No problem with either in my experience with an 11-87.
Depends on your definition of quickly 
In theory, heavier shells, whether slugs, buck or shot, will clog gas systems faster because the slower powders used for heavier rounds leave greater amounts of unburned powder and residue. Take a peak down your barrel after firing magnum loads compared to target rounds.
In practice, it would take hundreds of rounds to get to the point where this would reduce functioning. I've owned both an 11/87 and Beretta 390 up for slugs and buck and neither ever jammed due to clogged gas ports. The guns were kept lubricated but not always cleaned as diligently as they should have.
