Gamo Pellets 4.5 mm (.177): Precision for Air Rifles

What to check before buying Gamo .177 pellets

.177 is the calibre designation commonly shown as 4.5 mm. Calibre alone does not establish compatibility: projectile type, material and dimensions must also match the airgun manufacturer’s specifications.

• Projectile type: check whether your airgun requires diabolo pellets, lead round balls or another specifically approved type of ammunition.
• Pellet weight: compare the weight of the exact product with your airgun manufacturer’s guidance.
• Shape and length: check suitability for the loading port and, where fitted, the magazine.
• Pack quantity: check the number of pellets supplied before comparing prices.

Gamo 4.5 mm pellet models to compare

The following references provide different options within the .177 calibre. Where a product page offers several variants, select 4.5 mm before checking its weight, pack quantity, availability and price.

Head shape alone does not determine which pellet will produce the best groups in your airgun. Weight, dimensions and the individual barrel also matter. Do not assume that similarly named products from different series share the same specifications.

Gamo Match, Hunter or Magnum in .177?

Gamo Match: flat-headed pellets for paper targets

The flat head of Match pellets helps produce clearly defined holes in paper targets. Check that the exact reference is suitable for your air rifle or pistol, including its loading and magazine system.

Gamo Hunter: domed pellets

Hunter pellets have a rounded head rather than the flat profile of Match pellets. Compare the exact product’s weight, dimensions and pack quantity: pellets of the same nominal calibre can perform differently in the same airgun.

Gamo Magnum: pointed pellets

Magnum pellets feature a pointed head. For magazine-fed airguns, check that the pellet’s overall length and shape are compatible with the magazine and feeding mechanism specified by the manufacturer.

Comparing Gamo 4.5 mm pellet weights

The .177 range includes pellets of different weights. A heavier pellet is not automatically more accurate or more suitable for a PCP air rifle. Follow the airgun manufacturer’s guidance and check the specifications of the exact pellet.

Pay attention to the units: grams (g) and grains (gr) are different measurements. Compare weights expressed in the same unit.

You can include the TS-10 when comparing options with Match, Hunter and Magnum, but read the weight stated for the selected version. Do not infer it from the product name or from another calibre.

Gamo AccuTek pellets in 4.5 mm

When comparing established Gamo references with AccuTek versions, check the full product name, geometry, weight and pack quantity. Shared names such as Match or Hunter do not mean that every specification is identical across the two series.

Compatibility with .177 air rifles and air pistols

Gamo pellets may also be suitable for airguns from other manufacturers when they meet the required calibre, projectile type, material and dimensional specifications.

The power source alone does not identify the correct ammunition. Depending on the model, a CO₂ pistol may use diabolo pellets or BBs. Likewise, a PCP air rifle is not automatically compatible with every 4.5 mm projectile.

For rotary magazines, check pellet length and head shape as well as calibre. If a pellet does not fit correctly, do not force the magazine closed or force the feeding mechanism.

Comparing prices and pack quantities

Two tins with similar prices may contain different numbers of pellets. Compare the quantity supplied alongside the model and pellet weight.

To calculate the cost per 100 pellets, divide the pack price by the number of pellets and multiply by 100. Make sure the 4.5 mm variant is selected before comparing prices.

Store pellets in their closed container in a dry place, protected from knocks. Do not use damaged or dirty pellets.
