Title: Shooting High
Post by: Pappy Hayes on February 26, 2012, 02:38:05 PM
I have a Pietta 58 Remington with a Kirst conversion cylinder 45lc. Shooting at 25 feet it shoots high. I have a good pattern but high. Is it me, or something else. Others have shot it with usually the same results.

Bullet weight and velocity will affect this. Try a lighter bullet or more "potent" load. And Pappy, "pattern" is bad, "grouping" is good ::)

Velocity changes are neutralized as "barrel time" and "jump" counter each other

It is bullet weight changes that largely affect POI. 

Heavy = high
Light = low

As a cap'n baller is usually sighted for roundball, which is much lighter than most bullets, the heavy bullet will strike higher.  The fix is to change the sighting, or go to a lighter bullet like DDs EP-UGG or the Slim.

Well OK, I'll agree if we are talking 50 or 100 FPS but try shooting 44 Special and 44 Magnum with the same bullet weight and sight setting..........(or 38 and 357, or well regular loads compared to cowboy wimp loads)............. :-\

By the way I have 8 or 10 Remington conversions and they all shoot like a 6 o'clock hold when I hold dead on with standard 45 Colt loadings with 250 grain bullets (this means they are maybe 4 inches high at 25 feet).

When I hold on the bullseye my gun hits the next to the last and last ring. Not sure the exact size of the target. It is one of those that is black with green lines and leaves green around the hole. I would say it is about a 4x4 at a guess.

Pappy you say you are aiming at the center of a 4x4 bull. And that you are hitting in the outer ring......

This means that you are hitting approximately 2 inches higher than point of aim (POA).
If you hold at the bottom of the bull (what we refer to as a "six o'clock hold") you would therefore hit in the center of the bull.

This is pretty decent and NORMAL for what you are doing and for what you are shooting.
Bullets travel in an arc and at some, not so distant, point the bullet impact will be right on POA again.
If you take all of this into consideration you should find this acceptable and a "six o'clock hold" is much faster for the speed sports.

The simplest explanation is usually sufficient.
