Will a handgun load developed at 10 yards perform just as well at 25?

Regarding the inherent accuracy of a particular load... Would a load that performs well at 10 yards perform just as well at 25 with only the shooter's skills having any effect on group size?

Assuming good ESs and SDs--consistent velocity, IOW--yes. The group will probably be bigger, however.

Shooting skills, at those ranges would be the deterinining factor...unless the weapon had to be aimed like a mortar, due to light loading...:D

Why dont you do an experimant and test this out. Then you can report on the forum.

If you can keep them all in a single .45 inch hole at 10 yards, I doubt if you can at 25 yds.

At those ranges, the angular dispersion should be consistant.

If the velocities are way off, the shots might spread out vertically at longer range since the slower bullets have more time to drop. There are also some weird things that happen if the bullet goes from super- to sub-sonic between 10 and 25 yards. If the bullets are tumbling once they leave the barrel, then the effect gets worse the longer the bullet is flying too. I guess these are pretty odd situations, though, and probably don't matter unless you've got a real tack driver in a solid benchrest. Maybe the rule would be that really crappy loads are even crappier at range?

The shooter's skill won't matter, once the bullet leaves the gun it does it's own thing if it goes 10 yards or 1000. You're just as good or as bad a shot no matter how far away the target is, although your brain starts messing with you when the target is way down range.

One thing to keep in mind is that at 10 yards you might not notice accuracy problems that you can see more easily at 25.

Exactly. For example, if someone has a 1" group at 10 yards, expect that same load to group at 2.5" for 25 yards, not 1".
