@Rule 303 I can safely get 2,440 fps out of my Whelen with 310s and a healthy dose of 2209/H4350. The Rigby should be able to do 2,500 to 2,600fps easily.You seem to be missing the points we are making. You are talking about nostalgia, others are talking about practicality. Looking at your pic you can see the bullet is seated very deep into the case. How would a Woodleigh Hydro or other Monometal solid go in your rifle. Probably would not get enough powder in to achieve the 2200fps. It would be the same for the 350Rigby, its muzzle velocity would be the same as the Whelen's with same projectile. Why drop 358 Norma performance down.
If you wildcatted the 350R and blew it's case out so it had very little tapper you, would I think, match the 358RUM (another wild cat) performance and you need a magnum length action for that.
