This is similar to what I've always loaded, however I'm finding that the 4350 powder has large inconsistencies in extreme weather differences. It shoots great for me at +10 C, but at -30C it doesn't group so nice anymore. Does anyone else find this? I've got several hundred cases trimmed and primed and ready to go but I'm wondering if there are better choices for powder.
This may be true with IMR4350, but H4350 is temperature insensitive and is good to go in the cold.
