Ruger 15151,
Not if my math was correct. i dont have the figures with me but no it should not be. The Chrono numbers also do not point to a compressed load. Please someone let me know if i am wrong on the math. The bullet measures at .560 so i am showing only .185 of seating depth.

I hope you don't mind if I ask a question. If so, just ignore me I won't be offended. Maybe this should be a new thread but I will try here first.
This is where it all comes off the rails for me and I get so turned around.
I get the push test, plunk test, COL/COAL, feeding etc. etc.
According to the math, that would mean your case length is .743
I have loaded 6,000 of the Zero 125 JHP's - great bullet and very accurate but no expansion. I have switched to the RMR 124 Gr JHP and get excellent consistent expansion in water jugs and I am working up loads using BE-86 which is a great powder for what I am looking for.
I still have about 1,100 of the loaded Zeros left and use them for IDPA matches. I loaded the Zeros to 1.060 COL and I found them to be .563 in length and assuming I have a case length of .743 that would mean the bullet is seated .246 in to the case.
Wouldn't it stand to reason that if you have a COL that feeds and chambers into your guns without an issue that the seated depth should be far more important that the COL? If you are at .185 and I am at .246 I am going to have more pressure than you. It just seems this is sdrawkcab (backwards) that we are all focused on COAL rather than seated depth to really regulate pressure?
Is there a standard seated depth that we should be focusing on in conjunction with COL?
Shouldn't this be the one single thing that determines pressure? As long as the completed round functions in all of your guns it really does't matter what the COAL is. The COAL then becomes secondary.
Just thinking out loud here and hoping someone can explain this to me.
