The pressure of these new Rugers are getting pretty high in my view. 62,000 lbs

The Rigby can hold that much powder (132 gr) but no one I know loads it that much. Mt CZ shoots a 400 gr TSX or Partition at 2420 ft/s with 100 gr RL-15 in its 24 1/2 inch bbl. And at much much lower pressures.

I remain to be convinced of the greatness of the Ruger rounds. Smaller and compact - for sure. But you have to push the envelope somewhere with the denser round - pressure would be that envelope. I am sure it is safe, but your margin for error must be shrinking. I am still willing to carry that extra 1-2 lbs to allow for low pressures and long nosed bullets, and a lesser recoil.
