Ovny, since the .500 NE is OK in Spain (I checked in Madrid) I am surprised the .500 Jeffrey and the .505 Gibbs are not allowed ??? Would it be that they are used in magazine rifles or is your info incorrect, best, Mike (p.s. you nearly gave me a heart attack since my new rifle is in .500 NE)

p.s. do you have a rifle range in Madrid, if so on my next trip up there I will bring a few rifles and we can go and put some ordnance down
