I've only used Unique, Herco and Titegroup so far.
In my cowboy action days, seemed Titegroup had more flash than the others. Some liked it because it wasn’t position sensitive.
In a partially filled case Titegroup performed the same no matter if the charge was at the front or rear of the ctg. Its said others not so much. I don’t know. Just repeating what I’d heard.
Your Titegroup experience?
