I too am a fan of the Barnes bullets. It doesn't appear you reload but you can also buy loaded ammo in the form of the Barnes Vor-TX. Looks like it comes in 150, 165 and 180gn loaded with the TTSX or TSX.
I have loaded the the Barnes for many years for myself and a friend who was on the Marine Corps rifle shooting team. He was sold on them the first deer he shot. They are easy to load accuractly and you nearly always get complete penetration of an animal and if you like that then you will like the barnes bullets. A lung shot or shot to the vitals often turns them into a soup. I think it may have something to do with the way the bullet expands and forms large sharp petals. I figure the bullet is still spinning fast when it hits and the spinning petals going through vitals at high velocity basically churns them up kinda like a egg beater would. You usually get a very good blood trail. The only exception I have seen is with a high lung shot where the animal bleeds out but mostly bleeds into the lung cavity but either way they don't go far. Also, on occasion the bullet will try to pull the vitals out the exit hole sometimes plugging up the hole. Buy my friend and his wife being they shoot from stands, have accurate ammo and rifles often take neck shots at under a 100 yards which is instant death. I'm talking deer here though not Elk. I have done the same myself and the few I have shot that way don't take even one step, they just collapse where they stood. Only negative about that is that the heart instantly stops beating so the blood doesn't get pumped out of the animal.
That all said about Barnes there are other fine bullets as well. For my 300 Win mag I load 210 grain Matrix VLD hunting bullets. Berger also makes a similar bullet but when I was first loading them Berger didn't have a 30 cal bullet that heavy. Matrix bullets are made by a small company in Canada and they make great bullets.

Attached is a 210 Matrix VLD and on right a Barnes 175 gn LRX bullet. The Barnes LRX is the long range version of the TTSX being slightly more aerodynamic. Barnes also makes a 200 gn LRX bullet which has slightly better BC than the 175 gn.
