Daystate Red wolf Safari .25 cal Fac version questions

Thank you sir

I sow the review made by AOA

https://www.youtube.com/watch?v=giADviQO8Hc



and the review made by AirgunnerSA 

https://www.youtube.com/watch?v=ce-qxp_JpVI



According to AOA the shot counts are :

The .25 caliber

low power : 42 shots - Medium power : 86 shots - High power : 131 shots

The.22 caliber

low power : 20 shots - Medium power : 44 shots - High power : 103 shots

and according to AirgunnerSA

The.22 caliber

low power : 32 shots - Medium power : 82 shots - High power : 126 shots

As you can see there is a huge difference in the shot count between the two reviews (especially concerning the .22 caliber for the Medium power).

Assuming that the AOA review is the right one, I'm asked the questions in the 1st post to red wolf owners to be sure before buying the rifle.

this leed me to another question : why the shot count in the .25 caliber is more consistant thant the .22 caliber ?

Thank you for your answers
 
Meaning of FAC?


"Fire Arms Certificate". A license needed in the U.K. for any air rifle with more than 12 ft-lb of energy at the muzzle. "FAC" guns built by English manufacturers like Daystate have full power capabilities and are, for the most part, models which they export to countries which do not have power restrictions on air guns, like the USA.
