CZ-858-2 and scope accuracy ...MOA?

No one tried it rested at 100 yards for accuracy report?

From a bench rest I get on average 4" five shot groups at 100 yds using a red dot and Czech ammo, Chinese ammo is not so good. I get the occasional flyer with both the Czech and Chinese ammo.

I think that with a good telescopic scope the groups would be quite a bit smaller, and if hand loads were used it would be really good.
I would say it's a very handy rifle that is well made and does the job it was designed for extreemly well, it was never designed to be a precision sniper rifle, but it is not bad by any means.:)
 
I'm really suprised by my 858, it consistenly shoots 3" or under off the bench open sighted @ 100 yards using czech surplus ammo. I even managed to shoot a 2" group the other day.

I figure a scope will help suck that down at least 1/2" and I'll probably be grouping 2" consistently. It's hard to ask for more out of a com block 7.62x39rifle straight out of the box and 30 year old milsurp ammo :)
 
Where can one find 7.62x39 Lapua ammo in BC? Anyone know of a source?

Does Lapua use Vihtouri powders in their cartridges? I'm thinking it might be possible to reload something really close to Lapua factory ammo.

I wonder if anyone in BC or Western Canada has 123 gr FMJ Lapua bullets in stock....

After reading the post about accuracy by Tudenom and being pissed off as a result I decided to have another go at getting a better group. This time I put a black 3" dot on a brown paper background rather than white so I could see the outline of the red dot perfectly, and managed a group of ONE AND A HALF INCHES !!!. I then removed the sight to see if it held zero when re installed and shot a 2 1/2 " group, the zero was good. I then removed the red dot and tried with the iron sights and got a 6" group, which is as good as it gets as my eyes are well and truly ####ed.

What is needed is a scope. Mykaylo has ordered a POSP, I will wait for a report from him and if his scope is good I will get one myself. The only thing that worries me about these Russian scopes is the price, they seem too cheap, from $88 with built in mount. They certainly look the buisiness though.

Nice shootin' comrades. Let us know what ends up being a good scope setup. I'm sure alot of us would be interested. My eyes are alittle weak too. :(

I have heard people in the US no longer being able to get any lapua X39. But there ammunition is said to get 1 MOA out of the Finish Sako AK so it might be an excellent base to compare off of since milsurp ammo let alone of X39 caliber are usually nowhere near match grade.

The thought entered my mind as well. However, they are Russian military surplus (Belarus factories) so most of them (like our 7.62x39 ammo) are left over from the cold war. Russian labour costs are much less, and this scope can only be mounted on a few types of rifles - so it lowers the demand (and the price). However, without actually having seen the scope this is all my own theory (and my 'brilliant' theories have made me spend pretty stupidly before). I ordered a 4X8X42 version, which is has an AK mount, but I would think is really meant for 7.62X54, and should be mounted on a Dragunov. If you order a fixed 4 power it is meant for 7.62x39 ammo, as the lower chevrons are meant to compensate for bullet drop at 200 and 300 yards. I would have liked my scope to be intended for my actual calibre, but I would rather have the Zoom function, and the larger FOV (the fixed 4x has a 24mm tube - the 4x8 has a 42mm tube - and they're only $35.00 difference in price). I really doubt I'll be doing too much shooting at 300 yards with my CZ - its just not that type of gun. Also, I've just never been a fan of fixed power scopes - I even have a 3X9X40 on my 10/22 (althought its a Tasco Golden Antler el cheapo). I had to order my rail seperately from Kalinka, as they were the only ones who seemed to carry the universal rail. I'm worried that my scope from Belarus will arrive before my mounting rail.

Your theory seems reasonable enough. The only thing that put's me off the big scopes is the weight of them, there always seems to be a downside to most things unfortunately.

I was in town this morning and noticed a metal putty that a store was promoting, it's called LAB METAL, maybe it's the stuff that Ian in vic was talking about. ( www.AlvinProducts.com ) it bonds permanently and is incredibly strong. I think you could just stick the rail onto the action with this stuff and it should be fine. To be on the safe side I would make a plate to fit the recess on the side of your action where you want to mount your rail, ( this way there will be pleanty of surface area to bond) weld the rail onto the plate and stick the plate in place, it would never move and would be very easy to install. Pre drill the access holes in the plate for the reciever pins, and mask the end of the pins so the don't get glued. It would be the perfect non gunsmithing solution that everyone is after.
 
This is a great idea Flob. What thickness of plate would you use? (If I remember right it was 1/4"). And what type of metal did you use for the plate?

I think I would use a piece of steel aproximately the same thickness as the bottom step of the reciever, but I don't think it's important as long as it's rigid. Steel, aluminium or brass will all do the same job, but I prefer steel myself. As for the rail backing, you would need to measure the thickness needed, but as your mount is not the type that goes over the action all you need to do is make sure the mount does not come into contact with the upper step on the reciever. You may find you need no rail backing at all.

When fixing the mount you would need to carefully mask the surrounding area and clamp it in place. It takes about 24 hrs to cure properly. It would be bonded on the top and bottom as well as the back, so it will never shift. I think it will be stronger than screwing it on.

PS, there is a slope on the upperside of the bottton step ( least there is on mine ) the plate would need carefull fitting at this point to make a neat and tidy job, but it's straightforward enough.

You know the high strength epoxy idea sounds rather good. Would you need to remove the finish (paint) in order to get a good metal to metal bond?

It might scare a few people to glue tings on to their rifles and it does sound hokey, but when you think about aircraft parts being glued together it makes sense. I'm guessing since it's way back on the action there won't be any heat issues either.

Plus, if the scope recieves a blow hard enough to knock the side plate off then chances are the optics are going to be screwed anyways :)

I would say so

There are loads of plastics used in firearms these days, think of it as modern silver solder.
