Remember this guy?

Ya know, nice rifle, cheap scope?



Well, we made it to the long range today. First things first, warm up and sight in at 100 yards. Not bad!



No, it's not MOA, that group measures 1 and 1/16 inch, so I can't claim MOA. The others at 100 were similar, nothing spectacular. Adjust right two clicks and be happy.

So, here, we go...go for broke...200 yards...and.....

Ya know, there is this weird thing called bullet drop? I had forgotten. I had nicks in the bottom of the target, as my load showed a drop of almost 5 inches at 200 yards. Great Caeser's Ghost, that's a rainbow! 
OK, start adjusting scope up, (wrote down how many clicks so I could put it back to 100), and here's what we got.

Right before last adjustment,



I can live with it, 2 3/4 inch group. Move scope up on last target,



We have room to grow in, that's for certain, 3 inches right there. Also made an important discovery - the CZ 527 does NOT like Fiocchi brass! I have a bunch I worked on last night, full case prep like I don't normally do with rounds for the vz-58, and I am gonna start working some new laods up, see if I can tighten that up a skosh or two. The range was starting to fill up, so I packed up and left.
CZ-527M carbine, 7.62x39mm - I like it.

No 4227, but I do have H335 and H 4895. I have a few Speer HotCore 125grain FMJ, plus my usual hornady 123grain FMJ and SP. Any thoughts using those?

thats one nice carbine amoredman, and at 200 yards i must say thats impressive for a carbine

Close enough!  I think your Rifle and Scope are working well for you!

I have my Ruger Mini-30 sighted in, about 2 inches high at 100 yards, using South African FMJ loadings.  I'm still in the process of fine tuning it.

AA1680 is a very good powder for the 7.62x39mm!  I use H335 for the 5.56x45mm.  You might experiment with heavy 150/154 grn game loads, similar to what Wolff imports for Deer Hunting if you can find Data.

I like the H335. I have never used the Speer bullets. The CTQ here is the diameter. The 527, in 7.62x39, as well as the vz58 have .310 bore diameter per Mike Eagleshield. My 527 with .310 -.311 is a tack driver.  With .308 not so much.  I've always used Sierra. I got hooked on those way back in the day. I use a 168gr HPBT Matchking at work occasionally, so it just kind of carried over.  I heard Hornady makes a great bullet for 7.62x 39.

[armoredman]

Yeah, I never tried using a .308 bullet, since I always loaded for ComBloc designs, plus I believe it was only the furst run of Ruger Mini-30s that had .308 barrels. I'll be experimenting now, and see what I can do with it.

[jwc007]

plus I believe it was only the furst run of Ruger Mini-30s that had .308 barrels.

Actually Ruger used a Tapered Bore that started .311 at the throat and tapered down to .308, so that theoretically, .308 Bullets could be used as well.  Mine has it, but .310 inch bullets work best in it, so far.  .308 inch bullets, so far, not so much.  I may have to reload more for it if the Heavy 154 grn Wolff Loads cannot be found and bought.  The good stuff (ammo in particular) is scarce around here.  Reloading supplies as well.
