This is not meant to be off topic. It does show a problem with any fast powder. One of the traditional target loads for 38 Special is a minimum charge of Bullseye with 148gr. WC bullet. Try to see this charge in 38 Special case in a 550B. Need to go slow loading that one.
Addendum: If I recall correctly two of the oldest power we currently use are Bullseye and Unique. Yes, there have been changes over the years. Years of use may have to do with so many pet loads.
I run a powder check station on my 650 for just this reason. I believe I could triple charged a 45 ACP case with Titegroup and it would not overflowed the empty case. You still got to look and be vigilant but a powder check station is a nice double check.
