I figured out how to "HACK" this website...
Example... I have H-414 powder in my Chargemaster and several DIFFERENT calibers to load...
KNOWING that H-414 powder is an excellent powder for my 9,3x62 Mauser (albeit a TEMPERATURE SENSITIVE POWDER)... I load my 9,3x62 Mauser rounds...
THEN "HACK"
http://www.laddata.se/powder/hodgdon-h414 (by clicking the Hodgdon H414 (blue link) inside the load
http://www.laddata.se/powder/hodgdon-h414This will take me to ALL LOADS that H-414 can do.
IF I LIKE THE DATA FOR ANOTHER CALIBER (.300 WM OR .7MM RM... for example)... I THEN DOUBLE CHECK OTHER RELOADING MANUALS AND TRIPLE VERIFYING IN QUICKLOADS... THEN PROCEED WITH THE NECESSARY LADDERS...
ALWAYS
ALWAYS
ALWAYS work up ladder loads Why do you have to Ladder loads?
I have a .308 load that shoots great in my Remington 700, but is over pressure in an AR-10. Chamber variations and other factors do that.
My pet .300WM loads shoot perfect in my gun, but my friend's gun hates them... he has a different chamber with maybe +/-0.001" or 0.002" headspace variance which will cause my 1/4" MOA loads to be 1 MOA loads in his gun. It may not be a headspace issue at all... it could be that my chamber was cut with an Manson reamer and his was cut with a Clymer reamer... so who knows and who cares... all this detail stuff will make you nuts... just ladder up everything for your gun.
He will have to chase a different Harmonic Node with his ladders. That is just just the way it is!
----------------------------
Why Triple verify loads you find on the web?
Another friend found a load on the web from a so-called expert... Let's call it 55 grains of XYZ powder on a 200 gr. bullet... He backed down that load by 10% (normal starting point on a ladder)
and the starting load (49.5 grains of powder) turned out to be SO HOT that it vaporized the primer and dang near blew up the rifle... SO BE VERY CAREFUL with what you read on the web!
Harmonic node chasing is some very advanced stuff... Research it and ask more question if you like.
Last note: I reverse engineered a few of my pet loads and found a second (and faster Harmonic node) by using something I call "Barrel Time Theory".
Example: My Pet .300WM 168gr BTHP load is KNOWN TO BE super ACCURATE... by reverse engineering it and using "Barrel Time" in Quickloads as the input data... I am able to look at other powders.
Doing this, I was able to find another powder with the exact same "Barrel Time"... BUT, this "other powder" produced far less pressure...
This allowed me to chase the next node... faster speed as the barrel harmonics realigned...
If some computer guy or gal might want to develop such a program... I think you could make some genuine money with it.
*FYI... MANY claim H-414 and W-760 are the same powder... (just like many claim A4100 and Ramshot Enforcer are the same (I NEVER MAKE SUCH CLAIMS... FAR TOO DANGEROUS)), but proceed as you best see fit... in that published data is often identical).
