Stirrup pumps are easy to use when there is some charge in the rifle I.E. 100 bar, as it doesnt take long to get upto the 190 bar level to be fully charged. However, when the air cylinder is completly empty (brand new rifle) it does take some work. My two rifles never have less than 100 bar in the cylinder so it is easy to top up.

On the other hand, filled a buddy bottle the other night and the good lady thought I was going to have a heart attack !

I must admit, I am looking at buying a 7 ltr 300 bar bottle in the near future, it is so much easier and quicker to fill. !!!
