figures. A chronograph and ten rounds will tell you more than any spec sheet.

Choosing this bullet weight

At 142 grain this is on the lighter side for 6.5 Creedmoor. Lighter bullets leave the muzzle faster and shoot flatter, which helps on smaller targets and at distance, but they bleed velocity sooner and depend more on impact speed to do their job.

Pack size and cost per round

20 rounds at $55.99 works out at $2.800 per round. A box this size suits load development, hunting stock and defensive carry rather than high volume practice.

Before you order

Shipping rules for ammunition vary by state and sometimes by city. Some destinations require a licence, an approved recipient, or refuse delivery entirely. Check before you order rather than after. See our shipping and delivery page for the current detail.

Who this load suits

Match the load to the job rather than the price. This is a target and load development projectile. It is not a hunting bullet, and choosing it for game is the single most common mistake with this bullet line.

Barrel length matters

Velocity scales with barrel length, and the effect is largest on lighter, faster bullets. Check what your own barrel actually delivers. For 6.5 Creedmoor specifically, expect 2,700 to 3,000 fps as the published band and treat your own chronograph as the authority.

Keeping it serviceable

Store it dry and cool, rotate oldest stock first, and check case necks for corrosion on anything that has sat a long time.

6.5 Creedmoor against the alternatives

Against .308 Winchester it wins on wind drift and retained velocity while giving up frontal area and some bullet choice. Against .260 Remington the difference is mostly brass availability rather than ballistics.

Pick the cartridge that fits the shooting you actually do, not the shooting you read about.

How this is stored

What ships is sealed factory ammunition, stored indoors and rotated so the oldest stock moves first. Packing is chosen to stop cartridges moving inside the box.

Frequently asked questions

Which twist rate does 6.5 Creedmoor need?

1:8 is standard. High ballistic coefficient bullets hold velocity downrange, which is why it displaced .308 for competition.

How fast does 6.5 Creedmoor run?

Around 2,700 to 3,000 fps at the muzzle, though your barrel will give you its own number.

Is the match hollow point boat tail projectile suitable for what I am shooting?

It is a a target design chosen for consistency rather than terminal effect. The hollow point is a manufacturing artefact of the jacket drawing process, not an expansion mechanism, so it should not be selected as a hunting bullet. Match that against your intended use before buying.

Why choose 142 grain?

Weight sets the trade between velocity and momentum. 142 grain is one point on that curve; the right pick depends on your barrel, your distance and your target rather than on the number itself.

What is in the pack?

20 rounds at $55.99, which is $2.800 per round.
