If it is 296 then there should be an Orange Band with a large 296 in it. In smaller font above it should say:
"For Center Fire Rifle, Handgun, and 410 Shotshell Loads"
There should also be a 2963 on the lable to indicate W296 3 lb. can.
WAP: Winchester Action Pistol was introduced in 1994 and was made to replicate the powder used in factory 9mm and 40 S&W loads.
WAP3 means Winchester Action Pistol 3 lb. can.
If you have the Orange Label with 296 in it and WAP3 in small print at the bottom near the Net WT marking then something is a misprint. As the Staff have said, post pictures.
Underloading 296 poses one issue; overloading WAP presents another.
