Key Features;
- High precision shooting: GAMO’s IGT Mach 1 together with the brand’s recoil pad provides up to 74% recoil absorption when compared to standard systems.
- Steady and consistent power level: The pneumatic cylinder is always propelling the same power to the pellet.
- Less vibration: With the use of the pneumatic cylinder, vibration is considerably reduced if compared to the traditional spring technology.
- Constant and smooth cocking effort: No spring friction means smoother and more constant cocking efforts.
- More velocity and terminal penetration: You'll probably shoot supersonic w/ anything under 10 grains, so try to keep to the beefier pellets to improve your downrange hitting power, whilst not breaking the sound barrier w/ your shots.
- Improved durability: GAMO’s IGT Mach 1 has been designed to minimize friction and vibration inside the airgun’s powerplant, improving the whole mechanism lifespan.
Product Description
The New G-Magnum 1250 by Gamo is the most powerful, accurate and ergonomically designed air rifle. Spurred on by the persistent market demand for increased power at an affordable Price, gamo intentions have always been to satisfy the broadest range of consumers for whom power and price will remain pivotal factors in their buying decision.
The European heavyweight of the air gun world has surely answered that criteria by creating the new Gamo G-Magnum 1250 break barrel air rifle, which produces more energy from its IGT™ (Inert Gas technology) power system and comes complete with Gamo’s latest thumbhole “Ergogamo” ambidextrous synthetic stock.
Less Recoil with the Shock Wave Absorber (SWA)
The new recoil pad has been tested in the GAMO laboratories in order to improve the absorption measuring the force (kilograms) and the distance of recoil (millimetres), and the result has been the SWA provides up to 74% more absorption than standard recoil pads.
- ON TARGET: Gamo’s latest 49cm (19inch) barrel with an increased twist rate of 1/22 has been specifically developed for the G-Magnum 1250 thus assisting its increased velocity and accuracy.
Better Trigger Control with the GAMO Custom Action Trigger (CAT)
For the first-time, GAMO air rifle owners are now able to independently adjust the first and second stages of their trigger. Simply loosen the first stage adjustment screw and the trigger travel increases. If a shorter travel length is desired, just tighten the same screw to decrease the first stage travel length. The second stage adjustment is made just as simple; loosen the adjustment setting to increase the second stage travel length or decrease it by tightening in the same adjustment screw.
Technical Specifications;
|
Caliber: |
4.5mm / .177 cal |
|
Power |
36J – 45J / 26.5 – 33.1 ft.lbs (Manufacturer’s claim) |
|
Velocity (m/s) |
470 m/s / 1541 FPS w/ flyweight PBA pellets, although 8,44gr pellets would likely get you in the range of 1100 – 1200 FPS, though, try to keep to 10gr pellets @ 900 FPS. Your groupings will be much better this way, as will your muzzle energy,. |
|
Action: |
Break-barrel (hinging the barrel, which drives the sear into the engage position, simultaneously exposing the breech vertically, allowing one to (easily) load a single round into battery) |
|
Powerplant: |
IGT Mach 1 – basically a specialized pneumatic gas-ram inside a 33mm piston sleeve |
|
Trigger: |
CAT - you can independently adjust the 1st and 2nd Stages of your trigger. Simply loosen the 1st stage adjustment screw and the trigger travel increases. If a shorter travel length is desired just tighten the same screw to decrease the 1st Stage travel length. The 2nd Stage Adjustment is made just as easily – unscrew the adjustment setting to increase the 2nd Stage travel length or decrease it by screwing in the same adjustment point. |
|
Trigger safety |
Yes, in front of the trigger. It is a manual safety, though. Likewise, the trigger is disabled whenever the barrel is not in battery |
|
Rail: |
9-11mm Dovetail w/ rail riser factory-installed. Behind this riser, is GAMO’s proprietary RRR, which absorbs recoil and lessens scope damage, according to GAMO |
