The gun that you have shown is a very Early Model 66. The early Model 66's had the flash chrome rear sights as well as their Hammer & Trigger. They Only has those features for about a Year when S&W started Bluing the rear sight assembly and the hammer & Trigger were color case Hardened. so I would say that your gun was made in 1970 time span and a very rare revolver to find.
If you open the gun's cylinder it should have a stamp of "MOD. 66"
In the lower left hand corner of the frame directly in line with The extractor rod cut out that will be stamped directly into the Gun's forward portion of the frame area. I would say that if your gun is shooting high it could be a couple of thing's effecting it's P.O.I.
I would first see if the Rear sight assembly screw's are Tight
. These will be the two screw's in the top of the rear sight assembly where it is attached to The Top strap of the revolver & It is Not uncommon
for the two rear sight screw's to Loosen over time due to the High recoil of the .357 Magnum cartridge in a Medium weight & frame gun.
The second thought I have is Bullet weight
. Typically when a Bullet's P.O.I. on a Target is High it can be corrected by shooting a Lighter weight Bullet. Anotherward's if you are now shooting Factory load's
with a bullet weight of 158 Grains
which is the Most common bullet weight for the .357 magnum cartridge I would suggest that you try a Lighter weight bullet
. I do know in factory load's you can get Bullet's of Lighter weight's being 110 & 125
. I would caution you to Not use of these Lighter weight bullet's Too often as they are known to crack the forcing cone
in these K-framed revolvers. if you are shooting Re-load's I would try and adjust the Power dispersment some
Meanig Lees powder for the load's being shot to see if that help's with your Trajectory issues. I hope this helps, Hammerdown
