Are these cylinders safe for Colt/Replica only or can they handle Ruger Level loads?

What does the manufacturer say?

All Kirst Cartridge Konverters™ are precision CNC machined in the USA from 4140 Steel and heat-treated. The cartridge conversions are rated "For Black Powder or equivalent loads only," which includes the current Cowboy Loads on the market. .45 caliber cylinder conversions must NEVER be installed in a .36 caliber revolver. The Kirst Converter must NEVER be used in Brass Frame Revolvers.
