Last safari we used 165TSX in Mrs Blacktailer's 308 Kimber. I don't recall what velocity I loaded to but it was not max by any means because I didn't want to beat her up with recoil. Did fine on zebra on down. The TTSX should work very well.
I am continually astounded at how quickly people make up their minds on little evidence or none at all. Jack O'Connor
