Powders being 'outdated' is a screwy concept...
came into some pull down pre WW 2 vintage IMR 4895, from ammo I disassembled.. dates on the cases were from 1936 to 1941...
tested it out in a 22.250, and compared it to current production IMR 4895....
The 1930s stuff actually shot tighter groups...
if 3031 shot well and performed well in any cartridge you want to choose say from the 1930s or 1950s.. why would it be thought that it would perform differently in the same cartridge currently....
a 30/30 is a 30/30 still, just like an 06 still is an 06, etc...
some think, a newly released powder has to be better than older powders, or they wouldn't have released it...
that is what I refer to as what is currently "trendy" and what isn't...
I'm told on this site that RL 7 isn't a good powder for a 22.250 for example...
yet I still find plenty of data around for it... and it will still perform just fine with highly usable velocity, with bullet weights from 55 grains on down in that cartridge...and gives some of the fastest velocities I have seen with light bullets, same in the 223...
too many folks think if a powder won't yield the fastest velocity possible in a cartridge, then it is either 'obsolete' or its " too fast" to use in that cartridge...
