Thread: Some advice sought for 30-06 loads.

There are differences in ogive shape between secant (SST) and conventional (sierra) bullets.
I am loading 180 SGK's and testing 165 sst's as well.
My experience so far is that the sst like to be at least touching or lightly jammed to get good groups.
My questions relate to others experiences indicate little or no jump in 30-06 loads, or various degrees of jamming, and whether there are variations of pressure that affect grouping consistency with the two different ogive shapes.
The barrel I am using has a short throat, with bolt face to lands 2.571". Norma brass.
Thanks for input in advance.
