I used one in 1998 with H4350 and the then 210 xbt. It was clocking right at 3200fps. I killed zebra, impala, blesbuck and then went over to Namibia and shot the big gemsbuck. They are as big as a spike elk, big cow elk. I later on, in 2007 used its "twin" ( as far as I'm concerned) the 338 RUM and 180 NAB/H4831 340w is a fine round, and I too would start with the 185 TTSX or 180 NAB. Have a ball pard!
