At those figures your fine :yes:

 

You should have asked them to chrono it with Bisley Magnums. If they set it to no more than 11.5 with Bisley Magnums you know you wont go over the limit with any 'readilly obtainable pellet'

 

Having said that; at 11.03 max with AAF's, its unlikely you will reach the 12 limit even with a BizMag, so don't worry :D

If you went out shooting with it , do you think you`d notice the power being `slightly` ( as it is only very slightly ) low ?? Do you think after its `run in ` it`ll be better ?

 

Chrono`s are good to keep an eye on power , but people get obsessed , leave it be and concentrate on putting the pellet where it needs to go .....

dondon000 you worry too much all of those readings are fine and you have nothing to worry over, infact they are a nice set of figures. Why would you think you would need to send your gun back?

My advise is for you to go out and enjoy your beautiful purchase and to use if for what you bought it for (hunting or targets), ENJOY, have fun and stay safe.

As part of the Gun Trades Anti Tamper Campaign - Manufactures set the power lever and seal

 

Aware thast other pellets will increase power

 

Air Arms are set with own pellet Range

 

Try different pellets -

 

Pax Bullet pellets fly faster - Bullet Shaped not Shuttlecock like Wasted Pellets and hit home hard

 

Well worth giving them a Try - in Air Arms need 4.50 Head Size

 

BOB/R

 

As returning it will not get power turned up

 

Trading law states gun being suitable - High power can be achieved with different Air Gun Pellets

If you fill to 190, then with a chronograph fire shots over, record all the readings. Then you will see the guns "sweet spot" where the output is at its flattest, that is what pressure you need to fill too. By reording your readings you will see to what pressure you need to fill to and you will also see how many shots that you have in the guns "sweetspot".

when i had my huntsman new, it was 10.6, i was happy with that as it was consistent, it then crept up over a course of the year to 11.9 mate...i didn notice any diffrence in power creep, neither did my quarry? lol the main thing is accuracy, consistency to gain good or reliable accuracy too. i wouldnt worry. 1500 pellets is nothing lol
