44mag to hot load?

While going through my ammo stock and cleaning it up I noticed this. About 15 years ago I loaded 4 boxes of 44 Mag. 240gr cast SWC with 17gr Blue Dot. At the time my data said 18.5 was max, now Lyman list 15.5 as max. Did they make the powder hotter or the data more conservative or was the 18.5 a typo? :confused:
My question is what do I do with it ? I hate to have to pull all 200 rds. Any comment, other than don’t load more than you shoot, would be appreciated.

I quit using use Blue Dot for handgun loads in the late '70,s. It still came in the cardboard foil covered packaging then. I loaded some .357 Magnum rounds that I had been loading for about a year. The only different component in the load was New .357 Mag Winchester Nickel Cases. No problem, right? WRONG. The substitution of that one item caused a pressure spike that split each case open lengthwise, and I had to use a pall peen hammer to gently tap the cases out of the cylinder of my Colt Trooper.
I beleive there are MANY other powers available today more specifically developed for handgun use. There's really no need to use a recipe substitution, (shotgun powder in handgun loads).
As for your .44 Loads, better safe than sorry.
