You said 'testing'. For handguns, I expect some degree of accuracy at 25 or 50 yards. Seven yards is too short a distance to determine 'accuracy'. One may never need a shot at 50 yards, but an accurate load at 50 yards will certainly be more than adequate at 7 yards.
Now, if this is a self-defense load and you anticipate no distances further than seven yards, why bother with accuracy testing at all? Most any load will impact close to sights at seven yards, so I would simply develop the most powerful load that will:
1. Operate reliably in the firearm in question,
2. Allow safe and positive control of firearm in question, and
3. Meet any legal conditions or restrictions you may face.
Other than that, for what other purpose do you load? If you're developing a load for bullseye pistol shooting, obviously it has to group well at 50 yards. If it's a hunting load, it has to deliver at whatever ranges you anticipate shooting your game.
