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.

.308 Winchester in practice

The reference cartridge for .30 calibre performance, with the widest bullet selection of any rifle round.

Muzzle velocity for .308 Winchester typically runs 2,400 to 2,800 fps, from a AR-10 or bolt platform with a 1:10 to 1:12 twist. Expect real world variation against those figures. A chronograph and ten rounds will tell you more than any spec sheet.

Where this weight sits

At 168 grain this is on the lighter side for .308 Winchester. 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.

Cost per round

20 rounds at $49.99 works out at $2.500 per round. A box this size suits load development, hunting stock and defensive carry rather than high volume practice.

Shipping and legal notes

Ammunition is not a firearm under federal law, but shipping is restricted in a number of states and municipalities, and some require a licence or an approved recipient. Buyers must be of legal age and legally permitted to possess ammunition where they live. See our shipping and delivery page for the current detail.

Who should buy this

Loads are tools, not rankings. 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.

What your barrel does to these numbers

Barrel length changes the numbers. Short barrels give up velocity that light bullets in particular depend on, so a load that performs from 20 inches may disappoint from 16. For .308 Winchester specifically, expect 2,400 to 2,800 fps as the published band and treat your own chronograph as the authority.

Storage notes

Ammunition stores for decades if you keep moisture and temperature swings away from it. Sealed containers with a desiccant pack beat an open box in a shed every time.

How .308 Winchester compares

Against 6.5 Creedmoor it gives up ballistic coefficient and wind performance, and gains bullet selection, brass availability and lower cost. Against .30-06 it gives up a little case capacity in a shorter action.

There is no universally correct answer here, only a correct answer for a given rifle, distance and target.

What we ship

Every load leaving here is factory ammunition from the manufacturer, not repackaged or remanufactured stock. Lots are stored indoors at stable temperature and packed so bullet tips are not knocking against each other in transit.

A word if you are stocking up: test before you commit. Buying a case of a load your rifle dislikes is an expensive way to learn about harmonics.

Frequently asked questions

Which twist rate does .308 Winchester need?

1:10 to 1:12 is standard. The reference cartridge for .30 calibre performance, with the widest bullet selection of any rifle round.

What velocity should I expect from .308 Winchester?

Typically 2,400 to 2,800 fps. Barrel length, temperature and lot all shift it, so chronograph your own rifle.

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 168 grain?

Weight sets the trade between velocity and momentum. 168 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 $49.99, which is $2.500 per round.

Is this load in stock?

Yes. Everything on this page is held in stock and ships from the United States. Sold out lines are updated rather than left live.

Can you ship this to my state?

In most cases yes, though several states and cities restrict ammunition shipments or require a licence. Our shipping page lists current restrictions.

How should I compare loads?

Compare cost per round rather than box price, and compare projectile construction rather than grain weight. Those two habits will steer you right more often than brand loyalty.

Do you offer bulk pricing?

Larger pack sizes carry a lower cost per round, which is listed on each product page so you can compare directly rather than doing the arithmetic yourself.

Will this arrive in original packaging?

Yes, in the manufacturer’s packaging, boxed so nothing shifts on the way to you.
