Scope Rail-Mauser Yugo 98 22-250

  • Yep, they make them. Also for the longer 98 actions as well. The big question is your receiver drilled to match their hole spacing or do you have to go with a blank and have it drilled by a gunsmith? Yes and no. I bought a Farrell rail on a chance it would work on my 308 long action Turkish Mauser and it matched perfectly. The reason it did is because I originally had a Redfield one piece base installed and it shared the same screw pattern as Farrell's with the exception of an extra mounting hole in the rear of the Farrell base. I used it for several years without ever drilling and tapping the receiver for the extra hole and finally had it done when I had the barrel threaded for a suppressor. I don't think I just got lucky on that one I am pretty sure they designed it that way. Farrell isn't the only manufacturer of rails for Mauser's and I recently picked up two made by EGW for a couple of Yugo Mauser's I have. They are aluminum and not too pricey and not near as heavy as a Farrell. The one I tackled yesterday I knew was going to be a problem but I have something that will work but maybe not the best solution. The real way to do this one is with a blank and have it drilled. We'll call this southern engineering. You can see in the pictures this rifle has a two piece Redfield scope mount. The front holes in my receiver were the same spacing as the mount I bought but the back ones were not even close. I knew this when I ordered the rail and expected trouble so instead of altering the rifle I altered the rail. I ended up plugging the rear hole in the mount and drilling a new hole and counter bore centering the tapped hole in the receiver. Like I said southern engineering. It's a three screw set up and four would be better so it's obvious a blank would be the way to go. I had to do this in a drill press so I took a little shortcut. We'll see how it works. Farrell recommends bedding these rails to the receiver but I never did my 308. I have another Yugo that luckily has a Redfield one piece base and with any luck the EGW rail will sit right on it and attach in the existing holes minus one in the rear. In hindsight I believe I could have used along action base for this particular rifle and utilized the second rearward hole in the receiver. If I had a milling machine I would do it right. If.......If frogs could fly they wouldn't have a sore ass.

  • Well, I did the second one yesterday and it wasn't exactly a plug and play kind of thing. It had a Redfield/Leupold one piece base like most of the Mauser rifles I have that employ three mounting screws. The hole centering was the same with the exception of the rear hole and a little tweeking with a small round file fixed that. A pass through with a slightly larger bit for the through hole would have worked also. The problem was the stripper clip hump on the receiver. Some people grind all that garbage off when they use a military Mauser action and some leave it there, like me. Lazy. EGW designed these rails to be placed on the receiver with the leading edge .250 rearward of the front receiver ring so the mount clears the hump and you can do a four hole mount. That's what you want. I don't remember if I did the original drill and tap on this rifle or my buddy Dwight that did the barrel fitting and bolt forging but anyway it was too far forward and the rail hit the hump and only one hole could be used. Bummer. There is a couple of ways to drill and tap a Mauser receiver for either the Redfield type or the rails and I have done both. One is by measurement hopefully in a milling machine with a nice read out and a Kurt vice and snap jaws with built in parallels and the other is a fixture. The fixture can be used with a hand drill, yeah right. Or with a drill press. The only catch is the barrel has to be out of the action. I have done a couple with it and it wasn't any fun. I rigged up a vise in my drill press to mill this rail out so it would clear the hump and it worked. Just took a few minutes more and only have one screw in the rear of the rail however it's a hunting rifle and I don't see how it could fail. Happy Fourth.

  • @bigfoot I mounted the Schmidt Bender scope on the 22-250 last year and pulled it out two days ago to shoot it. It shot six inches low after I bore sighted it and ran out of elevation at four inches below the bull at 100 yards. Installed on the rail sets the scope up pretty high above the bore and it is a zero cant mount. To my eyes it looks pretty level maybe a 20 moa rail would fix it but for now I scrapped this set up. It could possibly be slightly inclined. Might find a scope with more elevation adjustment or go back to Redfield rings. Of course I referred to the scope manual after the fact and this particular model has very little adjustment both elevation and windage. The ranging dots were established for this scope taking the average trajectory drops from typical varmint cartridges and range from 1.1 moa to 11.24 at the fifth dot below center. I shot some 55 grain spire points and some 40 grain V Max just for the heck of it before I broke it down. Now it's sitting on a CZ 527 .223 maybe it will adjust at 100 yards.

  • @bigfoot Had some success today. I set up the portable bench and shot a few rounds at a target today. I have some 55 grain PMC full metal jacket .223 I keep for my ar's but no handloads or a better grade of ammo for target work. I just set the scope on the CZ and didn't touch the dials and it shot high six inches and right about three at 100 yards. I'm not 100% sure the model of this scope according to the manual the click values could be .200 inch or .280 inch per click at 100 yards. Anyway my first adjustment was 24 clicks down and 12 left and I still wasn't there so maybe the clicks are .200. I finally got it adjusted pretty close to center going four clicks at a time. The elevation is marked H and T, H being up and T being down L and R are the same L being left and so on. I haven't messed with this scope very much since I bought it. I settled down and shot a three shot group that's about one inch. Maybe I can do better with some handloads. I pulled out some new Federal Gold Medal Match brass and some Berger 55's and with any luck tomorrow I will load a few.

  • @bigfoot Hoch is German for High
    Tieff means Low
    Links means Left
    Rechts means Right

    German convention is that you describe the POI and dial accordingly. If that’s confusing, move the top of the turret toward the goal as if they are right hand threaded bolts.

    Anschutz iron sights adjust the same way. Clicks are usually 1 cm at 100 m or .5 cm in some cases.

  • @rr2241tx Thanks for the German lesson. I unscrewed the caps and thought about it for a minute and then just went to twisting. The old dead guy as you called him had a big collection of Schmidt's if you remember. I almost bought one of the lower variable power scopes that had the ring with with the + in the center that were illuminated he had. I think Don had five of them new in the box. No parallax adjustment they would have made a good scope for hunting. These Long Range Klassic scopes must have been a limited run I couldn't find them listed anywhere. Old dude had several of them new in the box and after some horse trading with Don I got one. There was two copies of instructions for use of the reticle in the box as well as the multi language manual I finally read. I was just anxious to get going and wasted a little time is all. The dilemma with the Mauser is finding a two piece Redfield base in 30mm or a 20moa rail and doing the machine work to fit it. That's just too much for too little I'll just put a 1" scope back on the old base and call it good. I had a Nikon on it that zeroed perfectly and had a BDC reticle that came with a ballistic program I can access for holdover values. I looked at a Huskema 1" scope or something like that in Pearsall this week that looked like a fair scope. It was quite a bit more than a Nikon though. Now if I can just find the base and rings I took off. :/

  • @bigfoot The sight in target with PMC fmj. I saw this exact same ammunition yesterday at Los Cazadores store for twenty bucks a box. Pretty sure I paid less than eight for case quantities but that was then this is now. A bunch of adjusting on the scope and I finally settled down and shot three in the lower right hand corner. I started with a squeaky clean barrel so it might have just took some fouling.
