Good Day,
Shooting to the right of center with Savage 99 30-30 with an old Marbles tang sight without windage adjustments. Rifle is 1927 vintage and a takedown G model. My first tang sight so please cut me a break on this question. As I am hitting right, which side of the Marbles gets the shim?
Thanks a lot

Assuming the front sight is integral drifting the front sight it is not an option.
In general shimming is more for vertical adjustment than windage and done on scope mounts.
I supposed you could try to shim the right side of a tang sight, but depending upon just how far off right it shoots it may not be nearly enough.
A better solution would be for you to try your "second" tang sight that has windage adjustments.
There are $50-75 options that'll do the job. Williams, Redfied, Lyman all made receiver sights that utilize the tang mount holes.
Might even be some members here that have one available. ??

Shimming the tang sight has its limitations, as stated by my erstwhile companion. Worth a shot though. Put it under the right side of the base to move impact to the left. Be aware that you won't be moving the sight in a linear direction, rather in a slight arc as you tilt it. Elevation will have to be fiddled with too when shimming. It can be a frustrating venture, if fine pinpoint tuning is the goal.

Assuming a blade front sight that's non-windage adjustable, you can gently tweak (bend) it also but that's a troubling solution and would bug me every time I looked at it. Still in all though, form follows function, no?

Best bet: Lyman 30 1/2 or 29 1/2, or Lyman 103 (if your last name is on a Swiss bank account).

I thought mid-20's G's had front sights dovetailed into a ramp?

Murray says 1928.
I have 291xxx/1926 - integral
301xxx/1927 - ramp

Ahh, gotcha. I should live my life with my Murray in my hip pocket. That or memorize the bloody thing once and for all!

if you handload trying different powders and or bullets can move your poi around.

If it's only an inch or two off I wouldn't sweat it, and take it out and shoot stuff with it.

I’m with gnoahhh. I’d put a narrow strip of shim stock under the right side of the tang sight to cant it slightly to the left.

I had a similar problem with a tang mounted peep on a Remington Model 141 pump gun. Cut a couple of strips out of an empty soda can and put two of them under the right side of the sight base. For me, that was enough.

You don't say how far you're off to the right, so you'll need to do some math. Basically, you want to move the center of the hole in the peep (not the base) to the left in the same proportion to the front sight as the bullet strike is to the right at the range you are shooting. So, if your sight radius were 36 inches (1 yard) and you were 10 inches to the right at 100 yards, you'd want to move the center of the peep 0.1 inches to the left. You'll have to experiment with the shims to see how much each thickness moves the sight.

Get it within 2 inches or so to either side and call it good. You're shooting at minute of deer, so anything that puts a bullet into a basketball sized ring will hit the kill zone.

Thanks All,
It is hitting about 2 inches to the right of center at 50 yards. Only tried Hornady 150 grainer factory loads so far. I will experiment with some handloads and try a little shimming on the right per your suggestions.
Appreciate your help as always.
