Heavyweight Precision for Distance

The Bisley Magnum .177 is a heavy 10.65gr domed pellet built for shooters who want reach and consistency. That extra mass carries momentum downrange, so the pellet holds its line and shrugs off crosswind far better than a lightweight round, making it a sound choice for ranges out to around 50 yards and beyond.

Made for Serious Shooting

Field target, hunting and long range work all reward a pellet that groups tightly, and the Magnum delivers with a precise domed profile. A special alloy and greasing help cut lead fouling and keep groups uniform tin after tin.

Matched to Your Rifle

Suited to high power spring, CO2 and PCP air rifles in both 12ftlb and FAC forms, the Magnum is offered in 4.50mm, 4.51mm and 4.52mm head sizes so you can tune the fit to your barrel. Each tin holds 500 pellets.

Frequently asked questions

Do I have to be 18 to buy these?

Yes. You must be over 18 to purchase airgun ammunition. Proof of ID is required for both in-store and online orders, and pellets will not be shipped without prior confirmation of ID.

What are these pellets best for?

At a heavy 10.65gr they are built for field target, hunting and long range shooting, holding their line well and shrugging off crosswind at ranges out to around 50 yards and beyond.

Which head size should I choose?

Bisley Magnum comes in 4.50mm, 4.51mm and 4.52mm head sizes. Slightly larger heads can improve grip in some barrels, so it is worth testing a couple to see which your rifle prefers.

What air rifles are they suited to?

They are designed for high power spring, CO2 and PCP rifles, including both 12ftlb and FAC rated guns, where the extra weight makes the most of the available energy.

Why is a heavier pellet better at distance?

A heavier pellet carries more momentum downrange, so it resists wind drift and holds its trajectory better than a light pellet, giving more consistent groups at long range.
