K98 Shooting High

[Robk13]

Hello all, I recently acquired a yugo refurbished k98. Has a new yugo barrel and german sights. I took it out last week and noticed at 50 and 100 yards it was shooting high (around 12-14 inches at 100 yards). I shot 198 grain fmj yugo, S&B and some Greek surplus all with the same results.

I measured my front sight at 5mm or .197" I was wondering if anyone else has experienced this and more importantly, how much more material do I need on that front sight to get it shooting to POA? Is there an equation that can be used to determine how hight my front sight needs to be to shift impact down range?

I'd rather not order more than one or two front sights to tinker with as their about 25$ each on eBay (ive seen everything from .187 to .274 in blade height).

I appreciate anyone's advice or experiences with this.

Any help is greatly appreciated.

The sights on my M-48 are dead on for the ranges marked.

The Mods will move this to Rifle Country, I suspect.

I suspect there is a combination of German rear sights and an m24/47 or m48 front sight.
Apologies I wasn't sure where to post this one exactly.

try this calculator: http://www.anycalculator.com/gunsitecalculator.html

I do recommend bedding the action first. I did this on a number or military Mausers. Especially with Yugo's and Russian rebuilds, the stock bedding is horrible. No doubt the action is bowed when you tighten the action screws and the action slides left and right because the recoil lug bedding is not firm. If you bed the action, taking care not to bend it as the epoxy is curing, afterwards you will find the elevation and windage have changed. But the groups will be round or rounder, and stable. And this is the time to fit a new front sight.

The calculator is a guess, it is better to order a taller front sight, for margin. You can always file the thing down.

Foreign military rifles of that era were typically sighted to hit at 300M, figuring that a center mass hold would effectively disable a soldier at closer ranges. Like @Slamfire said, get a couple of the tallest ones and file it down to your liking.

The US 1903 and M1917 rifles had ladder sights that could be adjusted for closer ranges, but when folded down, the battle sights were calibrated for 300 yds.

Buy a higher front sight. Should be a dovetail base. Drive out old sight, New sight may require some filing on the male part of the dovetail. This is not a unique problem with rebuild military rifles.

Good luck

Thanks everyone for the advice, I bought 2 taller front sights off numerich for a swedish mauser. I'll take my file and some ammo to the range when they show up and see what it'll do!

I've used Skinner file to hight. Kinda got carried away on the first one

 

[Robk13]

The Barley corn style Swedish sights should be here tomorrow, I'll be taking them and a hundred or so rounds of yugo m38 ammo to the range on Tuesday. The sights are 7mm (marked +1.5) and 6.5mm (marked +1.0).

I'll follow up after range day and let yall know how it goes!

It's a simple fix. Shoot lighter faster bullets . Recoil starts when the bullet first moves, and the barrel rise is greater with the heavy slow bullets by the time they exit the barrel.

I have regulated lots of drillings and double rifles to custom loads, and this is absolute for sure a reality. That old Greek ammo is awful, IMO. I know first hand of many hang-fires with it.

Use good fresh faster ammo and forget fiddling with sights, trust me.

I do have some turkish light ball ammo, I will try that before I tinker with the sights then and see how it performs.

Let me know your results, please.

Turk is shooting dead on at 100 yards, the
Yugo stuff is dead on if I do a 6 o'clock hold and this rifle is shooting 2 and 3 inch groups at 100 with ammo made in 1940....needless to say I am kind of impressed....I'll keep the +1.5 sight for future endeavors.
