300rum 165 loads needed

Retumbo Min. 94.0
Max. 98.0 (most accurate load tested)

RL22 Min. 86.0
88.0 ( most accurate)
Max. 90.0

This is data from Nosler Reloading Guide 6
 
I'm getting 1" groups with 165 grain Nosler Partitions and 165 grain Barnes TSX's over 96.0 grains of H1000. OAL on the Partitions is 3.585", and 3.600" with the TSX's.
 
IIRC right around 100 gr of Ramshot Magnum was the best load I found...

Never tried Reloder 22...Retumbo, I worked up to 99.0 grains with no signs of pressure, but that was a MAX load...I shoot a rem 700 sendero
