I definitely will. I got a new scope mount ready and I'm itching to get out there to do photos and a video.

Oooooh is that a new load? Shame CB is so damn expensive I bet that'd be a real good social load but it's priced out of my reach, sigh...
Let us know how it performs!

Never the 150 SP....That should be AWESOME!

Do your accuracy testing right...
Gun totally sighted
warm
off a bag

I think you'll be amazed. What AK is this going in? Romy/Yugo/AMD/Bulg/Saiga?????

I bet that will easy knowck one MOA clean off, maybe two. That stuff would be a great reach out and seriously touch someone at 3-5 hunnard yards!

I'm bringing my new freshly converted Saiga and my Vepr.
I plan on shooting them side by side as a comparison with the same ammo.
I got a separate scope mounts this time for each. I will use benched sand bags. A 24x and a 32x scope. Unlike most other 7.62x39 commercial loads which have a slightly undersized bullet .310 or .3095, this is the first comercial
load I seen that uses the proper .311 size bullet. The fact that the bullet is made by sierra also makes this a very interesting load.

how much better is it over the Wolf brand ammo and how much more expensive is it?

It actually mushrooms like a soft point is suppose to according to what I have seen about sierra prohunter 30 caliber bullets. Sierra makes these bullets
balanced enough to spin in much higher RPMs than most any other domestic hunting bullet. Probably not that far off in balance from their match king bullets which are Sub .3 MOA potential in very good bolt guns.

Wolf black box bullets are far from being any where as near balanced as these and after measuring several wolf bullet diameters with calipers I saw
.3105, .3102 , .3097, etc Not having consistent diameters is really bad for
accuracy. The actual weights vary as well and the powder charges vary enough to make them inconsistent. I can't remember where I saw a video of someone pulling the bullets and comparing wolf to other russian ammo.
It really trailed behind barnaul consistency or ULY. Wolf is the bottom of the totem pole in quality.

:wow: 150 gr. ? I've never seen that before. I bet that stuff packs a serious wallop.

Looking at the .308 factory loads, at the muzzle, it is similar to what the .308 loads are at 175 yards down range.

There used to be 154gr wolf out there. It worked well on deer out of my sks.

154sp is definitely the "put some hurt" at longer distances round for an AK.

is the cost prohibitive?

Please post range report/pics, I have never seen corbon 7.62X39, should be interesting, tagged for latter

I am sure that ammo would perform very well out of a Yugo SKS as well.

:cool:

As I have always said - crappy ammo is one or two of the MOA on any AK.

Go get some Federal Powershock SP's and shoot that. You'll see. $20 for 20.

I assume the Corbon is more like $50 for 20. But you should treat yourself once just to know it's not the ammo (which leaves you or the gun).

You gotta get out of the cheap rocks attitude. An $800 Bulgarian/Saiga with that corbon is a TOTALLY different creature than a Romy with Bear.

And yes - I find the Corbon VERY prohibitive for every day (or even every month use). But for occasions where accuracy counts (like a hunt, or an SD ready mag)...hard to argue.

I have reloaded 7.62x36. I was not able to better my Wolf group, so very interested in your results.

Please test from a bagged bench, 5 shot group, 1 to the side, measure with calipers.

group-extra hole = final group size.




we will also need a group of wolf or othe mass marketed ammo to judge the corbon to.

I think so, but that's only one man's opinion. $41.40/20 :shocked:

For what it's worth, the 150 Corbon SP has the worst accuracy of any load I've tried in my CZ 527 bolt action 7.62x39. We're talking 4" at 100 yards bad.

Best ammo is Monarch FMJ and Federal SP which both average about 1.5".

All I have on that note is, wow.

Saved me $42.

That is quite the amazing contrast to what Mr. Wayne Sula of Temple, TX
Wrote as a review:

Date posted: 10/13/2009While I have not yet hunted with this ammo I can testify to it's accuracy. I have a CZ 527 carbine topped with a Burris fixed 6x. After sighting in at 50 yards I moved to 100 yards. Without making any adj. for drop the first 5 round group was 1.1 inches, the first 3 of these were sub-moa. Subsequent groups yielded similar results. Because I thought this round not to be particularly accurate I was totally amazed. Can't comment on terminal performance, but this stuff is tops.

I finally finished my load development with my CZ 527 7.62x39
.................................................................................................... ..................................I then loaded Sierra .311 SP bullets with 25.5 grains of R7. Groups ran 1 to 1.25 inch. Now I was getting somewhere.
I loaded Sierra 150gr .311 bullets with 24.8 grains of R7. The first group went into one .75 inch hole!! Of 6 groups the largest was 1.25 inch.
Now the question,

Ok, has the rifling twist rate changed on the 527 7.62x39 in the past few years?

No disrespect intended here but I wouldn't stop an evaluation based on one other person's bad experience with
the ammo in question. Most any review I have read up to now has been really positive about it.

I REALLY wanted the Corbon load to work for me because of the ballistic advantage over other loads. The difference really is significant. While it didn't work in MY rifle, it just might be the ticket in yours. There's only one way to find out and that's to try.

I have no idea if there were twist differences in the CZ 527. The Wolf 154 SP were much more accurate than the Corbons so maybe it's just one of those bad rifle/load combos.

The corbon sp was used on shot #4.

Anything to say on the accuracy buzz? I am going to a range for some 100 yard shooting monday. I want to pick up 80 rds or so of some good ammo to see what I can do with my sgl. Thanks

I have not had a chance to get a decent range trip. I am pushing for this week since I got a better scope mount I been waiting for. The day I did the water jugs video was windy and overcast dark.
