I haven't used a 30 carbine revolver nor had any feedback from customers, as there aren't many of them in circulation. However, I believe I'd give my FN in 130 gr the first try, and would probably not change even if weights to 150 gr were accurate. With the small frontal area 1500 fps is needed to get decent killing punch, and more is much better. A 130 gr will get this velocity easily.
I've killed quite a bit of game with a 30 carbine, 10 inch twist, in a single shot handgun which I built many years ago. In it I favored 160 gr started at 1150 fps. These were pure lead softnose bullets with hollow points. I took probably around 10 deer with it, and the farthest any of them traveled was I believe less than 50 yards. The gun would drive 200 gr cast bullets at 1800 fps quite comfortably, this with 12 inch barrel, but I shot it with my thumb knuckle pressed into the hollow of my cheek, which set the rifle scope at the proper eye relief, and steadied the back of the gun. Recoil tolerance set my limit at 160 gr/1150 fps, as the cheek isn't the proper place for heavy recoil!
I've wandered away from your revolver question because I give personal experiance, which is single shot with the carbine. This is a horrible under rated cartridge when used in a strong handgun. Your Ruger will certainly drive 150 160 grain bullets into fine accuracy if the twist is at least 1 in 12. My single shot was a cannon breach, which held the ctg at 0 headspace, and was capable of standing 60,000 psi without the slightest strain. .
