Cant really comment on the Combined Technology through my .300 win mag " poor groups", but have never had a problem with the Nosler BTs. Im pushing 180gr at 3100fps and never had one come apart on impact yet " nine years and several deer later" from 30yds out to 450yds. Anything larger than deer size game I would go to a different bullit though, the BTs are not made for thicker skined animals, this is were alot of the problems occur, wrong tool for the job.
