Ok Nutz, here be the results of my second range test of my Rossi .357 Mag.
Ranch Hand Baby Carbine. I used the same load as the one in my first test.
(158 gr. LSWC hard cast bullet ahead of 12.0 gr. IMR 4227 powder.)
Velocity is right around 1200 fps.
The first target was shot with the .538" high Marbles front sight in combination
with the Marbles long shank Bullseye rear at 25 yds. The rear sight was set at the
lowest notch in the elevator.
As you can see, this particular sight setup put the shots at the correct
height for a six-o-clock hold on the bull. The dropped shot was caused by
my eye floater gettin' in the way as I touched off the third shot.
This pic shows how the sights look together on the rifle.
As I figured earlier, the .538" height sight would get me in the ballpark
on this gun.
Next up was the Marbles long shank Flat Top rear sight in conjuntion
with the same .538" front sight. This particular sight tapped into the
dovetail with less resistance than the Bullseye sight but it's easily
corrected for fit using Loctite 541 hydraulic sealant.
I fired this group by covering the target center with the front bead.
This setup also put my shots into the ballpark as well.
As I stated in an earlier post, the .570" high front sight would be too high on these guns.
Heres how this set looks on the gun. The Flat Top sight looks quite low
compared to the front sight, but it worked ok.
The blue tape was used to reference the position of the Bullseye sight
when I tapped it back into the dovetail. This sight is my keeper.
So there you have it. 2 rear sights that work on Rossi Ranch Hands to
get you on target at 25 yds. in the lowest setting using a .538" high
front sight. This should get you into the ballpark with the .44 mag and .45 Colt guns as well.
Happy Tinkering.
