How to choose air rifle pellet weight and shape

How to Choose Air Rifle Pellets: Weight & Shape (2026)

Pellet shape decides how a pellet flies once it leaves the barrel, and pellet weight decides how much energy it carries when it gets there — for most Irish air rifle shooters in 2026, a mid-weight domed pellet in the calibre that matches the rifle's power band is the safest default, with flat-head or hollow-point options reserved for specific jobs like paper targets or close-range pest work. The wrong combination doesn't just cost accuracy — a pellet too light for a high-powered PCP burns energy on wind drift, and one too heavy for a low-powered springer can shoot behind the point of aim at any distance past 20 metres.

TL;DR
  • Domed (diabolo) pellets are the accurate all-rounder for hunting and general use in 2026.
  • Flat-head (wadcutter) pellets punch cleaner holes for paper targets but drop faster past 25 metres.
  • .177 rifles typically run 7-8 grain domed pellets; .22 rifles typically run 14-16 grain domed pellets.
  • Heavier pellets resist wind drift better; lighter pellets shoot flatter but scatter more in a crosswind.
  • Weight consistency within a tin matters more for accuracy than the number printed on the box.

Why this matters

Get pellet choice wrong and the rifle takes the blame for what's actually a pellet problem. A rifle that groups tight with one pellet can throw fliers with another simply because the shape or weight doesn't suit its power output or barrel twist. Choosing air rifle pellets correctly in 2026 means matching three things: the calibre stamped on the barrel, the power output of the rifle (spring-piston or PCP), and the job — target work, rabbiting, or pest control on a farm.

How to choose air rifle pellets: shape comparison

Four shapes cover almost every pellet on the Irish market. Each behaves differently in flight, and the differences show up most past 20-25 metres.

Shape Best for Ballistic coefficient Trade-off
Domed (diabolo) General hunting, pest control, all-round use Good None major — the standard choice for good reason
Flat-head (wadcutter) Paper targets, close-range plinking Poor Drops fast and drifts more past 25m
Pointed Penetration-focused pest work Moderate Less consistent grouping at range than domed
Hollow point Small game, close-range pest control Poor to moderate Expansion drops retained energy at distance

Domed pellets win for most Irish shooters — they hold velocity better than flat or hollow-point designs and group more consistently past 30 metres, which covers most rabbiting and vermin control ranges. Buy domed as the default.

Domed pellets: the all-round choice

Domed, or diabolo, pellets have a rounded nose and a waisted body that stabilises them in flight. They carry a better ballistic coefficient than flat or hollow-point shapes of the same weight, which means less velocity loss and less wind drift over 25-40 metres. For anyone using an air rifle for rabbiting or farm pest control in Ireland, domed is the shape to buy first — check the air rifle calibres for rabbiting guide if you haven't settled on a calibre yet. Verdict: Buy as the default pellet shape for hunting, pest control, and general shooting.

Flat-head pellets: built for paper, not range

Flat-head (wadcutter) pellets cut a clean, round hole in card or paper, which is why target shooters at indoor and short-range outdoor ranges favour them. The flat nose kills the ballistic coefficient compared to a domed pellet of the same weight, so velocity bleeds off faster and wind drift increases noticeably past 25 metres. Verdict: Buy for paper target work at fixed short range; Skip for hunting or anything past 25 metres.

Pointed pellets: penetration over precision

Pointed pellets were designed on the assumption that a sharper nose penetrates better, which holds true on soft tissue at close range but doesn't translate into tighter groups. Most pointed pellets group looser than domed pellets from the same rifle because the pointed nose is less stable in flight. Verdict: Hold — only worth testing if a specific rifle happens to shoot them well, which isn't common.

Hollow point pellets: close-range stopping power

Hollow points expand on impact, which increases stopping power on rabbits and similar-sized pest species at close range. The trade-off is the same as flat-heads: a lower ballistic coefficient means faster velocity loss and more drop past 25-30 metres. Farmers running foxes or rabbits at close range under structures or in outbuildings sometimes prefer hollow points for exactly this reason — see the air rifles for pest control guide for rifle and pellet pairings used on Irish farms. Verdict: Buy for close-range pest work under roughly 25 metres; Wait if most shots happen past that range.

