For targets inside of 25 yards, does anyone use a negative five spreader? The term diffusion choke is an oxymoron, but was wondering if anyone has patterned one and compared to a cylinder or skeet choke?

I have 2 LNIB - Browning Midas grade - Invector Plus - Diffusion chokes for sale. They have been used but remain in almost new condition. $100.00 Shipped bubbajack
