Well it's done! The evil thoughts put into my mind by you blokes has finally prevailed....
today I took a deep breath, picked up the phone, pulled out the card and purchased a Ruger #1 in .500 NE. Between it, the 16 bore cape gun and the 9.3 x 74 Baikal u/o DR, I should be able to keep myself amused for a while working out loads etc. You really are a bad influence. (just joking)
Now I wonder which will arrive first???

All the best, Ian.
