Trying to find the coals for nosler partition 180 factory loads. Can't find them anywhere. Any help?

I have never had my hands on any factory ammo for the 300 WSM that was loaded with Nosler Partitions.

However, when I bought my 300 WSM I tried some Winchester factory ammo loaded with the 180 grain PP. The overal length of those loads was 2.745".

The SAAMI over all length listed for the 300 WSM is 2.86".

That is what I wound up loading my 180 Nosler reloads at, 2.86".

Hope this helps, RF
