Best over the counter buckshot

[RMc]

Which over the counter buckshot loads will deliver the best pattern? Well, all shotguns tend to be a law unto themselves but in general those loads with buffer and a shotcup pattern better than those without. Hard shot or plated shot certainly helps.
 
Here is a quick list of over the counter 12 gauge buckshot loads put up with buffer and a full length shot cup.
 
Federal Premium with Flite-Control Wad - 00 buck only.
 
Federal Premium buckshot - all shot sizes (except 3.5" loads-partial shot cup)
 
Federal "regular" buckshot - all shot sizes
 
Winchester Super-X #1 Buckshot 2.75 and 3 inch loads. This is a low cost 'sleeper' load and is among the first to sell out locally. All other WW buckshot, including Supreme loads do not have a shot cup.
 
Remington Express 9 pellet OO buckshot round.
 
Remington Low-Recoil 8 pellet 00
 
The 3.5" 18 pellet Remington round uses the same shot cup as the 9 pellet load and has 8 pellets exposed to bore scrub. All other buckshot loads from Big Green lack a shot cup
 
Hornady Buckshot - 8 pellet 00
 
There are a lot of buckshot rounds on the market that have fiber wads and buffer but nothing to protect the pellets from pellet flattening bore scrub. Some of the foreign made buckshot rounds, like Wolf brand loads, don't even have buffer.
 
This list does not take into account Buckshot marketed to police. Nor does it include innovative loads from small independent firms like Dixie Slugs - Tri-Ball 3x.60 Buckshot round.
