Steve,
What manual do your loads come from?
I suspect that these are loads you have worked up in your guns.
If you are going to list loads please list your sources and / or a disclaimer that the loads you are recommending may exceed SAAMI maximum pressures and should be checked against reliable sources.
5 of my 9 manuals all list 23.8 to 24.2 as maximum load with a 240 grain jacketed bullet and 3 of those five list it at 24.0 as the maximum load.
Hodgdon, Lyman, Sierra, Speer, Hornady
I have been listing my loads here for over 4 years, and have never had to qualify or justify them. It has been understood that all loads I list are NOT from any manual but from my personal experience.
As the disclaimer states on my reloading data pages:
"
Number One:
The information and data contained on the reloading pages is for informational purposes only. I do NOT assume, nor do I accept ANY responsibility, implied or expressed, for the accuracy of the material posted, nor do I assume or accept ANY liability or responsibility, implied or expressed, of the results you will obtain by using any of the data posted on these pages.
I have no control over variations in components, reloading tools or your procedures. YOU are solely responsible for EVERYTHING that may occur using this data.
Number Two:
The information listed for MAXIMUM loads may be safe only in modern firearms of current manufacture and in excellent condition! The age and condition of YOUR firearm is the determining factor! NEVER, EVER, START WITH ANY OF THE MAXIMUM LOADS!!!
Number Three:
Always start out with the lightest powder load listed and work up GRADUALLY until signs of case failure or excessive pressure become evident! Or until the level of performance you desire is reached. WHICHEVER COMES FIRST!!
Number Four:
The data contained herein is NOT bounded by SAAMI limitations! Because of this fact, be ABSOLUTELY sure you understand numbers one, two and three above!!
The highlighted powder in the selection area is NOT sacred, truth, fact nor absolute. It is the powder and primer combination I chose as best when I was reloading that caliber, with that bullet. It is based on three simple facts:
1) A "gut feeling";
2) Almost 50 years of experience;
3) They worked just fine in the firearm I was testing.
Number Five:
The data contained here is for copper-jacketed with lead-core bullets. It can be used with lead bullets and solid bullets (but YOU must take into consideration the composition and construction of the bullet). It is not designed to be used with coated bullets of any type. If you are intent on using coated bullets, buy yourself the reloading manual published by the bullet manufacturer!"
And, on a personal level, I do not appreciate the public chastisement...
