9.3x62mm Mauser Rear Sight

[WebleyGreene455]

Hi everyone.

I'm wanting to start working on a 9.3x62mm Mauser as a sort of medium-long-term project. I want to use a Kar98k/military-style tangent rear sight on this rifle, but I can't find one and don't really know where else to look. Obviously a sight designed for 8mm Mauser won't work with a 9.3mm, so I can't just put an Kar98k sight assembly on the rifle.

Does anyone know of someplace I could find such a sight assembly, or someone who could produce or modify one or otherwise help me with this project?

Thanks,
W.G.455

Would a 7x57 sight calibrated for the round nose 173 grain be close enough. A guy could compare ballistic coefficients and get pretty close.

Most 9.3mm I've seen has a much heavier bullet and I was planning to use 258, 286 grain bullets in mine. I'm not sure that a 7x57 sight would work very well with that.

Owning a 9.3x62 I'm wondering how far you are planning on shooting with it? It is not a great long range round and surely you aren't going to hunt with it much more than 200 yds?

The 175 gr 7x57 should be very close in trajectory to the 286 gr 9.3x62. I shoot both of those loads extensively. The BC’s are very close. If I remember correctly the trajectories of my reloads are as follows:

9.3x62: +3”@100, +0.8”@200, -9”@300
7x57: +3”@100, 0.0”@200, -12”@300

I would think irons calibrated to the 7x57 load would be fine out to 250 on the 9.3x62.

I consider both of these 300yd loads with a little Kentucky windage. I hit a jackal running straight away from me at +300 off the sticks this summer with the 9.3. Just the depth of his body over the spine and thump.

I'm thinking about it in meters instead of yards, since I'm sitting here looking at my Kar98k, which has notches in 50m increments up to 1km. Obviously that's vastly out of range for a 9.3mm, but even with, say, 300 or 400m maximum, a 25-meter-increment tangent sight would be fine with me. I've seen those, or similar ones, on vintage rifles before, which is why I've been thinking about one for myself.

Check the Mauser forums and their classified ad boards.

what @WAB said.

If the BC is the same, and the MV is the same, two different bullets fired from two different caliber rifles will have a nearly identical ballistic arc.

I get almost the same trajectory out of 180 gr .308 (BC of about .5) as I get out of 250 gr NAB fired out of my 9.3x62. The 308 is about 75 fps faster at the muzzle. Doesn't matter if you use metric or imperial, the arc is the arc. Set your zero at about 180 meters, and you'll be good to go (without much Kentucky windage) out to about 270 meters.

Have you tried eBay, Gunbroker.com, Armslist.com, Numrich? I teally think eBay and Gunbroker.com are probably the best places to look.

There might be enough parts on Numrich to individually purchase to assemble one, I didn't look in detail.

If it was my 9.3X62mm rifle, and my eyes were like they were at age 18, I'd put a 3 folding leaf rear sight from Sarco on the barrel.

I've looked at Numrich and several other sources for parts. If I decide to go with a 7x57mm rear sight, I should be all set. But I don't really need, or particularly want, one of those. If I could find a sporting tangent sight like I've seen on some vintage rifles, that'd be better, or if an existing sight could be modified, the ramp shaved and the ladder renumbered or something like that I'd be OK with a 7x57 one, but I doubt it would really be worth it in the end.

I'd originally planned to put three-leaf NECG sights on it and I'd probably be better off with those, save the military tangent for a 7mm or 8mm companion rifle.

Take a look at the aperture sight Von Gruff made for one of his Mausers. You may be able to do something similar.

Von Gruff can you supply a photo so we don't have to go looking?

I hadn't given much thought to an aperture, but as long it wasn't in the way of the scope I think I'd be open to the idea.

I think you're going to need to choose one or the other - glass or tangent/aperture, unless you can mount the tangent on the tang.

Here's a 5-shot group from 100 yards with a NECG aperture mounted on my Zastava Mauser. I'd be more than comfortable shooting out to 250 with this set up.

When I say "tangent", I mean a military-style ramp/tangent/ladder sight fitted to the barrel. That or express sights would work fine with a scope. But agreed, an aperture sight would probably get in the way of the scope unless it was attached to the hammer or if it folded and the scope was mounted high enough.

 

[WebleyGreene455]

Aha! I have discovered McLaughlin's Rigby-style bolt-mounted peep/aperture sights after finding a thread on here and I like the look of those very much indeed. But I feel like I'd be apprehensive about securing a sight to a Mauser bolt (specifically to the hammer). Seems like a problem waiting to happen compared to a receiver- or barrel-mounted sight. Can anyone weigh in on the McLaughlin or Rigby-style in general?

@Shootist43 Was that the @Von Gruff rifle you were talking about?

Here is the picture of Von Gruff's solution to a similar situation https://www.africahunting.com/threa...coped-mauser-express-rifle.47434/#post-509252

You will have to scroll down to see Von Gruff's handiwork, but there are other options in this thread that might give you some alternatives.

Very cool sighting system Von Gruff!

The tangent sights on the military rifles were designed as a battle rifle sight, you need to look at the military order of battle and manual of arms for their intended use. The tactics used by soldiers to employ the rifles in warfare vs hunting game with them. The 7x57 and 9.3x62 have about the same trajectory from 50-1000 meters. Out to 300 on game is doable very easily in the hands of a competent riflemen. We have a responsibility to make ethical shots on game to cleanly harvest our game. In warfare you are trying to punch holes in the enemy combatant, and wounding them requires much more logistics (Manpower to evac to medical facilities, care of the wounded vs recovering a dead enemy) so two very different requirements.

You should be able to use the Tangent sights for your 9.3 and there is a good deal of satisfaction in ringing steel at 500+ with iron sights.

Steel and paper are the main reason I'd want the tangent sight. I do like the Rigby-style aperture, though, now I've seen it, so it'll come down between one or the other.

Sorry for the late reply. Yes that is the sight on Von Gruff's rifle that I was referring to. For my money the Rigby Aperture would be the way to go.
