Terminal behaviour of the solid copper fragmenting design

This is a sheds petals into separate wound paths on impact while the base continues forward, giving multiple channels plus penetration from a single projectile.

It is worth separating weight from construction when comparing loads. They are independent variables, and construction is the one that decides outcome.

.308 Winchester background

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 175 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 $44.99 works out at $2.250 per round. A box this size suits load development, hunting stock and defensive carry rather than high volume practice.

Ordering and compliance

Ammunition ships within the United States subject to state and municipal restriction. Some jurisdictions require licensing or prohibit delivery outright, and buyers must meet age and eligibility requirements where they live. See our shipping and delivery page for the current detail.

What your barrel does to these numbers

The same load behaves differently across barrel lengths. If you run a short barrel, verify performance rather than assuming it carries over. For .308 Winchester specifically, expect 2,400 to 2,800 fps as the published band and treat your own chronograph as the authority.

.308 Winchester against the alternatives

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.

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

Stock and handling

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.

If this is your first purchase in this calibre, buy one box before you buy ten. Rifles are individual, and a load that groups beautifully in one barrel can string in another for no obvious reason.
