Why are you getting 12 ft-lb air rifle,why not just get a rifle shooting a bit harder.I had a gamo in 22 and I got a fella that was into Airsoft and had a chronograph and we measured it was putting out between 18-19 ft-lb.

I used to shoot rabbits with it around the 40yrd mark but would always go for head.If I was buying again I'd go .17 as the 22 was a bit loopy over 50yrd for crows and they are hardy yokes.Id have one in the safe if no licence was needed.

I used to chest shoot crows with I think jsb Jumbo's at max 50yrd and most dropped on the spot but some took off then fell from the sky.

I would never have tried head shooting them as their head is a small target and I knew I wasn't a good enough shot.Mine was a Springer so not the best you can buy in comparison to PCP rifle's .

I also used it to dispatch mink in cages and it did the job fine and safely

if this link works "extremetaz " gave a good comprehensive answer on the subject on 18/2/18.

You'll need to be a sharp shooter to head shoot a crow at 40yrds with a pellet, any breeze and your missing. 12ftlbs on crows will have to be head shots so I'd say about 20-25yrds. Stick up a €1 coin size target and see can you hit it 100% each time at different distances. As said above if your going to go sub12 ftlbs a .17 might be better as there is Savage drop in a .22 sub12 pellet. If it were me I'd be going with an FAC .22 and shoot jsb hades or h&n barracuda hunter extreme pellets which will be up around 30ftlbs and chest shoot out to 50yrds. From first hand experience they will drop on the spot. Using domed pellets won't drop them with chest shots at that distance as they don't dump enough energy. Crows are hardy and need a good shot placement to drop them. No point taking pop shots and birds flying off to die slowly. In the end, HOW FAR is as far as you can hit a €1 coin 10 out of 10 shots without missing, that will tell you the distance

I zero my fac at 50yrds. About 1" drop from there to 60. I wouldn't shoot past that and it would have to be ideal conditions if I did. You'd have a second zero at about 20yrds and anything between 20 and 50 you'd be holding under. Shooting up depends where you are, if you know there is noting between you and say 200yrds then the pellet will have lost all energy by then. Of course its not recommended to shoot up but if you know its safe...make your own mind up. I shoot pigeons in barns with jsb hades pellet and on full power at 15yrds and they dump all enery in the bird with a chest shot and will not hole sheeting at that distance. 50yrds is a long way resting on a gate or a wall or sticks, sitting at a bench with bipod and sandbag is easy but real world shooting with air rifle requires good shot placement as there is no ballistic tip to blow up, your relying on hitting vital organs to kill the target.

No, for hades and hunter extremes you want speed so that when the pellet hits the target it dumps all its energy on impact. 16gr at 900fps is lethal, busts pigeons or rats. No, no time for slugs, if I want slug capabilities il go buy a .22lr again. Slugs are a gimmick in air rifles

Fx crown. I've had others over the years. Around 70 shots for 250bar fill

480cc. I run a 380mm barrel. More air required the shorter the barrel. 600mm barrel would double that shot count. Assuming. 22 of course

Yes, that's how it works. Longer barrel creates more speed with same amount of air used with short barrel. So if you want to send a pellet at a given speed of 900fps then you must use more air behind the pellet with a shorter barrel to achieve this, add a long barrel then less air is required to get same speed.

Can't answer that 100% but I'd reckon 1000+ shots maybe close to 1500, not sure though, never actually done that test

12ltr 300bar

Agree with fiestaman,the fac pcp’s are lethal stopping power…Ive had air arms heavy 18gr .22 dome pellets drop grey crows stone dead at .50y and pellets go straight through the chest cavity and exit.Speaking from experience with the pcp headshots on any quarry be it rats crows magpies ect are the norm it just takes patience/concealment for the quarry to be calm enough to keep the head still for a few seconds.My rifle is the Air arms ultimate sporter variable power,awesome tool it is,I can shoot rats all night 80-90 shots on power level 2 or when longer distance is required usually shooting magpies/crows i up it to power 5-32ft lbs but obviously lowers shot count to about 30 shots per fill.

I know air rifles have their place, and I've had some. But with the availability of various 22lr rounds, the 22lr is better and cheaper.

Ratshot, and the myriad of 22 bullet grains and charge loads that mimic an air rifle, make it extremely versatile.

I don't have one at the moment, and miss the ratshot for inside sheds, using a 17hmr for rats at the moment and I hit quite a few during the year around farms.

Paying for scuba tanks etc just makes it more complicated, expensive, and the bloody drop of air rifles ballsistics is frustrating to say the least.

Regardless, I really appreciate a springer or gas ram as an all in one package.

12fb air rifle at 40y the pellet is hitting at a very steep angle, at least 30 degrees, more even, IMO. You need to know the distance very well to adjust your poa

adjusts the power

what gun have you i have a fx dreamline screw in hammer spring to increase power out to decrease power if you want more air you open the regulator a bit.

Increasing the spring tension gives a few more microseconds to allow the regulator to dump it's air. On the upper end rifles like the FX the regulator is actually adjustable anyway and is the best way to increase power. On older PCP's the power of the hammer was important as many did not have a regulator , just a simple knock open valve so the 'dwell time ' was a fraction longer.

Don't have an FX but all the FX guns look great. I'd say a power level of about 30 ft/lbs is optimal for farmyard shooting. A good source for compressed air would be handy and the cheaper Chinese compressors have come down in price in recent years.

Exactly. FX led the way by fitting a pressure gauge just for the regulator. Check out AirArmsHuntingSA on the tube for what can be done with FX rifles .They seem to wind the regulator up to 120 bar and beyond and get unbelievable results.
