Titegroup can be very dangerous in a progressive press. I don't like the low volume in the case and have double charged a 38 SPL with it.  I was lucky that I was shooting my Ruger Blackhawk in 357 Mag when this happened.  I haven't used it in a progressive since and will only use it single stage like described by @njJoniGuy

I am using a single stage press.

I assume from your comment (some) other powders will call for more, so a double charge would be more noticeable?

Yes, most that I use will overflow when double charged.

But a little bit of Titegroup goes a longgggggggg way.
