Have the Nosler Partitions changes much in their design and construction over the past 10-15 years???
About that long ago I found them to pencil through deer out of a 270 that was moving along at 3050fps. Accuracy with them was so so but then again that rifle produced accuracy that was so so also.
I haven't seen much change in the 6mm,, 270, 7mm, or 308 in recent years. Of course, I haven't tried all the weights the Partitions come in with those calibers.
This year I had a .270 size exit hole with a Partition on a 500+ lb bull at ~50 yds. But it first broke the onside shoulder and obliterated the offside leg bone before it exited. Probably the back half of the 160 gr was the culprit..........
