Does anyone have any real world hunting experience with this bullet out of any 7.62x39?

The reason I ask is that I have a CZ 527 that I want my step daughter to use on her first mule deer and antelope hunt (both does).

We're going to build her her own 7.62x40 WT this next winter, but I feel more comfortable with her shooting a bolt or single shot this year.

The original plan was for her to use a 6.5 TCU in a Thompson Contender rifle, but she just doesn't have the hand strength to be able to break the action open so it's a no-go! (I'll probably use it for one animal just to get it bloody![wink]

So far in initial testing the CZ is a real tack driver. I loaded up pressure test rounds with AA1680, CFE BLK, and Shooter's World Blackout. Surprisingly, SWB showed the most velocity (Just north of 2700 fps with 29.0 gr. in new Starline brass, with zero pressure indications.) 

I then loaded up a ladder from 27.6 gr. to 29.0 gr. in .2 gr. increments based off of chronograph readings. I'll be damned if the first three shots from a cold bore didn't go into a .25" group! The rest of the groups performed great with 5 of the 8 loads going into 1" or less, and three of those going into .5" or less! 

Previous chrono readings had shown the 27.6 gr. load to go 2644 fps. so I decided to do a jug test.(I actually did two) Both bullets did massive damage to the first two water jugs, much like a 125 gr. ballistic tip fired from a .308 Win., at 70 yds.(flat spot on my range) and dimpled the third jug. They retained 56.4 and 52 ish grains, respectively. 

In all honesty, this is what the 120 SST did out of a long barreled 6.8 SPC in a T/C for me years ago. That bullet shot a few animals, but made massive blood shot meat no matter where hit.

My only other option is some old Remington 125 gr. .310 bullets, but they aren't very consistent and were just meant for AK blasting.

I'm sure this combo would work as long as we stay away from shoulders, I just don't want it to "not work" with a new hunter. Thanks in advance. Any help would be appreciated.

P.S.

The "Interweb" doesn't seem to have much info and the closest I've found is based off of the .308 110 gr. version out of a 300 Blackout. I guess if we make her find the animal, then back off an extra 150 to 200 yds, we'll get Blackout performance[wink]

I bought a metric butt-ton of these from SPS to use in my x39 ARs, but haven't shot anything other than paper and steel.  They have proven very accurate though.  Best of luck, I'm sure it will do fine it she doesn't hit a shoulder.

I bought a bunch of them from SPS as well when they did their first pre-production run. I couldn't pass up on the price! I didn't even have anything, at the time, to shoot them in! The ol man had a bunch of AK's, but I decided to use them in an AR that I've never built as of yet. Well, that project never got off of the ground, so here we are.

I am one of those people that will build or buy a gun just because I have bullets (or brass for that matter) that will work in one!

That is a PERFECTLY sound, logical, legitimate, reasonable, and defensible position!  Or so I have told my wife countless times....
