Rubberhead,
Very pretty rifle! I know of a couple of hunters with the same O/U in 30-06 and they are happy with them. Bushveld offer is a good one and you may enjoy visiting with an experienced gun maker.
My .405 WCF Simson Suhl double came to me regulated for a 300 grain load slower than I shoot in my 1895 .405 lever gun, so I took it to a competent gunmaker and it is now regulated to use the same ammo as my levergun. It puts 4 shots into one inch at 50 yards and I rarely need a second shot with the .405.
