rear sight out of plumb

[Lumpy Grits]

One other thing.
Make sure you can slide a dollar bill between the back of the forearm and the front of your rec'r.
Double check your firing pin(take it out of the block)to be sure it's not broken. The FP is the most common part to break on '74s, followed by the lever spring.
I have broken many of both.....

If your rifle is capable of 2" grouping @ 100 yds, read that as MOA rifle, then 4" @ 200 yds is possible. Then again, it's possible your rifle/load is NOT a MOA combination. Whereupon, even a "slight" breeze/windy condition can appear to scatter you bullet-holes around.

Also, the wind conditions at the muzzle of the rifle may not be the same @ 200,300, 400 yds. downrange.

Just tryin' to add something here. I do not know it all!

Jim, 2" group @ 100yds =2MOA
I still think the front sight got bumped somehow.
One other thing to check, is the muzzle crown under some strong 'glass'. To see if it got marred somehow.

here is how I checked tang site for plumb

1st I leveled barrel from chamber to front site
2nd I placed a level on barrel perpendicular aka cross ways
3rd I hung a plumb line about 24 feet from rear tang sight
with tang sight bottomed out I positioned it on plumb string and proceeded to raise rear sight
I did this 3 times on Saturday and once on Sunday morning and rear tang sight appears to be plumb with the barrel

from the bench firing at 100 yards with windage set on "zero" I fired 2 groups of 10, these groups averaged 1.9" to the right of center of bullseye

I then fired 2 groups of 10 at 200 yards, these groups averaged 6.9" to the right of bullseye

there was a very light incoming wind at about 10:30 at a maximum of 2-3mph, wind was so light that tree limbs were not moving and you had to look at tall grass to see if it was even blowing

my question is this, if the rear sight is plumb shouldn't the 200 yard groups be only 4" to the right of center if all conditions stayed the same

Chaney the velocity loss at 100- 200 is more than 0-100 the slower the velocity the more the drift because the time of flight has increased so the wind has pushed on it longer. You asked. bobw

thanks bobw, I am learning more and more, sometimes it gets difficult for me simply I am early into my 3rd year of this sport, the learning curve is more than I ever imagined but truly a "fun learning curve

the dollar bill will not slide, "do I sand away some of the wood?"

yes, the screws are snug but not tight

[Lumpy Grits]

Loosen the forearm screws 1 full turn and push the forearm towards the muzzle. While pushing on the forearm, retighten screws and check clearance again.
If needed, sand forearm to give clearance and reseal the wood.
After next range visit, check clearance again.....

I was able to clear a $2.00 bill LG when I was finished, might have sanded a little to much but she still looks good to me, sunshine and 54 degrees tomorrow, I will post results once I have finished sending them down range

[Lumpy Grits]

Put a wind flag at the target and where your shooting from.

sent 10@100 yds down range, good tight group about 2", center of group was 2.5" to right of center

sent 10@200 yds down range, jerked on a couple, other 8 was about 4", center of group 6" to the right of center

100 yd group wind was out going at 8:30 @ 2-3 mph

200 yd group wind changed and finally was incoming at 1:30 @ 2-4 mph

I guess its time to move the front sight

[Lumpy Grits]

Shoot it at 200yds before you move it.
