BigFiveJackWW Gun Powder - As Referred To In The A-Square Manuel In The 458 LOTT Section
What is the full name of this powder,
[WW] and is the company still operational?
I ask because of very low, [comparitively] PSI pressure readings recorded with it's use.

GrandpasezOlin(Winchester powders)- WW748, WW760,
are examples. Military surplus by OLin has
WC in front. Like WC- 872, WC- 870, WC -860....Mostly doublebase ball.All good
for getting best velocity at lowest
peak pressures.Ed-
