If what you are looking for is load data, I would (and have) relied upon on line sites for the various powder manufacturers for their products. There is such a wide variation minimum and maximum loads anyway among the various sources that we have to do our own homework in finding the best load for a particular bullet with a particular powder. Alliant is the only free load book that I have seen that gives the recommended load for a particular caliber, but even that needs work since it will be listed for a particular twist and barrel length. Nosler's manual will give a "best" for the particular Nosler bullet, with the same caveat about twist and length.
What i do is as follows with a new bullet or powder.
1. Do seating depth test as in Berger article, lands, then .04 apart off the lands.
2. With my best, I then take the minimum and maximum loads across all the manuals and on line date available to me.
3. I then do 4 shot groups at 100 yards with .4 grain difference between groups from minimum to maximum. BTW I have a .223 Savage F/TR w. 7 twist and 30" barrel.
4. I pick the best and then narrow down between the best and .2 increments both ways on another day.
5. Then, on another day, narrow down until I get either a perfect or near perfect load.
I found that my best loads bore little relation to recommended loads from some makers or the maximum or minimum for a given manufacturer of powder or bullets.
I NEVER exceed the maximum listed in any powder manufacturer's range.
