Not a double rifle, but I had Reto Beuhler do a fitting befor he built my 404 Jeffery. I like my shotguns at 14-7/8" LOP and the Jeffery came in very close to that measurement. Shoots like a dream and I killed two bull Buffalo with it in Tanzania last year. Longer stock keeps your thumb a bit further from your nose, which useful when firing a heavy rifle.
