JS, = "experiment by reducing the OAL by .01" increments ... "

That sounds like quite a bit, especially at (if) a max load. In many instances, just a .005" change can improve accuracy - towards or away from the lead.

I would suggest that if you are going to change seating depth by .01", I'd back off at least 5% max & work back up - safety first & all.

Many times you can't seat bullets out to optimum length as the magazine won't allow the longer OAL ....

If you can, I'd recommend start working up your load with the bullet about .005" off the lead. This allows the bullet somewhat of a runing start, while seating hard up against the lead can boost pressures rather quickly.
