Alberta, I have used those in 62 and 74R for 10 years or so. They are just plain great at 62 and even better at 74R velocities. You can always expect exits at broad shots on elk size animals and full length penetration without exits on frontal shots. No damage on smaller animals like roe. And IMO one of the best bullets when shooting through obsticles (regarding keeping straight line)...

Ganyana from Zim, has a straight 38 Cape Buffalo 1 shot kills with TUGs in 62, tho he claims there are better Buff bullets around these days he wouldn't mind using them still.

Have in mind those all apply to 62 and 74R velocities - things may be different with 64.

P.S. Here is the only one I have managed to get so far - "Texas" heart shot on Impala - entry on hip, bullet was found in the windpipe:
