Thanke for the reply. I quess I don't really need to load the old girl that strong. Nosler calls thier strong rifle load with the 300 grain partition at 35000 lbs chamber pressure. Thats a healthy load but far below the Ruger Load of about 50000 lbs. Many of the Encore chamberings exceed 50000 lbs. The Marlin load is plenty of whop. I shot clear through a 500 lb + Bear and he went down so fast that he stirred up a cloud of dust and leaves. 350 grain Hornady round nose @ 1900 fps. I need to work up a good load for the Encore as well as the new G2 carbine in 45-70. That one I will just load to trapdoor levels. Thanks again.
