I read the article, certainly interesting. I will be curious to see how the 480 ruger fairs, once it is loaded to its potential w/ heavier cast bullets. I have a feeling it will suprise alot of people, once they find out what it can do. Can't wait til I get mine! As the article mentioned, bullet weight is more important then velocity, and the 480 is only ~200 fps shy of the 475, but at the same time, recoil is suprisingly manageable.
The author mentioned trying the 535 gr in the 500 linebaugh, I dunno about that! The 440's definately get your attention.
As much as I like the bisley's, I must say I've been pleasently suprised with the SRH. The fealt recoil isn't bad at all, and the accuracy is steller. My buddy was shooting at 50 yds today, from a rest and scoped, best group had all but one shot touching, still, the group was 2" @ 50.
I believe the 480 is rated at 48,000 psi, though I personally would try and keep it at 35kpsi, for reasonable recoil. As I've noted before, the cylinder is longer then a 475 linebaugh, so with bullets that can be seated out, you have more capacity then a 475 linebaugh!
Anyhow, why spend $2k on a custom, when you can get a factory gun for $600, that shoots every bit as well.
