got gun back today,engineer said there was far too much pressure in the gun, there was 260lbs of pressure in the gun, where there should only be 160lbs. He said i was very lucky, at least now i know that the gun and stirrup pump are working, i have learned a hard lesson, as has my wallet, the cost was £70, then i came home and i was enetering the house the gunbag snapped, so i had to go back to the shop and purchase a new gun bag., so all in all an eventful and costly day it has been for me.
