I liked the old original Barnes X-Bullet 350-grainer.
I used it in a Ruger No. 1 .416 Rigby at about 2700 fps MV
to take a water buffalo steer that weighed about a ton at range of about 100 yards.
It was at a Tennessee game farm in September 1999:
Above, my laser range-finder operator is on the right.
We gave thanks to the water buffalo with the Crocodile Dundee Water Buffalo Salute.
On same grocery trip I also took a fallow deer at 342 yards, with same bullet, and laser range-finder.
It was a doe weighing barely 100 pounds.
I do believe the TSX version or even TTSX version of the 350-grainer can do the same in a .416 Remington,
only requiring a higher pressure than the .416 Rigby to go 2700 fps MV.
SAAMI allows up to 65,000 psi in the .416 Rem.Mag.
How convenient and reasonable.
The 350-grain/.416-cal. TSX is a do-all bullet, just saying, again.
Big Red was his pet name at the farm and he wore ear tag number 8, in September 1999.
The next buffalo I killed was in Botswana in late July 2001 using the Ruger M77-RSM .416 Rigby
with a 380-gr GSC FN at barely over 2500 fps MV.
The bullet zipped right through that cape buffalo smashing big shoulder bone and heart and lungs.
That load could be duplicated with a .416 RemMag, if you could find the bullets.
That was about 6 weeks before all hell broke loose on 9-11-2001.
I was working in Connecticut then, right across Long Island Sound from where it happened,
about 50 miles away.
I was making rounds in an ICU and watched it happening on a comatose patient's television.
HELL I WAS ALMOST THERE, paraphrasing Elmer Keith.
