Trap 100 in Handgun Reloads

RCrosby

I was pawing through my powder inventory this morning and discovered a can of H. Trap 100. Labeled as "shotgun/handgun" powder. I've checked half a dozen manuals and found no listings for this powder in .357 Mag.
Has anyone used T-100 in .45 ACP, .38 Special, .357 Mag., .44 Special or .44 Mag?
Think I'll check out the Hodgdon site now. Should have done that first, but since I've already typed this much, I'll let it stand.
Thanks,

It's probably too fast for any but much-reduced loads in 357. It's also been discontinued long enough that there won't be many (if any) references to it in current data.

In handgun loads, however, you can use RedDot data and compare the velocity you get with what a Start RedDot load would give, and adjust from there.

Added: I just looked it up. Trap 100 is very close to 700X, and right between Red and Green Dot. Follow the advice I gave above, and you'll be fine.

I used 700-x for years for reloading shotshells and now use it for 44special and 44 magnum reloads. It seems most loads that I've found were for the larger capacity pistol cartridges.
