revolver sight in help

Hey guys, I have a question about my revolver pattern. I have a ruger 357 gp100 match champion with fixed sights and it is dead on at 5 yards but the group slowly rises the farther I shoot. At 25 yards it is shooting about 6" high. Is there anything I can do about it? Im just shooting store bought ammo 38 special. Thanks!
 
Yeah I was just wondering if I could do anything with the bullets to make it dead on the whole way out from 5 to 25 yards. Im thinking heavier bullet maybe less powder?
 
You can't make it dead on over a wide range like that.
The best thing to do is to get it on at 25 and it will not be far off at closer ranges.

The only way to correct is to change sight blades. You need a taller front sight to bring the POI down to the POA.
 
It's probably sighted in from the factory for .357.
I rented a revolver chambered for .357 at the range that did the same thing - way off with mild .38s, even with the sights adjusted all the way.
The notion that a .357 revolver can be suitable for .38s isn't always true.
It very much depends on the ammo selected.
 
That's totally dependent on target size, and would require a 12" diameter in this case

Yeah, six inch radius, sounds like most of the targets I see used at the range I belong to.

I was just wondering if I could do anything with the bullets to make it dead on the whole way out from 5 to 25 yards.

Not very likely. Go for what hits at an intermediate yardage. Say 15 and your over/under won't be too far off for close in or longer.
 
... it is dead on at 5 yards but the group slowly rises the farther I shoot. At 25 yards it is shooting about 6" high.
That's perfectly normal.

This thread explains what's going on.
Bulls eye, or 6 o'clock?
Bulls eye hold and 6 O'clock hold are the same thing--at least in the way that the terms are commonly used. The 6 O'clock hold is what is commonly used for bulls eye shooting.

There are three typical point of aim/point of impact sighting strategies.
  • 6 O'clock hold or Bulls eye hold. Sights are aligned with the top of the front sight at the 6 O'clock point on the bulls eye.
  • Point of aim=point of impact in which the bullet typically impacts directly on top of the front sight at the distance for which the firearm is zeroed.
  • Bullet impacts behind the front sight--some call this a combat sight picture.
Unfortunately, if one is shooting at different ranges to the target, a single handgun will typically shoot all of the point of aim/point of impact strategies listed above depending on the range.

It's not really possible to get a handgun shooting to the same point of impact regardless of distance. Because of the relationship of the bore and the sights, the relationship of the point of aim and point of impact will change based on the range to the target as described in the thread I linked to.
 
Your bullet is not rising. 5 yards is not far enough to see where its actually hitting. At that range your sights can be way off, and you'll still hit the target. Sight it in for 25 yards, and it will still be on at 5 yards. For that matter, sight it in at 50 yards, and it will stay on at all ranges in between.

You point of impact will change with the ammo you use. The higher thd velocity, the lower it will hit. At 5 yards, you won't be able to see the different. At 25 yards, it will be obvious.
