For breaking clay targets just going up in shot size from #7-1/2 to #7 makes a bigger difference than jacking up the speed of lead #7-1/2 shot.

A much slower lead #6 shot load holds it's speed and has more energy at long range than the faster starting smaller lead shot dose.

If you use lead #7 shot or lead #6 shot you don't have to use the extra recoil of faster loads to break clay targets. Any shot sizes bigger than lead #6 shot really lowers the pellet count and lowers the chances of hitting the clay target at real long range.

From KPY Shotshell Ballistics
1400 fps lead #7-1/2 shot gets .60" of gel penetration at 66.9 yards, has .51 lbs of energy and is going 429 fps at 66.9 yards with about 436 pellets in 1-1/4 oz loads.
1300 fps lead #7 shot gets .69" of gel penetration at 66.9 yards, has .62 lbs of energy and is going 436 fps at 66.9 yards with about 374 pellets in 1-1/4 oz loads.
1250 fps lead #6 shot gets .93" of gel penetration at 66.9 yards, has .94 lbs of energy and is going 467 fps at 66.9 yards with about 281 pellets in 1-1/4 oz loads.

Look at how the slower starting lead #7 and lead #6 shot loads are going faster at 66.9 yards than the faster starting lead #7-1/2 shot is going.

About the only thing you gain by shooting real fast small lead shot loads at long range is recoil. If you insist on shooting real fast loads use big enough shot to maintain the higher speed and energy at long range.

The 1250 fps lead #6 shot has 84.31% more energy per pellet than the 1400 fps lead #7-1/2 shot has at 66.9 yards away.

The 1300 fps lead #7 shot has 21.56% more energy per pellet than the 1400 fps lead #7-1/2 shot has at 66.9 yards away.

The softer shooting 1300 fps load of lead #7 shot hits much harder at 66.9 yards than the much harder kicking 1400 fps load of lead #7-1/2 shot.
