Like everything there are many ways to skin a cat/work up a load.
The way I start is with a good loading manual and the bullet that is best
suited for the game. Then I look for a load that gives me 95% to 100%
load density at or near max pressure.
After doing all of the case prep I start loading with the powder and primer
listed with this powder,bullet,primer combination 2 grs below max.
I load 5 rounds at -2gr of max, then 5 more at -1-1/2grs then 5 more at
-1gr below max ,and 5 at-1/2 gr of max and finally 5 at listed max.
Then I go to the range,set up the chronograph and start shooting.
I will shoot the first round (2grs under max) and look at the brass,velocity,
bolt lift and the primer and if everything looks good then I will shoot the
remaining 4 and look at group size and standard deviation. Log all of this
information and move to the next hotter load.
I repeat the process used in #1 and look for changes from load #1 to load
#2 group size,velocity,pressure, condition of brass and Standard deviation.
Repeat process with load #3 watching for signs of pressure.(Flat primer,heavy
bolt lift).This process will find the max loads safely.
At the first signs of MAX pressure I stop the process and review all the data
and decide if this is a good load to work on.
If I have good SDs and groups I will go back to the loading bench and load
2/10ths each side of the best load to find the sweet spot .also I will try
different primers with this load.
After all this is done then I will play with seating depths to get the best accuracy.
Like buffalobob said it takes time and may not be fun but it is worth the effort
if you want to get the most out of the rifle/pistol.and you will be amazed at what
a small change will do. so keep lots of data for review.
Just the way I do it
