Hello again, Mike, I live 100 Km north to Lisbon, next to A1 motorway, outside a small town Torres Novas. A sketch will help you find my place. A couple of times a year I drive down to Jerez de la Frontera to ride bikes and to my knowledge it will take you half a day each way but maybe you will find the way to combine it with some sightseeing.
I reload for my Krieghoff with 500 grains Woodleighs solids and softs. I order cases, primers and bullets from Johannsen in Germany and buy the powder - Tubal - when I travel to France or even here, where it can be found from time to time.
The legislation here was deeply and stupidly changed two years ago with the sole purpose of making it more difficult for law abiding citizens to keep and use fire arms but there will be no problem in doing some reloads as both of us own 470 rifles.
Keep in touch.
Regards
