Hey guys and gals and ......
Ok I know there is no rule but I remember reading here about max pressures in manuals can say a lot ... something........nothing
It went something like this , in general the higher the max pressure is for a given specific cartridge/load the more consistent the burn of that specific powder primer etc combo is . ( Talking PSI not CUP or trying to compare them ) Meaning - lets say the Max Allowable Pressure for cartridge A is 30,000psi . The powder that is the closest to that cartridges MAP in the manual is the most consistent and or stable at those max pressures for that cartridge ?
You see it all the time in manuals that powder A max pressure is 29,400psi while powder B max load/pressure is 28,600psi . Why don't all powders have there max load at the MAP of 30,000psi for this example .
I remember there was a general rule about this or an un spoken rule because I know there is no actual rule on this . I got to thinking about this when I started looking up +P loads and found the data and maybe more specific the powder/s available for +P loads seem to be much less then the standard loads . This got me thinking ... because you/they are pushing the pressure limits . You should only be using the most stable and or most forgiving powders in these hotter loads ???
Another reason is that I have many pistol powders from fast to very slow burning and when I look up +p loads I almost never have the powder/s needed for those loads regardless of cartridge .
Anyways I'll leave it there for now , I'm sure this topic will get a few opinions .
Thanks MG