Why pellet weight varies by calibre and rifle

Pellet weight is measured in grains, and the right weight depends on more than just calibre stamped on the barrel:

  • Calibre — .177 (4.5mm) pellets typically run lighter, commonly 7-8 grains in a domed profile; .22 (5.5mm) domed pellets typically sit around 14-16 grains.
  • Rifle power output — a low-powered spring-piston rifle struggles to push a heavy pellet to a useful velocity, while a full-power PCP can handle heavier pellets without losing much trajectory.
  • Barrel twist rate — faster twist rates stabilise heavier pellets better; a barrel cut for lighter pellets can under-stabilise a heavy one and open up groups.
  • Wind conditions — heavier pellets resist crosswind drift better than light ones travelling at the same or higher velocity.
  • Shooting distance — light pellets shoot flatter out to 20-25 metres; heavier pellets hold energy and resist drift better past that.
  • Job — target shooting favours lighter, faster pellets for a flatter trajectory; hunting and pest control favour retained energy over raw speed.

If you're running a PCP rifle and haven't matched pellet weight to the regulator's power curve, the PCP air rifles for pest control guide covers typical power bands by calibre for 2026-spec rifles.

Is a heavier pellet always more accurate?

No — a heavier pellet is not automatically more accurate; accuracy depends on matching pellet weight to the rifle's power and barrel twist rate. A rifle tuned for a 7-8 grain .177 pellet can open up its groups if pushed to a much heavier pellet the barrel wasn't built to stabilise.

What weight pellet should I use in a .177 air rifle?

A .177 air rifle typically runs a 7-8 grain domed pellet as the balanced choice between velocity and retained energy. Lighter pellets in the 4.5-6 grain range shoot flatter for target work but lose energy fast past 25 metres, while heavier .177 pellets up to around 10.5 grains suit higher-power rifles chasing more retained energy downrange.

What weight pellet should I use in a .22 air rifle?

A .22 air rifle typically runs a 14-16 grain domed pellet, which is the standard weight for hunting and pest control at moderate range. Heavier .22 pellets, up to around 18-21 grains, suit full-power PCPs where retained energy at 30-40 metres matters more than a flat trajectory.

Do pellet-to-pellet weight variations within a tin matter?

Yes — weight consistency within a tin affects accuracy more than the headline weight printed on the box, because even small variations between individual pellets change how each one flies at range. Premium match-grade tins sort pellets by head size and weight for exactly this reason, which is why they cost more but group tighter.

One last thing

Most shooters chase muzzle velocity numbers and ignore the one variable that actually predicts group size: consistency between pellets in the same tin. Two tins can list the identical weight on the label and shoot completely differently from the same rifle, because head diameter and weight tolerance vary between batches. Before switching calibre or shape to chase accuracy, run a proper group test with two or three tins of the same weight from different batches — it's the cheapest diagnostic available in 2026 and it settles more accuracy arguments than any spec sheet.

FAQ

What's the best pellet shape for hunting with an air rifle?

Domed (diabolo) pellets are the best shape for hunting because they hold velocity and group tighter past 25 metres than flat-head or pointed shapes. Hollow points are a reasonable alternative for close-range pest work under 25 metres.

Is a domed pellet better than a pointed pellet?

Yes, domed pellets are generally more accurate than pointed pellets because the domed shape stabilises better in flight from most air rifle barrels. Pointed pellets offer a penetration theory that rarely translates into tighter groups.

How much does pellet weight affect FPS?

Lighter pellets leave the barrel at higher FPS than heavier pellets from the same rifle, because the same amount of stored air or spring energy accelerates less mass faster. The trade-off is that lighter pellets lose velocity and drift in wind faster than heavier ones over distance.

What weight pellet is best for a .177 air rifle?

A 7-8 grain domed pellet is the standard weight for a .177 air rifle, balancing flat trajectory with usable retained energy. Heavier .177 pellets up to roughly 10.5 grains suit higher-power rifles aiming for more downrange energy.

What weight pellet is best for a .22 air rifle?

A 14-16 grain domed pellet is the standard weight for a .22 air rifle used for hunting or pest control. Full-power PCPs can run heavier .22 pellets, up to around 18-21 grains, for more retained energy at 30-40 metres.

Are flat-head pellets good for hunting?

No, flat-head pellets are built for paper targets, not hunting, because their poor ballistic coefficient causes fast velocity loss and more wind drift past 25 metres. Domed pellets are the better choice once a shot moves past close range.

Do hollow point pellets work for pest control in Ireland?

Yes, hollow point pellets work well for close-range pest control on rabbits and similar species under roughly 25 metres, where their expansion adds stopping power. Past that range their lower ballistic coefficient makes domed pellets the more reliable choice.

Does barrel twist rate affect which pellet weight to use?

Yes, barrel twist rate affects pellet stabilisation, and a barrel cut for lighter pellets can under-stabilise a heavier one and open up groups. Matching pellet weight to the rifle's twist rate matters as much as matching it to calibre.
