IAshooter, unless they told you it won't work I would go with this one
https://www.jackweigand.com/raswms.htmlH2OBUG, I have a 7.5" Super Redhawk in 480 & love it.
Last year I picked up a Super Blackwawk Hunter in 44mag. I enjoy it too, but truly wish they made the SBH Hunter in 480. I'd own one in a heartbeat!
