Taking my best friends son on safari in June, he will be shooting a M70 featherweight in 30 06. Does any one have any info on the use of the Barnes TSX in 165gr or 180gr bullets and there performance on plains game. Biggest he will be after is Kudu. I want to shoot factory ammo...maybe Federal Premium TSX. I'm taking a Sako Mannlicher 375hh, probably won't shoot it, maybe a Zebra, it just has to go to Africa for its first time.
