seroadglide,

I have good luck with H4350 in my 9.3x74.

It looks like yours is regulated for 15 gram bullets. I am surprised you are getting the Speer 270's to cross. You must be putting a pretty hefty charge in it.

Have you tried any 232 grain (15 gram) bullets?

My rifle is regulated for 15 gram bullets. I am using the 235 grain Hawk bullet with 70.0 grains of H4350 and a CCI 250. This load shoots well and seems to be very moderate pressure.

Good luck with your rifle.
