I finished a new 30 Nosler a few weeks ago and I was having a lot of trouble with ladder testing. I tried N570 and H1000. Today, I switched to CCI primers and Retumbo and that seemed to be the trick. I found a node at 86.5 grains of powder and didn't get pressure until 88 gr. Really looking forward to further testing tomorrow.

Here's a question more on terminology than your actual tests. I've seen numerous references here on LRH to "ladder tests". I'm familiar with the classic Audette ladder test method but I'm wondering if the folks here are doing some other type of test method.
 
i thought that was the scott setterley i forget his name but same thing i do that .2 or .3 and its worked well for nice forgiveing flat spots for nodes
 
There are variations of a "ladder" test
The veolicity ladder
The 10 round ladder
The POI (point of impact" ladder ( at 300 yards or longer)
Combination of the two
Round robbin POI ladder

Just use what works for you. Like they say, "All Roads Lead to Rome" Just take the one that works for you
