Well, Straightshooten, you discovered the famous MMC Diverter from the 1960's. Had one on my 37 in the Navy. they made 2 to 1 and 4 to 1 ratio devices. they spread #4 military buck either 2 units wide for each 1 unit tall or 4 units for every 1 unit. the muzzle end resembled a figure 8. I also saw some home made ones at Cat Lo, never shot one of those. They were very effective for shooting into dense vegetation and night shooting. Problem is that you still needed 10 to 12 feet for the pattern to spread.

If you really are sold on spreading your pattern there is a product called square shot available in the LE circles, it will do what you want.

I do ask you to consider shot density and all the good thing that does for you before you set you sights on this option.
