Dogger: I have been using Nosler Partitions VERY successfully for going on 58 years now and I have yet to find any reason to be dissatisfied or even be tempted to try anything else.
I have used them from Alaska and Alberta on down through Utah and Wyoming taking all manner of Big game with them.
In the "lower 48" specifically I have used them in Washington, Oregon, Idaho, Wyoming, Montana and Utah.
Hoping to add Caribou to my already long list of Big Game successfully harvested with Nosler Partitions.
Long live Nosler Partitions.
Hold into the wind
