It's good to see everyone having so much success with the 175 Roundnose in the 7x57. My own personal rifle is a Brazillian M98 carbine (FN made) with an 18-inch barrel. The load I've settled on for the last decade or so is 49 grains of Higginson's formerly available WC852 (SL), which is almost a dead ringer for the now defunct H450 (which itself was in the H4831 ball park). I use a magnum primer.
Even with my stubby barrel, this load is pushing a Hornady 175 out at just above 2,400 and giving me accuracy under 2 m.o.a. (using iron sights).
I agree that slower powders work best with 175-grain bullets in this cartridge.
