I might need to order some of those for the Hornet and 223 bolters. The CZ-527 dotes upon Lyman #225438 atop 9.0 grains of 2400, and the Ruger 77RC likes RCBS #22-55-SP over 12.0 grains if IMR-4198.
ETA--Reed's has some interesting cast bullet offerings on their web page--thank you for bringing their info to light.
