Thanks.  This is good data.  I have the first section reformatted as a table below. I will work through the others today.

No problem.  It is a little different, but a feature many forums either don't enable or don't have.  I am going to post a how-to later in the questions/suggestions section.

Hey Thanks, for the data.  I pushed the Hornady 200gr XTP with 10.5 grains of Blue Dot, CCI350, COAL of 1.260" which yieled 1180-1200 fps from my 5" 1006.  This was based off Speer Data with their 200 FMJ testing with the Colt Delta Elite...

Can this be sticky'd.
I will be adding Quickload pressure data to all of the loads listed for the 6" Caspian barrel.

Yes its possible to make it a sticky, perhapse after you have the dada added then sqlbullet, could organize and add it to the nice table (very professional looking) then pin it.  I am sure many would be interested to look at the pressure estimations, I know I would.  Better than working completely blind!

It would be interesting to compare pressures for the 6" to the Glock 4.6" from the QuickLoads software...
The Glock 20 4.6" & Glock 29 is 3.78" barrels are more common so those estimations could benefit some people as well.

Sounds like a plan.  Once the pressure data is posted, I will tablize and preview it, then amend the original post with the data and make it sticky.

Pressures do NOT change with barrel length , the pressure peak happens in 30-60 MS (milliseconds)inside the chamber. This was very eye opening to me.

...the pressure curve happens in 30-60 MS (milliseconds)inside the chamber...
This should be amended to say the pressure peak, which is what I sure you meant.  The curve continues until the bullet has left the barrel and the interior pressure is equalized with local atmosphere.

This I knew.  Once the bullet starts moving the size of the chamber effectively becomes variable, as it is the space between the bottom inside of the case and the base of the bullet.  Since that distance is very small, it grows very fast.  While the powder may continue to burn and produce more volume of gas, it cannot keep up with the increasing volume of the chamber, and so pressure drops as soon as the bullet begins to move and continues to drop unless the bullet becomes stuck in the bore due to an obstruction.

This curve will have the same calculated values at a given point in time after ignition regardless of how much more barrel it must traverse.  All that changes with a different barrel length is the point at which the pressure drops back to local atmosphere.

However, muzzle pressures do change, because the muzzle has moved both spatially in relation to the breech as well as in time in relation to the pressure curve.  The closer to the breech the higher the muzzle pressure will be.  And muzzle blast.

Is peak pressure reached when a bullet first engages rifling in the barrel, or before?
Gun Control?  Oh yes, the theory that becoming a victim is somehow morally superior to defending yourself & your family.  Makes perfect sense.

Every gun is different, but as a general rule if you have a good leade, pressure will not return to the values reached in case. It will spike a little as the rifling is engaged, but usually not the peak.

If the bullet encounters something that halts or seriously retards it's travel (abrupt transition to rifling, for instance) then pressure may spike at that point.  Similarly if you encounter a bore obstruction 15" down the barrel, peak pressure will occur at that point.

At least that is my limited understanding.  I am just beginning my journey into internal ballistics.
