I've had a camera failure due to the dust in Kenya, four of us all had to visit a camera repair shop in Nairobi. And had two load/bullet failures in Zimbabwe. But no rifle failure.

The batch of bullets (180 gr Nosler Partitions - .30-06) were failing to open up and acted like solids. Luckily had 200 gr loads as well and they worked much much better. The batch of 180 grs must have been a perculiar lot as no one else seems to have had a problem.

I neglected re-size my .375 H&H necks on another trip and they were moving in the magazine under recoil which caused me some problems as well.

The scopes and rifles all worked very well as they were well tested before hand. I think the whole package - rifle, mount, scope and ammo needs to be in balance and well tuned.
