[QUOTE="Kansaswoodguy, post: 1176945, member: 83267"] I like to find a load that shoots reasonable well then run an OCW test not for powder changes but seating depth with a given bullet to see where the gun likes that bullet seated. Then I start my OCW testing for powder charges if all this can be done over a chronograph so much the better it will show you the low SD nodes that almost always line up with the best accuracy loads. The trouble is that at 100 yards your targets don't always agree with the chrony I am not sure why this is but I have seen it many times with myself it maybe a mental thing in fact I'm sure it is. When I find the low SD load it will more often than not be an excellent long range load. I trust the magneto speeds numbers more than my coffee shaking OCD $ss at 100 yards. [/QUOTE]
