Gamo GX-250 — High Shot Count PCP Air Rifle

Gamo GX-250 Review — The High Shot Count PCP

The Gamo GX-250 is a pre-charged pneumatic air rifle that combines the best elements of Gamo’s popular GX-40 and Coyote models, creating a hybrid that offers both a higher shot count and affordability . Available in .177 and .22 calibre, the GX-250 features a 500cc air cylinder delivering approximately 120 shots in .177 and 135 shots in .22 per fill — a significant upgrade over the GX-40’s 40-50 shots . The rifle is fitted with a BSA cold-hammer-forged barrel, the same precision component found on more expensive British-made PCPs, ensuring excellent accuracy out of the box . For shooters wanting a PCP for pest control or range work without needing to carry a pump or tank into the field, the GX-250 offers exceptional value.

Gamo GX-250 UK — Specifications and Features

The Gamo GX-250 UK market receives the rifle in sub-12 ft/lb configuration for certificate-free ownership. Key features include a lightweight, ambidextrous synthetic thumbhole stock with textured grip panels for positive control in wet conditions . The bolt-action system is smooth once broken in, cycling pellets from the 10-shot rotary magazine . The rifle includes a two-stage fully adjustable CAT (Custom Action Trigger) with a manual safety blade positioned forward of the trigger guard . A pressure gauge is fitted to the front of the air cylinder, and the 1/2 inch UNF threaded muzzle accepts standard silencers. Overall length is 1120mm, barrel length is 470mm, and weight is approximately 3.4kg (7.5 lbs) . Maximum fill pressure is 232 bar .

Gamo GX-250 Package — What’s Included

The GX-250 is available in several package configurations. The standard kit includes the rifle, a Gamo silencer, a 3-9×40 scope, dovetail scope mounts, and a fill probe . Some retailers offer the package with a BSA-branded scope, while others include the complete starter package with a stirrup pump. The Gamo GX-250 package price varies depending on the retailer and included accessories, but the rifle consistently represents excellent value in the entry-level PCP market . For those who already own a pump and scope, the rifle-only option may be available from selected retailers.

Gamo GX-250 Problems — Honest Owner Feedback

The GX-250 has received extensive owner feedback on UK airgun forums, with several common issues worth discussing. The most frequently reported problem is intermittent trigger stiffness — owners describe the trigger being normally light but occasionally becoming very hard to pull . One forum user traced this to the first stage adjustment screw being set incorrectly, and backing off the first stage considerably solved the problem, also allowing proper second stage adjustment with a longer M3 grub screw . Another owner reported a similar intermittent issue and chose to return the rifle to the shop for exchange .

The bolt action can be stiff on new rifles, requiring a firm pull to fully cock the mechanism. Owners warn that failing to pull the bolt fully back is a known cause of the rifle not loading pellets — the magazine cycles but the rifle does not cock . One owner described it as about the only known issue with Gamo PCPs, recommending giving it a hard pull until it won’t come any further . Another owner experienced the rifle not firing after loading, requiring removal of the magazine and re-cocking to resolve . The fill probe can be fiddly — one owner reported air escaping from the opposite side of the fill port, and was advised to pull the probe out slightly as it was being pushed in too far .

Gamo GX-250 Accuracy — Pellet Choice Matters

On UK airgun forums, owners have reported variable accuracy depending on pellet choice. One owner found that JSB pellets did not perform well in their .177 GX-250, but BSA Goldstars were a revelation producing 5p 10-shot groupings at 22 yards . Other owners reported that Gamo PCPs tend to favour harder pellets, with H&N Field Target Trophy, Baracuda Match, Baracuda 8s, and Bisley Magnums all producing good results . One owner stated their GX-250 loves H&N Baracuda 8s (8.44gr), calling it a laser beam at 30 yards with all 10-shot groups under a 5 pence piece . QYS Domed 8.48gr pellets were also reported as the most consistent by another owner . For .22 calibre owners, the Airgun World test team achieved an average power output of 11.1 ft.lb with 14.66 grain BSA Goldstar pellets, with a variation of just 5 fps over 10 shots . Field testing on squirrels at 27 yards resulted in clean kills with single shots, demonstrating the rifle’s hunting capability .
