My father in law and I just got back from South Africa. 5 animals harvested with the 6.5/284 using 127 gr barnes TTSX. All 5 animals were one shot and down within 20-40 yards of impact. I was impressed with the barnes. Was acutally surprised how much damage they did to some fairly large game. Huge Wildebeest and large Gemsbok went down 10-15 yards from impact.
