Nosler Partition "Jump"

[idahohunter8]

I realize that every barrel/chamber/caliber are different...but typically do nosler partitions usually like to have more or less jump to the lands?

In my 270 the chamber is a tad loose so I have always loaded to max mag length and done fine - never measured by assume there is not too much jump.

Treat Partitions as you would any cup and core bullet. I typically seat Partitions at 0.010 inches off the lands. In a few selected instances I seat them at 0.020 inches off the lands. Generally speaking, Partitions yield excellent accuracy in a rather wide variety of cartridges in my experience.

I have had good luck loading PT's .015-.025" off the lands.
My 338 RUM is loaded to just under the magazine length with a lot of free bore and it shoots under .5 MOA.
Guess it just depends on the rifle.

I learned from the doc and I've yet to see this method let me down.
