45 acp shooting high?

[randyrat]

Whats up with shooting this high....8" at 50 feet... I have a great load and i have to aim 8" low to keep from blowing the targret holder off.
Its a 195 grain(200 gr mold)SWC TL design 4.5 grs of 700X......Do i have to go back to a 230 gr bullet. I'm shooting a Witness 45 4.5" barrel.... I's the best grouping bullet i have had yet and it shoots too high. No sight adjustment.

I Thunk you need adjustable sights or Load to factory to specks.Your sights maybe set for a factory velocity.. Mignt be wrong somebody else might know more ..

[mpmarty]

to incrementally lower the POI, incrementally increase the powder charge or boolit weight.

My Witness pistols all came from the factory dead on with factory equivalent loads so I guess you might try 230gr at 850fps.

[Joni Lynn]

Usually in a handgun a lighter bullet shoots lower due to the amount of time the bullet is in the barrel (barrel dwell time) and will also shoot lower if the velocity is increased. Slower and/or heavier bullets will shoot higher.
If nothing else works a shorter rear sight or taller front might help out.

[303Guy]

It's like Joni Lynn says. Also, at too low a velocity the barrel could be beginning to unlock before the boolit exits the muzzle, tipping it up even further.

Typically heavier bullets shoot higher.
Slower bullets shoot higher.
Slow and heavy bullets shoot a lot higher.
It does not seem to add up that 195 gn boolits would shoot higher than 230s unless the velocity is somewhat lower.
Just putting a lighter boolit with the same powder charge will not automatically give higher or even equal velocity.
A chronograph is worth every penny as much as having a scale is.

I would try a 230gr boolit... I own two witness .45's, and they both LOVE the TL 230 round nose, over 4.3 700x...One will shoot a ragged hole at about 15 yards with this combo. The front sight is cast into the slide, but I know some people have soldered beads on the sight, to raise it, and Meggar made an adjustable rear sight for the witness.

A few years back. I bought one from CDNN investments for about 20.00 bucks....

Ill go with the cronograph being worth every cent. My Rem model 48 shotgun shoots 12 inches high at 30 yards with slugs but is dead on with shot. The barrel also recoils and moves upward on this gun. 303guy may have this one right.

If you have fixed sights the front sight is too low My 45 acp shoots too low Had to cut the front sight down Rick

It's all been addressed here.

Trim the front sight, adjust powder charge, or go with a lighter boolit.

Could the installation of adjustable sights be an option??

I have a long ways to go with velocity on this load and i could put an adjustable site on it also.
I'm at 4.5 grains of 700X and i could possibly go up to 5.5. I just wanted a nice N easy load with the 200 grainer bullet. It just happened to be the sweet spot for that bullet, powder (4.5 grains of 700X) and this gun.
I also bought a sheeeeet load of this stuff real cheap so I was determind to find a load using this powder.

I'm sure you meant to say the opposite:D Gun shoots high, raise front sight to lower POI.

The OP may want to install a higher front sight and an adjustable rear.

My 45 D.W. CBOB shot high with lead 200 gr SWC bullets and 230gr WWB so I went from a front sight that was .140" high to a Dawson F.O. front sight that was .180" and it shoots where I want it now. I was shooting around 1.5" high at 7 yards and just shy of 3.00" high at 15 yards before the change.

[HeavyMetal]

As I see the choices are simple adjust powder charge t get mre velocity and hope the sweet spot stays or instal adjustable sights and continue with the load you like.

I'd bump up tp 5 grains and see what happens. 700X has always struck me as a wierd powder and I'll bet you'll find a load between 4.9 and 5.3 that will get you what you want

[randyrat]

That would be nice if there is another sweet spot
