Hey Tony, I see it didn't take you long to get over here! Welcome aboard, you will find as much expertese regarding double rifles, as well as big bores of all types on this web-site, as you will any place in the world today. You will likely get some good advice for loading the old 500BPE
here as well. Many of the guys posting here are on Accurate Reloading as well, and if you can't find it on one of these two sites, It doesn't exist!

I'll try to get down there soon, maybe to see Mark, so we can do some shooting! How does your little Chapuis shoot?

Again, welcome, and good luck on your Muledeer hunt!
