RE: 300 ultra mag load
3DNWV, I was getting 3300FPS. Freinds are getting crazy speeds with Norma MRP and Rel 22.
Last weekend at the range, a buddy was using 95.5gr Norma MRP, 215m prim, and getting 3550fps using 180gr scirr. with .90 groups at 200yds. I told him he sucks. My rifle hates the Scirrocos, and thats the bullet I want to work the most for my moose trips. Watch out with Scirrocos, they build more pressure than your partitions, GS, and such. He, nor I ever saw pressure signs with Noslers, or Speers all the way up past max load, but I saw them with Scirrocos, up to 95.5g of H1000.
As far as this being a deer bullet, I have seen small exit holes in 90lb doe with scirroccos but major damage when the shot was not broadside (thru the chest and out the ham) Seems these bullets take a little bit of meat to expand.
