you mean you have to do some homework PRIOR to actually shooting ?
who would have guessed!

After burning up lots of components over the years, I took a different approach and it has saved me lots of time and components. What used to take 100+ loads to find the best load now takes less than 30 or 40 normally. Sometimes far less if I do my homework first and decide the type and weight of the bullet I want to use.
I will select the powder that reaches the max pressure at 100% case capacity and the recommended primer. I will load 3 rounds of this powder in 1/2 grain increments starting some where below the middle load listed for the bullet weight I want to use. I also found if I used the bullet I wanted to end up shooting I also saved time and money. (I used to use cheaper bullets while testing).
I test with a clean barrel for every load, and shoot through a chronograph. If get a poor SD on the second round, I Abandon that load and save the one I didn't fire for one fouling round each test load.
When the SDs drop to less than 5 or 6 I know I am close and may load some in .02 Tenths grain to see if I can improve the SDs. This process shows me that I have a good powder, primer and case capacity combination.
Armed with this information I start looking at seating depth and bullet design (In the same weight) to get the accuracy down.
after I get all of this accomplished all that is left is to tweak the load
and start shooting.
This has worked every time and I have gotten sub 1/4 MOA groups in less than 25 shots And not shot out a barrel doing so. Some of my best loads have been less than 10th MOA in as many loading's.
This may not work for everyone but it has saved me lots of time and frustration.
Just the way I work up loads for accuracy.
