I have a custom Super Redhawk in .475 Linebaugh. It is lighter in weight, has no break, and kicks considerably harder than any .460 I have shot even with heavy loads. The one red dot-type sight I would recommend is the Ultradot (
www.ultradotwest.com). The Ultradot 30 I have is only 4-ounces in weight, comes with a lifetime warranty, and has withstood thousands of full-tilt .475 Linebaugh rounds without a hiccup. It has even fallen out of a 12-ft ladder stand with no issues. Best of all, they are $145.00 shipped. Fantastic bargain! I have a good friend with Ultradots on his BFRs in .475 Linebaugh and .45/70 and they have put up with virtually thousands of rounds. Personally, I would look no further for your .460.
