You might try Speer data for 220 gr bullets since they don’t make a 225 gr .358 bullet. I get a chronographed avg MV of 2,723 fps out of a 22” 1:16 twist barrel using less than a max listed charge of CFE 223 with 225 gr Partitions. Very accurate load and no signs of pressure in my rifle. All .270 Winchester’s should be rebored!
