I used a Super 14 in 7-30 Waters for a while.... Like Lloyd Smale, I used the Nosler 120 gr. Ballistic Tip. I was satisfied with its performance on the few game animals I took with it -a couple of pronghorns, a couple of blacktail deer, and one of the biggest mule deer I ever shot. I killed more feral goats and pigs with it than anything, and the bullet worked just fine for me in taking them. Accuracy was great, too.
I'm a huge fan of Barnes X Bullets and was an "early adopter" with my .270 WCF, .280 Rem., .30-'06, .300 Wby, and .375 H&H rifles, and later with .223 when they started making those.
But personally, with the kind of impact velocity you get with a 7-30 out of a Super 14, I don't really see the need for anything more wazoo than old school cup and core bullet technology. I only have so much money to spend on my shooting sports hobby, so I'd be inclined to stick with less expensive Nosler 120 gr BTs because I can shoot twice as many of them for the same money, and I don't think the more expenisve Barnes Triple Shocks would be that great of an advantage in what is a modest velocity round.
