Not sure what the problem here is & I fly RMS 24mm in my backyard a lot.
What I have learned is that most of my older (5-8 yrs old) reloads exhibit the dreaded "bonus delay" and I almost always drill 2/32" (1/16") out of the delay to reduce all delays by about 2 secs.
They usually work out okay for me that way.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
