The 150gr .311 SP Sierra bullet shoots nice from SKS or CZ 527 people want something like this for deer,black bear and yes moose over the 123gr which works fine for the first two species haven't tested it on rubber nose as of yet. Likely not out until 1st or 2nd week of Nov. half way through the AB hunting season.Timing not so good for those who don't reload.H4198 /H4198/D4198 followed by RE#7 and H 335 is best in this cartridge.
