Wow, I din't know that. Thanks!

You can long load cast bullets in the 480 to the same COAL as the 475 linebaugh, hence same powder capacity, so there is no need. Asside from that, the DA grip is absolutely brutal at 475 Linebaugh levels, and I think you'd find the gun unshootable. I like 400 gr @ 1200 fps from the 7 1/2" 480. I've seen my buddy push them 1350, and have known others reaching 1400 fps. I've also seen those guns in recoil, and I have no desire to shoot such a load. If 400 gr @ 1200 fps isn't enough, I'll take a rifle thank you very much.

As far as Wild West, I their prices are too high for the quality of their work, and they have been known for being rude to customers and prospective customers. I would never have them work on my guns, but thats just me.
