28 nosler with retumbo and 180gr berger hybrids

[cb4128]

Hey everyone, trying to find a starting point with my 28 nosler using retumbo powder and 180gr berger hybrids. Using new nosler brass, 215m primers as well.

Called berger today but didn't get anyone on the phones.

Any help would be much appreciated!

My max is 82 grains and running 80 grains of Retumbo behind both 180 VLD and 180 ELDMs. I have barrel that gets to pressure signs quick. I am also running at 3.60" coal.

Here is Hodgdon's data.

Start at 78 and go up.
All the 28's I have loaded max out around 81-82 grains
