I started using Partition bullets shortly after I began reloading. We're talking 4½+ decades here!
At that time, they were made out of a "bronzy" material, and had a relief groove cut in them, just over the Partition.
I have shot over 100 head of game with the Partition. of that number, I have recovered about 20%, the rest making exit.
Now, I will make it clear that I have shot a lot of animals with other bullets as well. Some C&C, some bonded and now, the monometal designs.
But I still use the venerable Partition, simply because it works, period!!

You can get the picture, I'm sure. Call me a Fudd, if you want, but I have the utmost confidence in the Partition.
When I went on a late Elk hunt last month, I was packing one of my 308NM rifles with the 180 Partition loaded.
Again, the proven bullet did it's job...one shot at 276 yards, DRT.

What is not to like?
As you can see, though, I am not Exclusively a Partition user, and freely acknowledge that there are many very
good bullets available to use today.
One of the very good things about our time right now, is if your rifle does not like a particular premium bullet, we
have plenty of options to go for. When the Partition was basically the only choice, if your rifle didn't shoot them, you
were hooped, and had to rely on a C&C bullet to get the job done. [in most cases, they did OK as well, just reduced your versatility]
Sorry for the long post, but the Fudd in me just had to speak out.
