Federal Premium Power-Shok .303 British 180gr JSP — 500 Rounds

The Federal Power-Shok 303 British is the hunting load in the .303 British category.

A 180-grain JSP at 2,460 fps and 2,418 ft-lbs — Federal’s traditional lead-core hunting bullet in the heavier of the two common .303 British hunting weights.

At $1.03 per round for 500 rounds, this is Federal’s value hunting tier for the .303 British.

The same Power-Shok construction available in dozens of popular calibers — applied to a cartridge most US manufacturers produce only in limited runs.

Power-Shok — Federal’s Traditional Value Hunting Line

Power-Shok is Federal’s traditional lead-core JSP line, positioned below the premium Fusion and Terminal Ascent loads in price while retaining Federal brass, primers, and powder. Three characteristics define it:

Jacketed Soft Point construction. The exposed lead tip at the nose initiates expansion on impact. The copper jacket controls the expansion rate, preventing the bullet from disintegrating while allowing the front section to mushroom predictably.

Federal components throughout. The Federal Power-Shok 303 British uses Federal brass, Federal primers, and Federal-spec powder — not sourced externally. Consistent ignition and chamber pressure across a 500-round production run matters for accuracy.

Broad game applicability. At 2,418 ft-lbs, the 180-grain load carries sufficient energy for deer and black bear at the distances a Lee-Enfield is typically used for hunting — inside 250 yards.

180 Grains — The Heavy .303 British Hunting Weight

The .303 British is most commonly loaded at 150 and 180 grains for hunting.

The 150-grain loads in Related Products produce higher velocity but less sectional density. The Federal Power-Shok 303 British 180-grain trades some velocity for a heavier, higher-SD bullet — better retained energy and deeper penetration into larger game.

For deer-sized game inside 200 yards, either weight works. For black bear or medium-heavy game where deeper penetration matters, the Federal Power-Shok 303 British 180-grain is the correct choice.

💬 Before You Go — Hunting With .303 British?

Using Power-Shok 180gr JSP for deer or bear from a Lee-Enfield or other .303 British rifle? Leave a review with the rifle and game taken — shot distance and species data from .303 British hunters is sparse and genuinely useful to other Lee-Enfield owners making load decisions. And if you came looking for a .303 British load we don’t carry, tell us. 🎯

Frequently Asked Questions

What is the Power-Shok line and how does it compare to Federal’s premium hunting loads? Power-Shok is Federal’s traditional value hunting tier — conventional jacketed soft point bullets with a lead core, using Federal brass, primers, and powder. It sits below the bonded Fusion and the premium Trophy Bonded Bear Claw / Terminal Ascent lines in price and construction sophistication. For most deer hunting at .303 British distances (inside 200 yards), Power-Shok JSP performs reliably. For bone-heavy hits or larger game, a bonded bullet retains more weight.

Why choose the 180-grain over the 150-grain loads in the category? Sectional density. The 180-grain bullet is heavier relative to its diameter, giving it higher SD and better penetration into large game. The 150-grain loads produce higher velocity but carry less mass for deep penetration. For deer at close range either works; for black bear or elk-class game where reaching the vitals requires penetrating through heavy shoulder muscle and bone, the 180-grain is the better choice.

Is this appropriate for all .303 British rifles, including military surplus Lee-Enfields? Yes — commercial SAAMI-spec .303 British is safe in military surplus Lee-Enfields. Non-corrosive Boxer-primed brass is significantly preferable to military surplus Berdan-primed corrosive ammunition in these rifles, which require prompt cleaning after shooting corrosive loads. Federal Power-Shok eliminates that cleaning urgency.

What is the JSP design and how does it expand? The exposed lead nose initiates expansion when it contacts the target. The copper jacket controls the rate and extent of expansion, preventing the bullet from disintegrating while allowing the front section to mushroom. Traditional JSP design — well-established performance on medium and large game across hundreds of calibers.

Is the brass reloadable? Yes — Federal brass, Boxer primer.

How many rounds is 500? 25 × 20-round boxes.

What’s the per-round cost? $514 / 500 = $1.028 per round.

What is the Federal SKU? 303AS — visible in the product image filename.
