Watto,
It works out to about 7076 ft lbs of energy. I had 80 rounds loaded by Kola at Stars and Stripes Ammo in Florida. They will load a lot of wildcat cartridges. He has loaded some hot rounds for my 585 wells magnum also. I do not have the powder charge. He would only load them that hot for a Ruger # one because of the strength of their actions. These loads are NOT meant to be used in a double rifle. Turn around time was about 6 weeks. I have used Stars and Stripes several times over the past several years. They are very knowledgeable and professional.I did not think that the recoil was all that bad. My Ruger does have a 28" barrel, a little long, but it works.
