Fitz.......be extremely careful what you read in the replies to your post. CanoeontheYukon has it right. For a 215 gr bullet with a gas check such as the Lyman 429215, the starting load for Unique is 6.3 gr. The MAXIMUM load is 7.7 gr giving 884 f.p.s.and 13,600 Pressure C.U.P. This is from the third edition of the Lyman Cast Bullet Handbook. The firearm used to test was a 4" Universal Receiver. The earlier 1973 edition of Lyman Cast Bullet Handbook gives a higher load using a maximum of 8.0 grains of Unique in a 7 1/2 inch Super Blackhawk. The Ruger Super Blackhawk is one of the strongest actions you will find. I highly recommend you get a reloading manual of your choice and begin with the suggested starting load and work up from there giving close attention to primers after shooting to examine for excess pressure. I would never take someones recommendation for a load without verifying that load with a recognized reference source.
JMHO.

Mike
